摘要
根据西南岩溶地区煤层顶板水害的特点,从水源特征、开采扰动、隔水层性能及地质构造4个方面出发,分析选取了相应的评价指标,同时结合模糊层次分析法确定评价指标权重,探讨了一种西南岩溶地区煤层顶板水害危险性评价指标体系及评价方法,并结合具体工程实例,对某典型煤矿顶板水害危险性进行了评价,可为今后煤层顶板水害预测评价的研究提供一定的借鉴。
Based on the features of roof water disasters in Southwest Karst area in China and starting from the features of water source, the mining disturbance, the performance of water-resisting layer and geological structure, analysis and choice were made on the corresponding evaluation indexes. Combined with fuzzy analytic hierarchy process, the weight of the evaluation indexes was determined, and an evaluation index system and evaluation method for roof water disasters in coal mines in southwestern Karst area were discussed. In addition, risk evaluation was made on the roof water disaster in a typical mine according to a specific engineering example, all of these can provide a certain reference for predictive evaluation of roof water disasters in coal mines in the future.
