Description

A large-aperture engineering drilling rig

technical field

The invention relates to a large-aperture engineering drilling rig, which is especially suitable for drilling gas drainage holes and pressure relief in mines where gas and pressure are prominent, and for recovering corner coal pillars.

Background technique

Coal seams in most areas of the country are high-gas or high-pressure outburst coal seams. During coal seam mining, if the gas in the high-gas coal seam is not drained or the pressure of the outburst coal seam is released, it is easy to cause safety accidents such as explosions and coal guns. , threatening the safety of workers and affecting work efficiency. At present, the gas drainage method commonly used in mines with gas outburst in China is to dig a gas drainage hole in the coal seam to be mined or in the coal seam adjacent to the coal seam to be mined, insert a steel pipe into the drilled hole, and seal around the hole. Gas extraction; for pressure outburst mines, commonly used pressure relief equipment includes hand-held drilling rigs, column drilling rigs, rack-supporting drilling rigs, etc.; in the recovery of corner coal pillars, there are very few equipments that can be used. Therefore be badly in need of a kind of large-aperture engineering drilling rig that can be used for mining gas and pressure outburst mine gas drainage hole drilling and pressure relief work and the recovery work of corner coal pillar.
