Study on cracking mechanism and key parameters of roof in gob-side entry retaining by pre-split blasting roof in deep mine
Based on 7135 working face of Qidong Coal Mine, the cracking mechanism of pre-splitting of gob-side entry retaining by roof cutting and the key parameters of pre-splitting blasting are studied by means of theoretical analysis, numerical simulation, and on-site measurement. Under the same blasting co...
