煤矿井筒破坏的模糊聚类分析与评价

Fuzzy cluster analysis and evaluation on coal mine shaft destruction

为了防治煤矿出现大量井筒破坏事故,采用VB语言实现了用模糊聚类算法进行破裂分析,并建立了兖州矿区井筒破坏分析与评价的模糊聚类数学模型.运算结果表明,当截集λ=0.075时,可将已经出现破坏的井筒和未破坏的井筒模糊聚类为两类,据此可以评价、预测井筒今后破坏的可能性.参考预测结果,2005年兖矿集团对济宁3号井进行了预防性工程治理.

In order to prevent mine shaft destruction accidents, mine shaft destruction were analyzed by fuzzy cluster algorithm based on VB language and the fuzzy cluster mathematic model of the analysis of mine shaft destruction in Yanzbeu. Operational results indicate that when cut set k =0. 075, fuzzy clusters of destroyed shafts and undestroyed shafts can be classified into two types to analyze and evaluate the possibilities of future mine destructions. Using this results, a preventive control measurements over shaft 3 in Jining Coal Mine of Yanzhou Coal Mine Group were conducted in 2005.
