巨厚表土层井筒破壁注浆技术探讨及工程实践

Engineering practice and discussed of Thick topsoil shaft drill grouting technique

矿井井筒井壁渗漏出水影响生产安全。在充分考虑邱集煤矿的地质条件和进行浆液配比实验的基础上,确定了主、副井筒的合理注浆参数。通过工程实践,使得主、副井筒的涌水量从原来的12m3/h左右降至0.3m3/h,大大节约了井筒的维护成本,提高其安全性能,取得了良好的经济效益。

In full consider the geological conditions of QiuJi mine and proportioning experiment of seriflux, ensure the grouting parameter of the shaft by scientific and reasonable, through the practice, Make the water inflow of shaft reduce to 0.3 cubic meters from 12 cubic meters, economized the preserve cost and enhance the safety performance, Achieved good economic benefits.
