Description

Water damage monitoring equipment for top and bottom plates of deep under-pressure mining working face Technical Field The utility model relates to the technical field of mine safety, in particular to a monitoring device for water damage of a top plate and a bottom plate of a deep under-pressure mining working face. Background Under-pressure mining refers to mining without taking a thinning measure when the thickness of the water-resisting layer is slightly larger than the thickness of the critical water-resisting layer or the water pressure value is slightly smaller than the critical water pressure value under the condition that the bottom plate or the top plate is provided with the confined water-resisting layer. Along with gradual exhaustion of shallow coal resources, the coal field exploitation level is continuously extended to the deep part, and the situation of influence of water damage of the bottom plate is more serious, so that the monitoring of water damage of the top and bottom plates of the exploitation working face is very important. For example, the mine water damage monitoring and early warning device disclosed in the patent with the publication number of CN216477478U is characterized in that a monitoring pipe is arranged at the bottom of a mine, so that the humidity and the pressure in a rock stratum at the bottom of the mine can be measured, and an effective water damage monitoring effect can be realized.
