| 摘 要： | 基于突变级数理论,分析影响采空区稳定性的因素(包括采空区体积率、距地表的垂深、地质构造复杂程度、煤层倾角、覆盖层厚度、覆盖层类型等),研究采空区塌陷的预测方法.对各影响因素进行排序并确定各因素指标体系,得到各样本的突变级数,从而对采空区稳定性进行预测.实例验证表明,突变级数法的判断结果符合实际,与神经网络分级法的判断结果一致.可见,基于突变级数理论的采空区塌陷预测方法具有科学性和有效性.

| Abstract: | This paper intends to present an integrated evaluation method proposed by us to predict the likely mining collapse accidents based on the catastrophe progression theory. In our study,we have explored a lot of multi-layer objective decomposition activities in the mine,which can be divided into seven influential factors according to the stability of mining geological structures,including volume fractions of mining collapse,vertical depth of the mining layers,their geological structure,coal seam-angular slanti... |
