摘要
为了确定兴隆庄煤矿副井井筒的安全性,提出了井筒破裂可能性的预测方法。采用了卸压槽压缩量、治理工程服务年限、水位降及地层压缩量因素等判断井筒破裂的可能性,并利用模糊数学将多因素判别变为单因素判别,提高了评价和预测的准确性。评价结果表明,兴隆庄煤矿副井井筒2008年底具有破裂的可能性,应进行预防性治理工程。兴隆庄煤矿依据治理方案对副井进行了治理,保证了井筒安全。
This paper put forward a prediction method of shaft current fracture for ensuring safety of auxiliary shaft in Xinglongzhuang Colliery.This method applied compression amount of pressure-relief slot,service life of treatment engineering,water level decline and strata compression to judging possibility of shaft fracture.It changed multi-factor judgment into single-factor judgment by fuzzy mathematic,which improved precise of evaluation and prediction.Evaluation result showed that auxiliary shaft of Xinglongzhuang Colliery might fracture at the end of 2008 and needed prevention.Actual prevention engineering ensured shaft safety.
