摘要
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。
Study instable rock and floatstone of the landslide which is caused by the construction of Liaoning Fuxin Haizhou coal mine park,identify the susceptible areas and danger zones of rockfall through field geological survey and analysis. Based on rockfall numerical simulation program, simulate the trajectory,jumping height and total kinetic energy of the rockfall in danger zones, and explore the best protective position. Based on the simulation results, the parameters of the rockfall protection are designed by using SNS fence.
