【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,进行附加载荷介质爆破裂纹扩展的模拟试验研究。研究表明:介质爆破裂纹的方向及大小与附加的主应力有关。更多还原

【Abstract】 Based on high and uneven stresses in the orebody of a mine. The blasting crackle spread modelling experiment of the medium under various subjoining-load are studied by use of reformed loading device. The result of the study has shown that the direction and magnitude of the blasting crackle relate to subjoining main stress.更多还原
