- W2033809840 abstract "Abstract In order to study the effect of adopting the technology of coal seam injection to prevent from the happening of rock blast hazards, the paper research on the changes of coal II sample's Impact energy index of Qianqiu mine before and after being soaked by experiments.The results show that sample's Uniaxial compressive strength and Impact energy index have significant linear relationship. Sample's softening water immersion tests proved that coal's Impact energy index will decrease as Uniaxial compressive strength's reduce. Coal seams injection could reduce the strength of coal and then reduce coal's Impact orientation, therefore it will be an effective measure for preventing mine blasts." @default.
