摘要
文家坡矿井筒具有深度大、断面积大、水文条件复杂等特点。文章通过对回风井基岩段洛河组砂砾含水层特性的分析,运用工作面预注浆技术,较好地解决了井筒涌水、淋水问题,加快了施工进度,确保了工程质量。
Wenjiapo Coal Mine has the characteritics of great depth,big sectional area and complicated hydrologic conditions.This paper preferably solves the problems of water gushging and water drenching of shaft,by means of the property analysis of Luohe group gravel water-bearing stratum of air shaft and the application of the technique of working face pre-grounting.In this way,the construction pace can be sped up and construction quality can be ensured.
