摘要
通过研究奥陶纪灰岩含水层的岩性、补给、径流、排泄条件等,对矿井综放工作面底板受采动影响、突水系数等综合因素进行可行性分析。在工作面掘进过程中与回采前采取物探、钻探、化探等工作,查明工作面顶、底板地质构造情况,分析出由导水通道出现突水的规律,保证了工作面的顺利安全回采。
Through the study of lithology,recharge,runoff and drainage conditions in Ordovician limestone aquifer,we carry on feasibility analysis for the floor at fully mechanized working face affected by mining and water inrush coefficient and other comprehensive factors. In the process of working face advancing or before mining,we adopt geophysical prospecting,drilling,chemical exploration,and find out the geological structure of working face roof and floor,and analyze the laws of water bursting in water- conducting,which ensures the smooth and safe mining of working face.
