    Description MlLZ002 P10135SE Title of the invention.System and method for analyzing drill core samples.
    Technical area.
    The present invention relates to a system for collecting and processing data on the three-dimensional shape and appearance of drill core samples, e.g. drill core samples that areextracted during exploration for natural resources, including such data concerningcharacteristic physical features of those drill cores e.g. planar discontinuities, which systemcomprises a carrier for holding at least one drill core sample. The invention also relates to amethod for measuring, collecting and processing data on the three-dimensional shape andappearance of drill core samples, e.g. such drill core samples that are extracted duringexploration for natural resources, including the characteristic physical features of those drillcores such as planar discontinuities and also including orientation marks on the drill coresamples' surfaces, the method including spatial analysis of the data, e.g. to calculate the orientation of discontinuities relative to the drill core sample axis and orientation line.
    Background.
    Exploration of the above-mentioned type has long been performed in such a way that, afterhaving found a location with an indicated deposit through well-known methods, anexploration drilling is performed in order to obtain a better basis for a subsequent decision ona full investment in further mining operations. During exploration drilling, cores are extracted and then later analyzed in detail.
    When having extracted drill cores in the field from boreholes, the cores are usually dividedinto samples of typical lengths around 1 meter and then stored a few cores together inpurpose-made trays. The number of samples in each tray is usually 4-6, and they are usuallyseparated in separate compartments and marked regarding original orientation in the borehole and order of extraction.
    Among the drill cores there are a number of cores that contain discontinuities and otherphysical features of those drill cores e.g. mineral fabric, and it is of great value to obtain dataon the location and angles of these discontinuities relative to the core axis and the originalposition in the bore hole of the cores, since the discontinuities in the drill core are arepresentation of discontinuities in the bedrock being drilled.
    When looking for discontinuities, the samples are characterized by ocular inspection. Naturalplanar discontinuities can be measured be their Alpha and Beta angles, the angles beingrelative to an orientation line on the core sample, applied when extracting the cores from thedrill hole in e.g. bedrock, and a longitudinal axis of the core sample. lt is also obviouslyimportant that the discontinuities are always documented with respect to borehole and coresample depth.
    One means for measuring the discontinuities is by using a goniometer that is essentially ashort tube of see-through material, which tube comprises marked angle lines and degreesscales around its outer surface area. The tube is positioned with the drill core to be analyzedinside, and by moving it along the core, discontinuities can be measured and documented bycomparing the angles of the discontinuity in question with the marking on the tube. One suchtube is marketed under the Trade Mark EZY LOGGER. Due to that the measurement, usingthe EZY LOGGER, is made by ocular inspection and manual recording, it is almostimpossible to quality control and reproduce the measurement.
    Another way of analyzing is to use the equipment and method that is described in the patentapplication US2009/0080705, where a 2D photo is used in cooperation with a core holdingbox that has calibrated walls for calibrating the 2 D photo. This method uses simplificationsand assumptions that affects the evaluation.
    The common problem with the above approaches is that it is a manual process which canproduce a lot of false data.
    Summary of the invention and its advantaqes.
    An embodiment of the presently presented system for improving the above related processof analyzing drill core structures comprises the following: a. a contactless analytical apparatus for measuring and collecting data on the three-dimensional shape and appearance of at least some part of the outer surface of drill coresamples, b. a first data storage means for storing data collected by the analytical apparatus, c. a processing unit that applies one or more data evaluation algorithms on the data stored inthe first data storage means in order to extract data regarding one or more physical featuresof the drill cores as an output and d. a second data storage means for storage of the resulting output from the processing unit.
    With the presented system, structure data can automatically or semi-automatically be derivedfrom the individual dri| cores while also the accuracy of the derived data is improvedcompared to state of the art technique. ln another embodiment of the system the contactiess analytical apparatus comprises a light-based 3D sensor or a laser 3 D sensor. This type of sensors is easily adapted to generatepoint clouds that can be the basis for the analysis wanted and thus the collected data can bestored as a point cloud in the first data storage means..
    One further embodiment the system comprises a visualization means for presenting datagenerated by the system. With this as an information source an operator can operate thesystem and e.g. chose and feed parameters for entering into the system and its processor, ln another embodiment of the system, wherein the system comprises a component analyzingunit for analyzing elements like minerals etcetera in the core samples, the componentanalyzing unit being movably arranged and dependent on a distance controlling means forcontrol of the distance between the component analyzing unit and the cores being analyzed,information from the processing unit is used to calculate the distance input to the distancecontrolling means. The component analyzing means can then suitably be of an X-ray type.This is component saving as the distance controlling means does not need a distance sensorof its own. The component analyzer unit can suitably be of an X-ray type.
