某金属矿床充填法开采稳定性数值模拟研究

Study on Numerical Simulation for Stability of a Metal Deposit Exploited with the Method of Backfilling

针对某金属矿床开采环境较为复杂,采用上向水平分层充填法开采,利用已经掌握的关于空区几何形态、矿岩特性等已知条件,建立矿体三维数值模型,通过数值模拟分析使用充填法开采矿体的稳定性.生产结果表明,应用数值模拟结果指导采矿方法和开采工艺设计是合理的,模拟结果为类似条件下矿山的开采提供了参考.

The mining environment in a metal deposit exploited with the method of backfilling is extremely complex,The paper established the three-dimensional numerical model and analysed stability of ore rock exploited with the method of upward slicing and backfilling on Numerical Simulation by using the geometric shape of goaf and characteristic of ore rock mass had been grasped.The results of production indicate that numerical simulation guiding the methods of mining and design of mining process is reasonable,Simulation results will provide important reference to the similar minings.
