Study on the structural forms of the key strata in the overburden of a stope during periodic weighting and the reasonable working resistance of the support
Abstract Many mines often passively select supports with a higher yield load to avoid the occurrence of support crushing and roof falling during periodic weighting. This method is not conducive to improving production efficiency or reducing mining costs, but it can ensure safe mining. An effective m...
