THE MOVING DEFORMATION OF UNDERGROUND MINING BED ON THE STUDY OF PRE-ESTIMATION ON MINERAL EARTHQUAKE

Mineral earthquake,generated by the mining activities,has much to do with the moving deformation of underground mining bed.The capacity of the moving deformation of underground mining bed comprises vertical strain and horizontal one,by which we can calculate the releasing energy of the Mineral earthquake.Consequently,we can analyze the size of pre-estimating Mineral earthquake as well as it's spreading.The highly coincidence of on-spot observation note on actual shock times with the overall energy spreading and the result of pre-estimation proves the possibility of the means that the Mineral earthquake's parameters can be pre-estimated by the moving deformation of underground mining bed.
