基于郭庄煤矿2304综放面运输巷具体地质及生产条件，采用数值模拟对不同煤柱宽度下沿空掘巷围岩应力分布特征进行深入分析。通过构建综放沿空掘巷弧形三角块结构模型，揭示综放面沿空掘巷围岩稳定性机理。根据现有巷道支护理论，提出树脂加长锚固高强锚杆支护系统并进行锚索补强的围岩控制技术。现场实践应用表明：支护方案对综放沿空掘巷围岩变形控制效果显著。
基于郭莊煤礦2304綜放麵運輸巷具體地質及生產條件，採用數值模擬對不同煤柱寬度下沿空掘巷圍巖應力分佈特徵進行深入分析。通過構建綜放沿空掘巷弧形三角塊結構模型，揭示綜放麵沿空掘巷圍巖穩定性機理。根據現有巷道支護理論，提齣樹脂加長錨固高彊錨桿支護繫統併進行錨索補彊的圍巖控製技術。現場實踐應用錶明：支護方案對綜放沿空掘巷圍巖變形控製效果顯著。

Based on the geological and production conditions of haulage roadway at No.2304 fully mechanized caving face in Guozhuang Coal Mine,the stress distribution characteristics of surrounding rocks in gob-side entry driving with different coal pillar width were deeply analyzed by numerical simulation.Through building the arc triangular block structure model for gob-side entry driving in fully mechanized caving face,the mechanism of the surrounding rock stability was revealed.According to the present roadway support theories,the surrounding rock control technology was proposed,which is a resin extended and high-strength rock bolting and anchor ca-ble reinforcement system.Field practical application showed that the supporting scheme had obvi-ous effect on surrounding rock deformation control in gob-side driving entry of the fully mecha-nized caving face.
