| 摘 要： | 基于GIS与熵值耦合理论的矿井断层构造复杂程度的综合评价方法,建立了断层构造的非线性特征值、断层规模指数、煤层底板倾角指数、断层断距指数等与矿井构造复杂程度相关的评价指标体系。并以河南某矿为例,对矿井断层构造复杂程度进行多因素评价综合分区。结果显示:该矿井构造以中等和简单为主;在构造简单-中等区,构造对煤层开采基本无影响,而在构造复杂区,断层可导致水文地质条件变得较为复杂,影响煤层安全开采。

| Abstract: | The mine fault structure complexity comprehensive evaluation method based on the GIS and entropy coupling theory, estab-lished evaluation index system of fault structure nonlinear eigenvalue, fault scale index, coal floor dip angle index, fault displacement index related to mine structure complexity. Taking a coalmine in Henan as an example has carried out mine fault structural complexity multifactor evaluation comprehensive partitioning. The result has shown that mine structures are mainly medium to simple, in structurally simplemedium area, structures basically no impact on coal mining;while in structurally complicated area, faults can bring on hydrogeological condition more complex and impact coal mining safety. |
