    Forming a hole between lower and upper parallel galleries formed in a mine by boring upwardly from the lower gallery a bore hole having a first length equal to a fraction of the distance between the lower and upper galleries, then casing the bore hole by thrusting upwardly at least one pipe section having a diameter sufficient to be gripped by the shrinkage of the bore hole into the bore hole. Boring upwardly after casing the first length by a further length equal to a fraction of the distance between the lower and upper galleries, then casing the newly formed further length of the bore hole by thrusting upwardly at least one further pipe section having a diameter less than the inside diameter of any pipe sections previously disposed in the bore hole and sufficient to be gripped by the shrinkage of the newly formed further length of the bore hole through the any previously disposed pipe sections into the newly formed further length of the bore hole, and then repeating the two previous steps of boring a further length and casing the newly formed further length until the upper gallery is reached.

    BACKGROUND OF THE INVENTION The invention relates to devices for drilling and attaching re-setting wells.
    The purpose of the invention is to increase the safety of work.
    Figure 1 shows the device in the initial phase of drilling, a general view; 2 to the same, with retaining devices for the drill rod and casing; fig. 3 - the same, in the later phase of drilling with the use of a step mount.
    The device for drilling and fastening the raised workings comprises a frame I on which a drilling machine 2 and a drilling machine feed unit 3 are moved, moving in vertical guides fixed on the frame 1. On two sides of the frame I of the charter are two vertical working cylinders A, fastened with a horizontal connecting plate 5 for moving it together with a casing 6 mounted on it. Inside the raised pipes 6 there is an elongated section of the drill 7, to the upper end of which a rock cutting tool is attached (drill crown 8). Dp joint retention of the drill rod 7 and casing 6 in the upper part of the frame 1 has a retaining device in the form of horizontally installed working cylinders 9, the clamps 10 are screwed onto the rods of the casing 6. the seizure of the drill rod 7 and casing 6.
    The working cylinders 9 can be adjusted to three positions: when the stem is retracted, fixation does not occur, with the stem fully extended, both the drill rod 7 and the casing pipe 6 are held, and at the middle position only the casing pipe is held.
    In another form of execution (Fig. In the casing 6, there are no windows, and the casing 6 is held by clamping pads 12, while the drill rod 7 is fixed by means of the working cylinder 13 with a latch 14. This form has advantages in very loose layers so that loose material does not penetrate through windows II into the inside of casing 6.

    The casing has an ever decreasing diameter (Fig. 3).
    The device works as follows.
    In the drilling head of the drilling machine
    2, the drill rod 7 is clamped, then the drill crown 8 is fitted, the drive and the feed unit 3 are actuated, and the drilling section is drilled upwards into the coal seam.
    After the completion of the first drilling of the drill rod 7 is held by the latch 10, while the drilling machine 2 by the feed unit 3 is brought to its original position. After that, the first casing 6 is placed on the horizontal connecting plate 5 and the next link of the drill rod 7 is also installed inside this casing 6. Now this second drill rod 7 is connected with the first drill string 7 using the feed unit 3, the holding device is unlocked and The first casing pipe 6 is pushed into the production with the aid of a connecting plate 5 and held by means of a retainer 10 entering the windows I1. The working hydraulic cylinders 4 are returned to their original position.
    The section of casing pipes intended for drilling should not be longer than the drill rod 7 so that the drill bit 8 does not break out of the drill rod.
    After attachment, a second section may be drilled. When the second drilling section is ready, the lower part of the second drilling rod 7 is gripped by retainers 10, which also simultaneously hold the casing of the first drilling section. Now the drill machine 2 and block
    3 feeds can again be retracted to their original position.
    A casing pipe 6 of the second section is placed on the horizontal connecting plate 5 and a third drill rod 7 is installed inside this casing, which is connected to the second drill rod 7, after which the casing 6 rises up to the stop up to the lowest, casing pushed upwards and the connection goes with her. The hold-in-: method is unlocked and the entire row of casing pipes is moved upwards using the connecting plate 5 and vertical hydraulic cylinders 4. By this
