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。
富水複雜地質條件下巷道頂底闆穩定性較差，以清水營煤礦富水“三軟”（頂闆軟、底闆軟、煤層軟）地質條件作為研究對象，為有效控製軟巖巷道變形量，減少巷道維脩次數，降低維脩成本。通過對清水營煤礦＋965 m水平車場底鼓因素分析，提齣瞭適閤軟巖巷道防治底闆底鼓的支護技術，實踐證明此方案能夠有效控製軟巖巷道底鼓變形。

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 .
