Initial weighting strength control of thick and hard roof based on pre-splitting blasting of whole roadway roof: numerical model and engineering verification
Thick and hard roof poses safety hazards to initial mining and caving of the working face due to its good integrity and large modulus. Taking the initial mining of No. 24110 working face in Nanyangpo mine as the background, this study proposes the “shallow-hole intensive blasting-deep-hole direction...
