DEVICE FOR MECHANIZED DRILLING OF BORE HOLES AND WELLS IN OUTBURST DANGEROUS COAL SEAM AT DRIVING OF PREPARATION IN-SEAM WORKINGS THERE WITH DEVELOPMENT MACHINE WITH EXECUTIVE DEVICE ON TELESCOPIC BOOM

摘要

A device for mechanical drilling of bore holes and wells in outburst dangerous coal seam at driving of preparatory in-seam workings there with development machine (DM) with executive device (ED) on telescopic boom (TB) that includes a drill with drill string and rock-destruction instrument, this is fixed on the TB DM behind its ED. To provide possibility of mechanized drilling bore holes and wells it any place of the surface of the working that is driven and in any direction with respect to its axis the drill is equipped with a yoke, prop and two-fork holder. The yoke surrounds the body of the telescopic section of the TB DM behind its ED, the prop with one end is rigidly fixed on the yoke and directed normally with respect to the axis of the TB DM, the two-fork holder is coaxially fixed at the other end of the prop and can turn by 360° with respect to the axis of the prop. The drill with the drill string and rock destruction tool is fixed in the two-fork holder at distance from the axis of the TB DM that exceeds the maximal radius of the ED DM and can turn with respect to the axis of the holder forks, and the whole device can turn with respect to the TB DM by 360° with fixation in arbitrary position through release of the yoke, with its following turn and tightening.
