Background

China is a large coal producing country, gas is the biggest threat of coal mine safety production, more than 70% of major coal mine safety accidents in China are related to gas, and coal mine gas is always a prominent problem restricting coal mine safety, efficient production and sustainable development. In order to avoid the problem of coal and gas outburst caused by the large gas emission in the coal mining process, the gas in the coal seam to be mined needs to be extracted before coal mining. Drilling holes and connecting pipes are adopted to pump and discharge gas in the underground coal mine, which is the most direct and effective measure for reducing the gas concentration. However, in the drilling and pore-forming process, due to the fact that the coal seam has unevenness of a coal body structure in the vertical direction and the transverse direction, coal falling may occur in the drilling process due to the characteristics of low elastic modulus of coal and easiness in collapse, the drill rod is buried and clamped, the drill rod and the drill bit cannot move freely, and drilling and embedding accidents are caused. When the drill rod is stuck and buried, one method is a collision method, namely, a heavy object with the weight of about 30-40 kg is movably sleeved at one end, exposed out of a drill hole, of the stuck drill rod, a stress plate is fixed at the outer end, located on the drill rod, of the heavy object, the heavy object moves back and forth to collide the stress plate, so that the drill rod is vibrated and the collision force moving towards the outside of the drill hole is generated, and therefore the purpose of releasing the drill rod is achieved, and after the drill rod moves outwards to the outside of the drill hole to a certain extent, the stuck drill rod can be taken out by a drilling machine. However, when a heavy object is sleeved on a drill rod and moved, manual work is mostly used, time and labor are wasted, safety performance is poor, and for example, when a hole is drilled in an upward direction, the danger is high when the heavy object is moved up and down to impact a stress plate. To above-mentioned problem, this scheme has provided one kind and has been used for gas extraction drilling to bore with card brill pull throughs.
