Abstract Repeated mining is the main factor that leads to development, propagation, and eventual deformation of overlying strata fissures in steeply inclined extra thick coal seams (SIETCS). The evolution structure closely related microseismic events a mine. As depth increases, rules become more complicated can easily induce dynamic disaster accidents. To solve these problems, this paper established physical similarity simulation model. Microseismic monitoring equipment was used study...
During upward backfill mining of the close-distance coal seam group, reasonable design body compaction ratio (BBCR) lower goaf plays a key role in controlling overburden strata movement and deformation. In this paper, feasibility discrimination method caving was adopted; it found that when spacing small, recovery not possible due to instability upper equilibrium structure caused by mining. Hence, proposed; combined with migration control mechanism strata, dynamic evolution crack propagation...
