Quantitative evaluation of mine structure complexity and its coupling analysis with water bursting
-
摘要: 多数矿井涌(突)水事故与矿井地质构造有着密切关系，准确评价矿井构造复杂程度对矿井水害防治具有重要意义。以徐庄煤矿为研究对象，选取断裂分维值、断层强度指数、褶皱平面变形系数作为影响矿井构造复杂程度的评价指标，采用独立性权系数法确定各评价指标所占权重，通过ArcGIS建立了矿井构造复杂程度定量评价模型，将研究区划分为复杂构造区、较复杂构造区、中等复杂构造区和简单构造区4个区域，并分析了矿井构造复杂程度与矿井涌（突）水的耦合关系。结果表明：研究区以复杂构造为主，构造复杂程度主要受控于大型断层和褶皱；断裂分维值、断层强度指数和褶皱平面变形系数越大，矿井构造复杂程度越大，涌（突）水点分布越密集，表明矿井构造对涌（突）水具有明显的控制作用。Abstract: Most mine inrush accidents are closely related to mine geological structure, so accurate evaluation of mine structure complexity is of great significance for mine water disaster prevention and control. Taking Xuzhuang Coal Mine as a research object, fault fractal dimension value, fault intensity index and folding plane deformation coefficient were selected as evaluation indexes affecting mine structure complexity. The independent weight coefficient method was used to determine weight of each evaluation index. The quantitative evaluation model of mine structure complexity was established by ArcGIS to divide the study area into the most complex structure area, more complex structure area, middle complex structure area and simple complex structure area, and coupling relationship between mine structure complexity and mine water bursting was analyzed. The results showed that the study area is dominated by the most complex structure and mine structure complexity is mainly controlled by large faults and folds. The water bursting points are more densely distributed with increase of mine structure complexity when fault fractal dimension value, fault intensity index and folding plane deformation coefficient become greater. It indicates that mine structure has an obvious control effect on water bursting.
