Problems solved by technology

[0002] Gas is a precious resource, buried in the coal seam, it is colorless, odorless, unable to help breathing, easy to explode when it reaches a certain concentration, so its mining has certain dangers
Gas explosion accidents often occur in coal mining operations, causing serious loss of life and property
In the existing technology, the gas drainage mainly requires the operator to directly operate the drilling rig to carry out on-site operations in the mine, and the life safety of the operator cannot be guaranteed

Abstract

The invention discloses a remote-control underground gas extraction drilling machine. The drilling machine comprises a host machine of the drilling machine and an electric control system, wherein the electric control system is used for controlling the operation of the host machine of the drilling machine and comprises a main control station, a remote control station and a communication device; and the communication device is used for transferring information between the remote control station and the main control station. In the remote-control underground gas extraction drilling machine provided by the invention, the operation of the host machine of the drilling machine is controlled by the remote control station arranged on the ground, so unmanned operation of the host machine of the drilling machine is realized, an operator does not need to enter a site of a severe environment and the life safety of the operator is guaranteed; at the same time, the operation process of the host machine of the remote-control drilling machine is fully automatic operation, so the operation efficiency is high; and signals acquired by a video acquisition device and a sensor which are arranged on the host machine of the drilling machine can help the operator in the remote control station to know the operation condition of the host machine of the drilling machine at any time, so the reliable operation of the host machine of the drilling machine can be guaranteed.

Description

technical field [0001] The invention relates to a gas drainage drilling rig, in particular to a remote-controlled underground gas drainage drilling rig. Background technique [0002] Gas is a precious resource, buried in coal seams, it is colorless, odorless, incapable of helping breathing, and prone to explosion when it reaches a certain concentration, so its exploitation has certain dangers. Gas explosion accidents often occur in coal mining operations, causing serious loss of life and property. In the prior art, gas drainage is mainly performed by the operator directly operating the drilling rig to carry out on-site operations in the mine, and the life safety of the operator cannot be guaranteed. [0003] Therefore need a kind of gas drainage drilling rig, can realize that the operator just can control the extraction operation of downhole drilling rig on the ground, makes the operator stay away from the operation site, to guarantee its life safety. Contents of the inve...
