炮孔不偶合装药爆破时,爆生气体准静压力是爆生裂缝产生的主要原因。作者运用岩石强度理论和岩石断裂理论,分析探讨此装药条件下爆生裂缝的扩展长度。
When the blasting hole is not coupled with charge blasting, the quasi-static pressure of the blasting gas is the main cause of the blasting fracture. Using the rock strength theory and the rock fracture theory, the author analyzes the extension length of the crack in the explosion under this charge.
