Study on microseismic monitoring and early warning technology for strong mining pressure in Hudi Coal Mine
In Hudi Coal Mine,there are obvious deformation in the roadway during mining,the floor bulges,the two sides shrink,the roof subsidence and the bolt(cable)fracture appear in some areas,which has typical characteristics of strong mine pressure manifestation.In order to ensure the mining safety of the working face of Hudi Coal Industry,taking the working face of 1305(lower)in one plate area as an example,through theoretical analysis,numerical simulation,site measurement and other technical means,the spatio-temporal evolution law of the mining working face was studied,and the critical early warning indicators of the strong mine pressure microseismic monitoring were proposed,and the layout of the current microseismic network was optimized,and the strong mine pressure mi-croseismic monitoring early warning system was established.
