Application of pre-splitting blasting roof-cutting pressure relief technology for roadway protection under hard roof
Abstract The 360,606 working face of Xinji 1# Mine was taken as an engineering case to address the significant safety hazards associated with coal mining under hard roof. A key technical scheme for pre-splitting blasting roof-cutting pressure relief was developed by theoretical analysis, numerical s...
