Underground tunnel drill rig device based on forced water spray for limiting fire explosion and drilling method

Abstract

The invention relates to an underground tunnel drill rig device based on forced water spray for limiting a fire explosion and a drilling method. The underground tunnel drill rig device comprises an underground tunnel drill rig device body, a first main part, a second main part and a controller (9). The underground tunnel drill rig device body is provided with a drill rig (1) and a water injector (4), the first main part is arranged on the drill rig (1) and used for controlling the work state of the drill rig (1), the second main part is arranged in the water injector (4) and used for collecting water flow signals in the water injector (4), and the controller (9) is set to be connected with the first main part and the second main part and used for processing signals. By means of the secondmain part, it is achieved that water flow signals of the water injector (4) serve as basic signals; by means of the first main part and the controller (9), control over the drill rig (1) is achieved;by means of the underground tunnel drill rig device body, drilling work is achieved; and thus the phenomenon that drilling work is carried out in the situation that no water is injected is avoided, and the safety performance of coal mine underground drilling work is improved.

Description

technical field [0001] The invention relates to a tunnel drilling device and a drilling method, in particular to a tunnel drilling device and a drilling method based on forced water spraying to limit fire and explosion. Background technique [0002] Tunnel drilling rigs for coal mines are used to drill holes in the mining face. They are used to: ascertain the structure of surrounding rocks, reveal the occurrence of ore bodies, detect dangerous conditions such as groundwater and gas in advance in mining tunnels, discover blind ore bodies, and replace some Exploring the tunnel or guiding the direction of tunnel excavation, etc. Therefore, the tunnel drilling device and drilling method based on forced water spraying to limit fire and explosion are an important mine device. And in the drilling method, the drilling operation of the drilling rig must be filled with water. Adding water can be used to cool the temperature of the drill bit and smoothly discharge the slag through the ...

[0002] Tunnel drilling rigs for coal mines are used to drill holes in the mining face. They are used to: ascertain the structure of surrounding rocks, reveal the occurrence of ore bodies, detect dangerous conditions such as groundwater and gas in advance in mining tunnels, discover blind ore bodies, and replace some Exploring the tunnel or guiding the direction of tunnel excavation, etc. Therefore, the tunnel drilling device and drilling method based on forced water spraying to limit fire and explosion are an important mine device. And in the drilling method, the drilling operation of the drilling rig must be filled with water. Adding water can be used to cool the temperature of the drill bit and smoothly discharge the slag through the drill pipe. The existing drilling rig water injection is realized by the coal miners directly connecting the underground water source of the coal mine to the water injector through the water pipe. , but when there is improper operation and drilling operations without adding water, due to the heat generated by the friction between the drill bit and the coal seam, and the cinder clogging in the drill hole, it is easy to cause a fire hazard. If the gas content between the coal seams is large, it will occur Explosions have seriously affected the safe production of coal mines, and there is no tunnel drilling rig device that realizes linkage between the drilling rig and the water injector
