摘要
分析了井工开采对边坡稳定性的影响,分别对29209工作面和29210工作面影响区域进行了评价,得出结论:该矿由于采空区周围的岩体应力分布发生变化,采空区上方出现冒落带、裂隙带及弯曲带,边坡岩土体的完整性遭到破坏,原岩整体强度降低,边坡稳定性受到影响;29209工作面及29210工作面相互推进工作时,相邻主巷道之间影响较小。
This paper analyzes the impact of underground mining on slope stability, and conducts an evaluation respectively on the impacted areas of 29209 working face and 29210 working face, drawing the conclusion that because of the change of rock mass＇ s stress distribution around the worked out section, the caving zone, fractured zone and bend zone appear above the worked out section, the integrity of slope rock and soil mass is destroyed, and the whole strength of the original rock is decreased, and slope stability is affected. When 29209 working face and 29210 working face promote each other, the impact between adjacent main roadways is less.
