Coevolution mechanism and branch of pillar‐overburden fissures in shallow coal seam mining
Abstract The large‐scale mining of coal resources promotes the formation of section coal pillar groups between working faces. The overlying strata are supported by coal pillars, which leads to the formation of a unique fracture‐bearing structure in the key stratum, resulting in the evolution of fiss...
