Experimental study on the overburden movement and stress evolution in multi‐seam mining with residual pillars
Abstract When faced with multi‐seam mining, some coal pillars are left to support the overlying strata when mining the lower seam, where stress concentration usually occurs. When the working face in the lower seam advances to the area influenced by these coal pillars, high ground pressure behavior o...
