基于改进AHP-熵权法耦合的淋涌水巷道顶板富水性评价与应用
Evaluation of roof water richness of of water-drenching roadway based on improved AHP-entropy weight coupling
【摘要】 为了实现碱性淋涌水巷道条件下的富水性评价,选取了顶板松动圈范围、顶板裂隙发育程度、温度、湿度、pH值、淋水时间6个指标作为评价顶板富水性的主要指标。综合AHP和熵权法的特点,提出了将改进AHP和熵权法通过最小二乘法耦合的富水性指标权重计算方法。并利用赵楼煤矿5305运输巷道50组现场地质数据,进行了基于改进AHP法和熵权法耦合的淋涌水巷道顶板富水性评价,根据评价结果对赵楼煤矿5305运输巷道强富水性区进行了支护设计,该支护方案能有效控制围岩松动圈发育以及顶板淋水状况,对全矿井和相似地质条件的东部煤矿具有借鉴意义。
【Abstract】 In order to evaluate the water richness of the alkaline water-drenching roadway, six indexes were selected as the main indicators to evaluate the water richness of the roof, including the range of roof loosening circle, the development degree of roof cracks, temperature, humidity, pH value and watering time. Based on the characteristics of AHP and entropy weight method, a method for calculating the weight of water richness index is proposed to improve AHP and entropy weight method through the least squares method. Based on the 50 sets of field geological data of the 5305 transportation roadway in Zhaolou Coal Mine, the water-rich evaluation of the roof of the water-inrush roadway based on the coupling of the improved AHP method and the entropy weight method was carried out, and the support design of the strong water-rich area of the 5305 transportation roadway in Zhaolou Coal Mine was carried out according to the evaluation results.
