摘要(Abstract):

在岩性分析、动水压力分析、地压分析、井筒周边稳定预测、模糊聚类分析和数值模拟的综合研究基础上,对刘东煤矿混合立井冻结法施工的适宜性,冻结深度的合理性进行了工程地质论证,取得了十分显著的经济效益。
fter comprehensive resealches on the lithological characters of the test hole,dynamic pressure,geostatic pressure,stability prognosis around the well,fuzzy cluster analysis and mathematic analog,thewriter gave the engineering geological demonstration on the suitability of freezing process and the rationality of freezing depth of the skip--combination shaft in Liudong coal mine,which brought about notable economicresults.

关键词(KeyWords): 冻结法施工,混合井,工程地质性质,方案论证
