摘要
为科学合理地评价工作面受顶板水害的威胁程度,选取了4个方面11个指标作为评价因素,将工作面顶板水害威胁程度分为安全、较安全、一般、较危险和危险,利用语气算子比较法和Matlab软件确定了各评价因素的权重,采用三角形隶属函数建立了模糊评判矩阵,最后利用二级模糊综合评判法对某工作面所受顶板水害威胁程度进行了评价.研究结果表明:通过对工作面地质、水文地质条件和疏放水效果的分析,基于模糊综合评判法的工作面受顶板水害威胁程度评价结果符合实际情况,可以作为工作面开采前安全性评价的参考依据.
In order to scientifically evaluate the threat degree of the water hazard from working face roof, 11 indexes from 4 aspects were selected as evaluation factors, and the threat degree was divided into safe, relatively safe, normal, relatively danger and danger. Linguistic variable comparison method and Matlab were used to determine the weights of evaluation factors; fuzzy evaluation matrix was established by triangle membership function. Two-step fuzzy comprehensive evaluation method was used to evaluate threat degree of water hazard from working face roof. The results show that based on analysis of geology, hydrogeology condition and water drainage effect of working face, the result of evaluation accords with actual situation and can be a reference for safety evaluation before mining of working face.
