摘要
封闭不良的勘探钻孔对井下采场具有一定危险性,确定其危险性能够为钻孔防治水工作提供技术和决策依据。基于模糊综合分析法,构建了勘探钻孔危险性的模糊评价模型。该模型涵盖封孔位置、封孔质量、揭露层段的泥岩含量、构造发育、揭露的含水层或水体、预计涌水量在内的6个钻孔危险性评价指标,危险性等级分类标准及其对应的模糊量值。模型采用正态型隶属函数确定模糊隶属矩阵,结合熵权法和层次分析综合度量的方法确定权重,通过矩阵运算,综合评价了北皂煤矿10号钻孔的危险性,并对评价结果进行了有效性分析和加权分析,分析评价结果与实际情况相吻合。
Sealing the poor test holes has a certain risk to the working faces, and determining its risk can provide technical and decision-making basis for the water prevention and control of the holes. Based on the fuzzy comprehensive analysis, a fuzzy risk assessment model for the test hole was established. The model contained six hole risk evaluation indexes including the hole sealing position, the hole sealing quality, the mudstone content in the exposed section, the structural development, the exposed water-bearing bed or water body and the expected water inflow as well as the risk classifications standard and its corresponding fuzzy value. The model used the normal distribution membership functions to determine the fuzzy membership matrix and adopted the entropy weight method and analytic hierarchy process to determine the weight of the evaluation indexes. Finally, through the matrix operations, a comprehensive assessment was carried out on the risk of No. 10 test hole in Beizhao Coal Mine, and the efficiency analysis and weighted analysis were made on the evaluated results, the evaluated result accorded with the actual situation.
