Abstract

Mine water disaster is closely related to the geological structure of the mine. A scientific evaluation of the complexity of the minefield structure can greatly contribute to mining safety. In this study, we optimized the fault impact index in the study area and proposed an improved local linear embedding (LLE) algorithm by investigating the Shengquan coal mine. We analyzed the fault formation age and connectivity between faults in the study area, combined with topology theory, and based on previous studies. The mechanical properties of faults and the influence of small faults on the strata can be combined to derive a quantitative evaluation model of the structural complexity of mines. Based on the evaluation model, the study area was divided into a simple structural area, a medium structural area, and a complex structural area. By comparing the location of water inrush points in recent years with the three-dimensional high-density electrical exploration of the 21,304 working face, the effectiveness and rationality of structural complexity zoning were determined.

基于改进局部线性嵌入算法的胜泉雷区结构复杂性定量评价

矿井水害的发生与矿井的地质构造密切相关。科学地评价矿区结构的复杂性，对矿山安全生产具有重要意义。本文以胜泉煤矿为研究对象，对研究区断层冲击指数进行了优化，提出了一种改进的局部线性嵌入算法。结合拓扑学理论，在前人研究的基础上，分析了研究区断层的形成年龄和断层之间的连通性。将断层的力学性质和小断层对地层的影响结合起来，可以导出矿山结构复杂性的定量评价模型。基于评价模型，将研究区划分为简单构造区、中等构造区和复杂构造区。通过将近年来突水点位置与21304工作面三维高密度电法勘探进行对比，确定了构造复杂性分区的有效性和合理性。
