地下矿山开采系统的岩石力学优化方法及其应用

A GEOMECHANICAL OPTIMIZATION METHOD OF UNDERGROUND MINING SYSTEM AND ITS APPLICATION

本文把地下矿山开采作为一项系统工程来看待。遵循系统工程学的方法和步骤，通过对矿山开采的一般工艺与力学过程的分析，讨论矿山开采系统的岩石力学优化问题；然后以开采过程的数值模拟和数理统计学为基础，提出其优化方法与步骤，并简要介绍为此目的而开发的计算机程序；最后以华北某地下矿山为例，给出了上述方法和程序的实际应用。

In this paper,geomechanical optimization of underground mining system is considered as a systematical engineering problem,and discussed in the light of the principlesand procedures of systematical engineering,Based on the numerical simulation of underground mining and mathematical statistics,a set of method and procedures to geomechanically optimize underground mining system are proposed.Finally,in a case study,the geomechanical optimization of the panel mining system of a large underground mine in Northern China,is given to illustrd,the application of the above method and procedures.
