摘要
为了解决在对采空区地面塌陷危险性评价中危险性的影响因素众多,各因素影响程度不同,因素之间关系复杂、不确定性强的问题,就如何合理地构建评价模型进行研究。研究过程中发现,未确定测度相关理论能够很好地解决对采空区地面塌陷产生影响的诸多不确定因素的问题。结合采空区地面塌陷实际情况确定了年降水量、覆岩结构稳定性、矿柱尺寸和位置等15种影响因素,运用改进的层次分析法和熵权法确定组合权重,引入置信度原则,建立了基于确知理论的采空区地面塌陷危险性评价模型,并将模型应用于张家峁煤矿I区,评价结果与实际现状一致。
In order to solve the problem that there are many factors influencing the risk of the hazard in the ground collapse in the mining area, the influence degree of the factors is different,the relationship between the factors is complex and the uncertainty is strong,studies how to construct the evaluation model reasonably. In the course of the study, it is found that the undetermined measurement-related theory can solve many uncertain problems which have an impact on the ground collapse in the mining area. Determines 15 influencing factors such as annual precipitation,structural stability of cladding,column size and location, uses entropy power method and improved hierarchical analysis to determine the combined weight,introduces confidence principle,and establishes the ground collapse risk evaluation model based on the theory of confirmation. And the model was applied to Zhangjiaxun coal mine I area, and the evaluation results were consistent with the actual situation.
