对玉龙铜矿运矿道路区的地形地貌、岩性和地质构造进行调查,获取危岩体的岩体物理力学指标,分析道路两侧的潜在崩塌落石灾害。在对运矿道路两侧边坡地质灾害进行调查的基础上,分析该区的工程地质条件、边坡特征、崩塌落石特点及形成机制。用Rockfall数值软件对落石进行数值模拟,确定落石的运动轨迹、弹跳高度和总动能指标,对防治运矿道路崩塌灾害提供依据。
The topography, lithology and geological structure of the road area of Yulong Copper Mine are surveyed to obtain the physical and mechanical indexes of the rock mass of the dangerous rock mass and to analyze the potential collapse rockfall disaster on both sides of the road. Based on the investigation of geological disasters on both sides of the road, the analysis of the engineering geological conditions, slope characteristics, the characteristics of collapse and rockfall and the formation mechanism of the area are carried out. Using Rockfall numerical software to simulate rockfall, determine the motion trajectory, bouncing height and total kinetic energy index of rockfall, and provide basis for prevention and control of road collapse disaster of ore transportation.
