【摘要】：为研究矿井防尘供水管网安全可靠性,综合考虑管网运行的影响因素,选取13个评价指标,建立指标体系,划分评价等级。依据未确知测度理论,构建矿井防尘供水管网未确知测度评价模型。以范各庄矿为应用对象,量化各指标,构造指标测度函数;运用信息熵确定指标权重;依据置信度识别准则,得到管网评价等级为Ⅱ级,说明其安全可靠性好。以5个典型煤矿为样本,运用该评价模型,分别得出各矿供水管网安全可靠性等级,并与实际情况对比,评价结果和实际情况相吻合,验证了模型的有效性。
[Abstract]:To study the safety and reliability of mine dust water supply network, considering the impact of network factors, select 13 evaluation indexes, the establishment of index system, dividing the evaluation level. According to the unascertained measure theory, construction of mine dust water supply network model of unascertained measurement evaluation. In Fangezhuang Coal Mine as research object, the quantification, structure index function; information entropy is employed to determine the index weight; on the basis of confidence recognition criteria, get network evaluation grade for grade II, its safety and reliability. In 5 typical coal samples, using the evaluation model, the mine water supply network safety and reliability level are obtained, and compared with the actual situation, the evaluation results and the actual consistent, verify the validity of the model.