    The method according to the invention comprises the steps of a. using an analytical apparatus for contactiess measuring and collecting data on the three-dimensional shape and appearance of at least some part of the outer surface of dri| coresamples, b. storing of the collected data in a first data-storing means, c. selecting input parameters to mathematical algorithms that are able to create a calculationof a given physical feature in the dri| core sample from the stored data combined with theinput parameters, d. performing a three-dimensional analysis of physical features of the dri| core samples byprocessing the stored data and selected parameters, using a , while relating the analysis tothe spatial position of the feature in the dri| core samples.
    The system can be both manually and automatically operated, the later under completecontrol of a processing unit, implemented by appropriate software.
    Summarv of the drawinds.
    The invention will hereinafter be further described and explained in connection withembodiments shown in the attached drawings, wherein Fig. 1 shows schematically a system set-up with a carrier for dri| cores in scanning positionwith a 3D scanner, Fig. 2 shows 3D point cloud containing a projection of a discontinuity in a core sample, Fig. 3 shows schematically a core sample being scanned by a 3D line scanning laserequipment, Fig. 4 shows schematically a part of a 3D representation of a dri| core where a discontinuityis identified and Fig. 5 shows a block diagram illustrating a method according to the present disclosure.
    Description of embodiments.
    Figure 1 shows schematically a set up for a three-dimensional scanning of dri| cores, takenfrom bedrocks etcetera. The different components shown in the set up are arranged in asupporting lattice or framework (not shown).
    The disclosed embodiment is designed to comprise a laser distancing and rangingarrangement. Thus a scanning unit 5 is arranged above (as seen in the figure but not shownin detail.) a tray 3, which tray in turn is placed on a carrier 2. The tray 3 is designed to beable to house up to 6 dri| cores (not shown) in compartments 8. The scanning unit 5comprises a digital laser/detector unit which comprises a laser, generating a laser beam, anda distance measuring detector means, optically following the laser spot as it is hitting atarget, the spot being arranged to sweep linearly transversely over the core to be measuredfor the moment, one after the other. The scanning unit thus measures along the laser curve,at a large number of points, with a high resolution the distance of points on the particularcurve following the object to be scanned. This generates digitally a curve point cloud,representing a distance curve following the laser line, as the laser beam hits the object to bemeasured.
    As can be seen in the figure 1, the scanning unit 5 is movably arranged and can thus moveback and fon/vard in directions marked by X-axis, equally to Scanning axis. So, whilescanning from one end of a dri| core (not shown) to the other, the scanning unit 5 isarranged, with equidistant small steps in the X directions, to generate a series of digital curvepoint clouds, with a given resolution, parallel to the Y axis. Added together, those curve pointclouds form a 3D representation of the core surface. A scanning unit like the scanning unit 5 is marketed by the company Sitek AB as a “Non-contact distance measurement system”.There is also a unit called “Optocator” marketed by LMl3D. With reference to figure 1, thescanning unit 5 is movably arranged with known technology in Z-directions and the carrier 2is in similar way movable in Y- directions, in order to bring selected cores in scanningposition, into the laser field of view, for the scanning unit. Since the cores are mainlycylindrical, the field of view covers nearly 180 degree around the circumference of the core.
    A 3 D representation, as mentioned above, can be shown as in fig 2 as a point cloud, inwhich each individual point also contains data about RGB or greyscale colour, which, ifpresented on a display, can be interpreted as a “picture”. The resolution of the point cloud infig 2 is changed in order to be clearer to the viewers. ln figure 2 can be seen a discontinuity9. The discontinuity and its position and Alpha and Beta angles can be analyzed as shall beexplained below. ln figure 3, which shows schematic representation of a drill core (here with lines and curvesinstead of a point cloud like the representation in Fig. 2), a laser/detector unit with itsradiation shown as a laser output 10 and a sweeping laser beam 11. As the laser beamsweeps, following a sweeping line transverse to the longitudinal axis of the core 1, it hits apart of the curved surface 12 of a mainly cylindrical drill core, positioned beneath the laser ina tray as described above, and a laser spot curve 13 is generated. The laser field of view, asis shown, covers almost half the circumference of the core. On the part of the half of the corethat can be seen, the core has a reference line 15, which is indicating the “rotational” positionthe core had in its original place in the bore hole. The core is of course placed in the tray insuch a way that the reference line is “visible”, within the field of view, for the scanning unit.The core is also shown with its longitudinal axis 16 marked.
