摘　　要：利用ANSYS/LS-DANY软件,对小东沟钼矿典型孔底距和不同孔底距进行了爆破作用过程的数值模拟研究,并进行了工业试验。对试验采用的孔底距爆破效果与数值模拟的结果进行了比较和分析,最终给出了小东沟钼矿的合理单排炮孔孔底距。Numerical simulation of blasting effect process of typical hole bottom distance and different hole bottom distances of Xiaodonggou Molybdenum Mine was studied by ANSYS/LS-DANY software, and an industrial test was conducted. The blasting effect of hole bottom distance used in the test and numerical simulation results were compared and analyzed. Finally, reasonable single-row hole bottom distance of Xiaodonggou Molybdenum Mine was given.
