Coal mine downhole crawler type drilling and punching integrated equipment comprises a crawler type hydraulic drilling machine, a high-pressure-resistant sealing drill stem, a drilling and punching dual-purpose drill bit, a high-pressure rotation connector and a high-pressure water pump station, wherein the body of the high-pressure-resistant sealing drill stem penetrates and is fixed in the power head inner hole of the crawler type hydraulic drilling machine, a power head provides rotation speed and torque to the body of the high-pressure-resistant sealing drill stem, one end of the high-pressure-resistant sealing drill stem is connected with the high-pressure water pump station through the high-pressure rotation connector, the high-pressure water pump station provides high-pressure water needed by punching, the other end of the high-pressure-resistant sealing drill stem is connected with the drilling and punching dual-purpose drill bit, and hydraulic operations can be performed after drilling without replacing the drill bit. The coal mine downhole crawler type drilling and punching integrated equipment has the advantages that streamlined operations of coal mine downhole gas pressure relief, drilling and punching can be completed by the equipment, safe and efficient production of outburst mines is guaranteed, coal seam coal and gas outburst danger is eliminated, a regional pre-drainage gas drilling construction period is shortened, coal seam drilling and punching and gas extraction efficiency are increased, and gas disaster prevention and control cost is reduced.
