Abstract
ENG: The article presents the design of the heading set of equipment for drivage of
development galleries in rocks prone to gas-dynamic phenomena. This equipment can carry out
the full technological cycle of rock excavation. The use of the P-110 roadheader of Ukrainian
PJSC "Novokramatorskyi Machine Building Plant" with an operating device on a telescopic
boom is offered for the aggregation of the heading set of equipment for underground
development galleries drivage in emission-hazardous rocks. The device for mechanized
boreholes drilling in an emission-hazardous coal seam has been devised based on the
EBGP-1 M drilling machine of the Ukrainian SPA "Chervonyi Metalist Co Ltd". This device is
placed on the telescopic boom of the roadheader. For mechanized drilling of explosive,
degassing, unloading and injection boreholes, a rock-breaking tool has been proposed that can
perform an effective vibratory and rotary loading method of drilling in medium-hard and hard
rocks. Safe methods for underground development galleries drivage in gas-bearing emissionhazardous
rocks have been worked out. The effectiveness of these methods was determined in
industrial conditions. It is possible to conclude that this new heading set of equipment and
technology can be recommended for implementation in the mining coal industry.
