Research on the Influence of Coals Uniaxial Compressive Strength to Impact Energy Index

摘要：

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 samples Impact energy index of Qianqiu mine before and after being soaked by experiments.The results show that samples Uniaxial compressive strength and Impact energy index have significant linear relationship. Samples softening water immersion tests proved that coals Impact energy index will decrease as Uniaxial compressive strengths reduce. Coal seams injection could reduce the strength of coal and then reduce coals Impact orientation, therefore it will be an effective measure for preventing mine blasts.
