摘要
破碎带富水层是鑫阳矿业公司竖井施工所面临的重要工程地质问题,根据竖井所处的工程地质条件,选择对地下涌水具有堵、截作用的预注浆处理方案。讨论了预注浆设计中有关注浆压力、范围及扩散半径等设计参数的确定原则;并介绍了注浆方式、钻孔和注浆工艺、结束标准及效果评定等。
Broken stone band aquifer causes geologically great trouble for the work ofpitshaft driving in Yangshan Iron Ore Mine of Xinyang Mining Company. According to engineering--geological condition of pitshaft site, the slurry pre--injection method is selected to block off underground water inrush. The principle of selecting design parameters such as pressure ＆ scope of injection, slurry extent radius is discussed. And the mode, hole drilling, procedure, finish standard and performance assessment of the injection technology are explained.
