摘要
针对龙固矿井高压大流量突水的特点,提出"分次注浆,逐步降水"原则,对龙固矿井副井Ⅲ含中进行预注浆堵水项目中的注浆材料选择和注浆工艺等进行了研究,得到较为合理的浆液配比方案。
In view of the characteristics of big water inflow at high pressure in Longgu Coal Mine, a technical solution is proposed in this paper on the principle of "gradual reducing water inrush by separate groutings". A study on the selection of grouting materials and grouting process during the pre-grouting project for water blocking in the Ⅲ water bearing strata in sinking the auxiliary shaft of Longgu Coal Mine. The results obtained produces rationalized formula of grout.
