本文深入地分析和探讨了采用无底柱分段崩落法开采深埋和软弱破碎围岩的缓倾斜矿床，影响采场巷道稳定性的主要因素。在此基础上，阐明维护采场巷道稳定的三项措施：利、避和制，最后，结合小官庄铁矿西区的开采实践，说明实施这三项措施在控制采场地压、维护苍道稳定和确保矿块正常回采所取得的显著效果。
This paper deeply analyzes and discusses the main factors that affect the stability of roadway in mining area with gently inclined ore deposits that are buried deep and weakly crushed by non-pillar caving method. On this basis, clarify the three measures to maintain the stability of roadway: mining, avoiding and restraint system. Finally, combining with the mining practice of West Area of Xiaoguangzhuang Iron Mine, it shows that the implementation of these three measures can not only control the pressure of stope, Stable and ensure the normal mining of the block has achieved remarkable results.
