摘要
卢氏县地灵矿业开发有限公司目前采用的采矿方法存在生产能力低、作业人员安全没保证、浪费矿产资源等缺点。进行的河南省卢氏县夜长坪钼矿自然崩落法开采优化研究,采用三维弹塑性有限单元法,运用岩土工程专用三维应力分析软件(3D-σ)对夜长坪钼矿自然崩落法的矿柱宽度尺寸优化模拟计算。
The current mining method used in Lushi County Diling Mining Development Co., Ltd. has low production capacity, and the operator safety has not been ensured, and a waste of mineral resources. The natural caving optimization study carried out in Yechangping molybdemum mine, Henan Province using three-dimensional elastic-plastic finite element method and three-dimensional stress analysis of geotechnical engineering-specific software (3D-σ) to simulated calculate pillar size.
