强岩溶地区动水注浆技术探讨

Discussion on Dynamic Water Grouting Technique in Strong Karst Area

摘要:

帷幕注浆是目前解决矿山开采水患问题的重要方案之一，尤其在强岩溶地区，长期大量抽排地下水容易导致环境地质灾害。从帷幕设计、钻孔技术要求、注浆材料、注浆段长、注浆压力、浆液浓度选择、注浆结束标准、跑浆处理措施、效果检验等方面，详细阐述了强岩溶地区动水注浆技术。

Abstract:

Curtain grouting is one of the most important processes to solve the mining flooding, especially in strong karst areas. Long-term substantial pumped groundwater can easily lead to environmental geological disasters. This paper elaborates the dynamic water grouting technology in strong kart area about the curtain design, drilling technology requirements, grouting materials, length of grouting segment, grouting pressure, slurry concentration, grouting completion standard, treatment of slurry overflowing and the effect test.