    During the sweeping action over the core, the detector means measures the distance of alarge number of points along the curved surface, generating a curve point cloud. After thatone curve point cloud is completed, the scanning unit generates, with very small incrementalsteps, repeatedly, curve point clouds along the core. As can be seen in figure 3, adiscontinuity 14 is present in the drill core. ln figure 4 is shown a drill core as in figure 3. The discontinuity 14 is marked with three dots,A, B and C. The points A, B and C are marked on three different, separately localized datapoints from the point cloud, which points are generated as the scanning unit has scanned thecore 1. The points A, B and C are here chosen manually by a system operator, but with acomputer data analyzing software they can be chosen automatically. Since the "picture" is adigital, three-dimensional point cloud, the three points together define a plane in a three-dimensional space, which intersects the core, and this plane is a good representation of a specific crack in the bedrock, surrounding the bore hole the core is lifted from. Referring nowto the reference line 15 and the longitudinal axis 16 of the core, the angles Alpha and Beta ofthe discontinuity and thereby the crack plane can be calculated by proper software in a computer or a similar processing unit.
    Figure 5 shows a block diagram explaining a method for extracting information of a three-dimensional point cloud representing the appearance of a three-dimensional object, in thiscase especially a drill core.
    According to this disclosure, an analytical apparatus for contactless measuring and collectingdata on the three-dimensional shape and appearance of at least some part of the outersurface of a drill core sample is used, generating data in a step 20.
    The data collected in block 20 is used as an input for a second block step, comprising storingof the collected data in a first data-storing means 21.
    For processing of data collected and stored in the first data-storing means 21, inputparameters are selected from the stored data and used as selected input in step 22 tomathematical algorithms that are able to create a calculation of a given physical feature inthe drill core sample from the stored data combined with the input parameters, e.g physicalproperties of the drill core. ln the last block 23, finally, comprising a second data storage means, the three-dimensionaldata stored in the first data storage means 21 is processed in a processing unit with theselected parameters, performing a three-dimensional analysis of physical features of the drillcore samples, while relating the analysis to the spatial position of the feature in the drill coresamples. The results of the three-dimensional analyses are stored in the second datastorage means. The first data storing means and the second data storage means can be combined.
    The invention is not limited to the example disclosed and explained above.
    The 3D scanner can be of other type as present on the market as long as it generates adigital three-dimensional data of the scanning object. The laser beam can be arranged in adirection along the longitudinal axis of the core sample to be scanned. The calculation of theplane of a discontinuity can be maid manually, by choosing points in the point cloudrepresenting the surface of the core sample, but can also be made by a computer dataanalyzing system.
    The invention can be used in a system described in WO2011/146014, the content of which ishereby incorporated in this application. This system can be used in combination with a component analyzing unit.
    The system and method is also well suited for exploration and analyzing the ground,bedrocks and the like when planning for construction work like tunnels and buildings ofdifferent kinds, where information on ground stability is very important. lt not limited to groundrocks only but can be used for analyzing other types of drill cores, e.g. concrete drill cores. lt is especially adapted to generate data of Alpha and Beta angles of discontinuities andother planar structures in the core samples, the angles being measured relative to anorientation line on the core sample and a longitudinal axis of the core sample. The systemcomprises a carrier for holding at least one core sample and an analyzing unit. The inventionalso relates to a method for analyzing the structure of drill core samples, e.g. drill coresamples that are extracted during the exploration of natural resources such as ore, oil andgas. lt is especially adapted to generate information of Alpha and Beta angles ofdiscontinuities in the core samples, the angles being measured relative to an orientation lineon the core sample and a longitudinal axis of the core sample.
    The physical features sought can be planar discontinuities, geological fabric, ore veins, drillcore radius or core volume. Different algorithms apply for different features.
    The analysis can include calculation of the acute angle between the drill core axis and thesemi-major axis of the elliptical intersection of a plane and the drill core sample (alpha angle)or the rotational angle around the drill core axis between the drill core orientation line and thesemi-major axis of the elliptical intersection of a plane and the drill core sample (beta angle)The drill core samples can be such that are extracted during exploration for naturalresources, such as mineral resources, oil, and gas, and/or for inspection of bedrock orconcrete structures of buildings or construction creations like walls e.g of dams.
