基于突变理论的采空区风险评价模型研究

首次将系统新三论之一的突变原理应用于采空区稳定性评价的研究中,介绍了突变评判法的基本原理和使用步骤.对岩石力学、空区几何参数和空间分布参数设置等基本要素进行分类,构建了影响采空区稳定因素的指标体系,并以该指标体系为基础,构建了采空区风险评价的突变模型.对铜矿采空区稳定性状态进行定量评价,确定采空区的风险等级,结合原始数据得出影响采空区稳定的主要因素,提出相应的治理措施.

Based on Catastrophe Theory of gob mutation Risk Evaluation

This article describes catastrophe theory(which one of the Three of the new system) for the first time used in stability assessment of mined area studies, introduced the basic principles of mutation evaluation and use of steps,to classified the basic elements of rock mechanics, cavity geometry, spatial distribution, constructed a index system of affecting Stabilizing factor, based on the index system, constructed Gob mutation risk assessment model,using Mutation Evaluation to make quantitative evaluation on Copper Mine stability, obtained the gob stability factors, to give the corresponding control measures.
