摘要
黄山铜镍矿30#矿体采用自然崩落法开采,在前期原岩应力测试、工程地质调查、可崩性分析、块度分析等研究成果的基础上,用三维离散单元程序3DEC对该矿体采用不同拉底方案开采的崩落规律进行了模拟,研究整个崩落过程中的应力与位移的变化情况,从而确定合理的拉底方案和拉底顺序,对现场实际开采具有指导意义。
The natural caving method was used to mine the30#orebody in Huangshan Copper-nickel Mine.Based on the results of the original rock stress test,the engineering geological investigation,the caving analysis and the lumpiness research,the caving rules of orebody with different undercutting schemes were simulated by 3DEC.The changes of stress and displacement during caving were studied to determine the reasonable undercutting scheme and order,which had guiding significance for the actual mining.
