Abstract： According to the actual geological situation in Jiangjun Gobi No.2 Open-pit Coal Mine, the article analyzed compared three technical schemes of the curtain grouting, water drainage and curtain drainage. The author thought the curtain grouting was feasible under the geological conditions, which greatly reduced the investment and the production cost of waterproof and drainage, and was beneficial to the slope stability, and provided water security for Jiangjun Gobi No.2 Open-pit Coal Mine development.
