摘　　要：为了确定兴隆庄矿西风井井筒的稳定性,从卸压槽压缩量、水位降、治理工程服务年限及地层压缩量等方面进行了分析,采用模糊聚类的方法将多因素判别改为单因素判别,对井筒稳定性进行了进一步评价。评价结果表明:兴隆庄矿西风井2016年底具有破坏可能性,经过方案优化比较,西风井应采用“卸压槽+壁后注浆”技术进行治理。In order to determine the stability of the west air shaft in Xinglongzhuang Mine,the pressure relief tank compression,water level drop,treatment engineering service life and formation compression are analyzed.The fuzzy clustering method is used to change the multi factor discrimination to single factor discrimination,and the stability of the shaft is further evaluated.The evaluation results show that the west air shaft of Xinglongzhuang Mine is likely to be damaged by the end of 2016.After the optimization and comparison of the scheme,the west air shaft should be treated by the technology of"pressure relief groove+grouting behind the wall".
