Goaf information acquisition device protection structure and goaf information acquisition method

Abstract

The invention provides a goaf information acquisition device protection structure and a goaf information acquisition method, relates to the technical field of mining engineering, and solves the problem of impact or vibration damage to an information acquisition sensor caused by goaf caving. The goaf information acquisition device protection structure comprises a protection beam, a damping box, an outer shell, a waterproof inner shell, a buffer layer and a base, wherein the protection beam is fixed above the outer shell through the damping box; the top of the outer shell is arched; a supporting part and a compression-resistant bulge are fixed on the outer surface of the outer shell; the waterproof inner shell is arranged in the outer shell; the base is arranged below the outer shell; a clamping groove is formed in the base; the buffer layer is arranged between the base and the outer shell; and an information acquisition device is fixedly connected with the waterproof inner shell. The structure is used for protecting the goaf information acquisition device, and goaf information is accurately acquired in time. The structure has a multi-layer protection effect when being impacted, can effectively relieve the impact vibration influence, has a waterproof effect, and ensures effective acquisition of the goaf information.

Description

technical field [0001] The invention relates to the technical field of mining engineering, in particular to a goaf information collection device protection structure and a goaf information collection method. Background technique [0002] In the process of coal mining and after the mining is completed, the spontaneous combustion of coal seams is the focus of fire prevention and extinguishing work. Most of the spontaneous combustion occurs in the goaf, the broken coal pillar of the roadside and the goaf of the filling face. With the increase of demand for coal resources and mining intensity, and the rise of deep coal seam temperature, the risk of spontaneous combustion in goafs is gradually increasing. Gas explosions and secondary disasters induced by coal spontaneous combustion in goafs occur from time to time. Monitoring and early warning of thermodynamic disasters in goafs The problem seriously restricts the green, safe and efficient mining of coal mines. [0003] At prese...
