针对辽宁阜新海州露天煤矿矿山公园建设过程中矿山边坡危岩体和浮石问题,通过现场地质调查与分析,确定出滚石易发区和危险区;运用rockfall数值计算程序,对危险区内的滚石运动轨迹、弹跳高度和总动能进行数值计算,探索最佳滚石防护位置;根据计算结果提出利用SNS防护网进行滚石防护的参数设计。
Aiming at the problem of rock mass and pumice in the slope of mine during construction of open pit coal mine park in Haixu, Fuxin, Liaoning, through the on-site geological survey and analysis, the rock-roll prone area and dangerous area are determined. Using the program of rockfall numerical calculation, The numerical calculation of rolling motion, bouncing height and total kinetic energy are carried out to explore the optimal position of roller protection. According to the calculation results, the parameter design of rolling stone protection by using SNS protective net is proposed.
