摘要
井筒涌水是煤矿水害的一种,腐蚀提升设备、恶化提升环境、缩短井筒服务年限。用传统的水泥浆注浆往往难以达到止水效果。采用新型高分子注浆材料马丽散E进行井筒壁后注浆起到了止水与井壁加固作用,效果显著。
Water burst from shaft wall is a disaster, which etchs equipments , deterriorates working environment and shortens shaft lifetime. Cement slurry - injection is hard to prevent water leaking, and Malishan e slurry - injection may prevent water and strengthen shaft wall better.
