摘要
某矿箕斗井施工过程中揭露强含水层和部分溶洞裂隙,多次发生大量涌水。在工作面预注浆过程中分别采用了水泥浆、水泥~水玻璃浆液和改性脲醛树脂化学浆液,证明注浆材料的合理使用,止水效果明显,同时加固了井壁。
During the construction of skip well in a mine, strong aquifer and some karst cave fissures were exposed, and a lot of water gushing happened many times. Cement slurry, cement-water glass slurry and modified urea-formaldehyde resin chemical slurry were used in the pre-grouting process of working face, which proved that the rational use of grouting materials had obvious water-stop effect and strengthened the well wall.
