| 摘 要： | 富水复杂地质条件下巷道顶底板稳定性较差,以清水营煤矿富水"三软"(顶板软、底板软、煤层软)地质条件作为研究对象,为有效控制软岩巷道变形量,减少巷道维修次数,降低维修成本。通过对清水营煤矿+965 m水平车场底鼓因素分析,提出了适合软岩巷道防治底板底鼓的支护技术,实践证明此方案能够有效控制软岩巷道底鼓变形。

| Abstract: | The stability of roadway roof floor is poor in rich water and complicated geological conditions, so the article took Three- Soft geological conditions （ soft-roof, soft-floor and soft coal seam） of Qing Shuiying Coal Mine as subject to control soft rock dis- tortion of roadway effectively, to keep equipment in service and to reduce maintenance. Supporting techniques that suitable for protecting floor heaven of soft rock roadway was put out by analyzing ＋ 965m landing-station floor heave of Qing Shuiying Coal Mine, and practical applications showed the scheme could control soft rock distortion of roadway effectively. |
