Crawler drill for coal mine underground floor suction roadway all-dip-angle hole drilling and construction method thereof

Abstract

The invention provides a crawler drill for coal mine underground floor suction roadway all-dip-angle hole drilling and a construction method thereof. The drill comprises a platform system, a stabilizing system, an operation system, a power system, an angle regulating system and a drilling system. A crawler vehicle body is used as a platform, and can realize the three-direction stable support; anda host of the drilling system can rotate in two planes parallel and vertical to the crawler vehicle body through being controlled by a machine frame of the angle regulating system, the rotary platform, a sub rotary device and a main rotary device, and can be positioned in any angle. The crawler drill overcomes the defects in the prior art; the hole forming inclination angle can be fast regulated;the transportation dimension can be reduced; the drilling construction condition can be clearly observed; and the problem of rock layer drilling difficulty can be solved. The crawler drill has the obvious advantages that the carrying and the transportation are convenient; the all-dip-angle hole drilling construction efficiency is high; and the drilling is safe and reliable, and the like.

Description

technical field [0001] The invention relates to the technical field of drilling equipment, in particular to a crawler drilling rig for full-inclination drilling of bottom pumping roadways in coal mines and a construction method thereof. Background technique [0002] Gas disaster is the most important and serious disaster type in underground coal mines, which seriously affects mine safety and production. Pre-drainage of coal seam gas by drilling in advance is the main technical means to prevent and control gas disaster accidents. It mainly includes two aspects: one is to prevent Drain the gas in the area affected by the coal roadway to be excavated, and cover the safety of the coal roadway in advance; the second is to pre-drain the gas in the working face to ensure the safety of coal seam recovery at the working face. [0003] Soft outburst coal seam is the main coal seam type in high gas mines and coal and gas outburst mines in my country. It is widely distributed in China, ...
