【摘要】 基于某矿矿体内存在高应力和各向应力的不均衡性,利用自行改造的加载设备,进行附加载荷的动光弹模拟试验,研究表明:岩石在高应力条件下产生一个附加强度,使岩石相对难爆,必须适当增加炸药单耗。更多还原

【Abstract】 Based on high and uneven stresses in the orebody of a mine. The dynamic holophotoelastic model ex-periment of rock under various high-stresses are studied by use of reformed loading device. The result of the study has shown that the strength is increased and blasting is difficult of rock under high-stresses conditions and the specific charge would be raised.更多还原
