Realization and engineering application of hydraulic support optimization in residual coal remining

The hydraulic support is the key equipment of the residual coal stoping working face, which provides the safe working space and the wind circulation channel for the remining. Scientific mining of residual coal is on the basis of the optimization of hydraulic support structure and working resistance . The Hydraulic Support Optimization (HSO) is mainly influenced by geological factors, including seam thickness, dip angle, roof rock fracture...
