成功穿越榆林煤矿斜井流砂层的创新工艺和实施方案

Innovative Techniques and Implementation Plan of Successfully Crossing the Slope Drift Sand Layer of Yulin Coal Mine

榆林煤矿在井筒施工工程中遇到流砂层,且砂层涌水量大,造成各井筒涌水溃沙,给井筒施工带来很大困难,多次发生井筒冒顶和淹井情况,本文通过对施工困难的全面分析,提出了合理可行的解决方案,并且成功穿越了流砂层,为国内建井穿越流砂层开辟了新的途径。

Drift sand layer was met in the shaft construction of Yulin Coal Mine, and the large water inflow caused water inrush and sand inrush in all shafts, bringing great difficulties to shaft construction, and roof fall and shaft submergence happened many times. Through full analysis of construction difficulty, this paper proposes a feasible solution and managed to cross the drift sand layer and opened a new way of crossing drift sand layer in shaft construction in China.
