Crawler drilling rig for full-inclination drilling of bottom pumping roadway in coal mine and its construction method

Abstract

A crawler drilling rig for full-inclination drilling of underground pumping lanes in coal mines and a construction method thereof, the drilling rig includes a platform system, a stabilization system, a control system, a power system, an angle adjustment system and a drilling system, and the crawler car body is used as a platform. It can be stably supported in three directions; the main engine of the drilling system can be rotated at any angle in two planes parallel and perpendicular to the crawler body under the control of the frame of the angle adjustment system, the slewing platform, the auxiliary slewing device and the main slewing device. Positioning; the present invention overcomes the deficiencies of the prior art, not only can quickly adjust the inclination angle of the opening, but also reduces the transportation size, and can also clearly observe the drilling construction situation, which solves the difficult problem of rock formation drilling, and has the advantages of convenient relocation and transportation. It has obvious advantages such as high construction efficiency and safe and reliable drilling with inclination angle drilling.

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, ...
