摘要

准确掌握采空区的三维形态和空间位置是进行采空区稳定性数值模拟的关键。介绍了空区三维激光探测系统（cavity monitoring system，CMS）的基本构成、工作原理及探测方法。结合冬瓜山铜矿采空区的实际情况，在采用CMS准确探测采空区的基础上，应用Surpac建立采空区三维模型和矿区地学三维模型，提出采用数据转换的耦合模式将Surpac与Phase2耦合构建数值计算模型，进行数值模拟计算，根据模拟计算结果对采空区的围岩稳定性进行了分析。研究结果表明，将CMS，Surpac和Phase2三者的优势结合起来，可为岩土工程的稳定性数字模拟研究提供一条新的有效途径。

Abstract

An accurate grasp of cavity shape

size and its change is the key to the cavity stability numerical simulation. The basic components

principle and monitoring way of CMS are introduced. In this paper

on the basis of the actual situation of Donggua Shan Copper Mine

the cavity model and geological model of the mine are constructed by using the Surpac software based on CMS. A method of constructing numerical computing model with the coupling of Surpac and Phase2 is put forward. The simulation calculation is carried out. The stability of cavities surrounding rock mass is analyzed according to the simulation calculation results. The research shows that the combination of the advantages of CMS

Surpac and Phase2 provides a new and effective way for numerical simulation research on the stability of rock engineering.
