Problems solved by technology
[0004]The purpose of the present invention is to solve the problem that the drilling position is easily shifted during the drilling process, which in turn affects the working process, and when used for a long time, the drilling edge will be A large amount of water is accumulated on the ground, and due to the special position of the coal mine tunnel, it is not conducive to drainage, resulting in slippery ground, which is not conducive to the problem of workers working at the edge of the drill hole. An adjustable multi-angle coal mining drilling method is proposed. device
