摘　　要：为了全面评价煤层底板突水危险性,选取断层密度、断层导水性、裂隙发育程度、承压水水压、含水层富水性、岩溶发育程度、强水源补给、隔水层厚度、隔水层强度、隔水层完整性、开采厚度、开采深度、工作面斜长等13个因子作为影响底板突水的主要因素,以物元理论、可拓集合论和关联函数运算为基础,建立了煤矿开采底板突水危险性等级评价的物元模型。应用该模型对淮北某矿3612工作面底板突水危险性进行评价,验证了其正确性。选取近年来煤层底板突水的典型案例作进一步的应用分析,其结果与实际相吻合。基于可拓评判法的煤层底板突水危险性分类具有较高可靠度和实用性,研究结果为煤层底板突水危险性分类提供了一种新的思路和方法。In order to overall evaluating the water inrush risk in coal seam floor, 13 factors including the fault density, the water conductivity of fault, the fracture development degree, the pressure of confined water, the water yield property of aquifer, Karst development degree, the make-up of strong water source, the thickness, strength and integrity of water-resisting layer, the mining thickness and depth and the inclined length of working face were chosen as the key evaluation factors which affect floor water inrush. By taking the matter-element theory, the extenics set theory and the operation of relevance function as the base, a matter-element model for floor water inrush risk evaluation in coal mines was established. Evaluation was made with this model on the floor water inrush risk in 3612 working face in a mine in Huaibei Coal Mining Area, and its correctness was verified. Some typical cases of mine floor water inrush occurred in recent years were selected for further analysis, and the analysis results were consistent with the actual ones. The classification of mine floor water inrush risk based on the extenics evaluation has higher reliability and applicability, and the research results provided a new thought and method for the evaluation of coal mine floor water inrush risk.
