Monitoring and evaluation of disaster risk caused by linkage failure and instability of residual coal pillar and rock strata in multi-coal seam mining
Chinese Academy of SciencesThe researchers established the method of monitoring and evaluation of disaster risk caused by linkage failure and instability of residual coal pillar and rock strata in multi-coal seam mining. The method of monitoring and evaluation not only reduce disaster risk in multi-coal seam mining but provide reference value for the disaster caused by the instability of residual coal pillars during the utilization of closed/abandoned mines.
