摘要
为解决大平煤矿3108工作面在陷落柱影响下的空巷安全开采问题,防止回采期间的漏冒顶事故的发生,根据工作面的地质条件,分析空巷位置、断面变化等因素,通过提前调整工作面伪斜及坡度,采用预先加固空巷、强化顶板管理,提出了一系列的优化方案和可行性技术措施,有效的控制了空巷围岩变形,确保了工作面的安全回采,为矿井过空巷积累了宝贵的经验。
In order to solve the problem of safe mining of goaf under the influence of collapse column in 3108 working face of Daping Coal Mine and prevent roof leakage during mining,according to the geological conditions of the working face,this paper analyzes the factors such as the position of goaf and the change of section,and puts forward a series of optimization schemes and feasible technical measures by adjusting the false inclination and slope of the working face in advance,strengthening the goaf in advance and the roof management,effectively controlling the deformation of surrounding rock of goaf,ensuring the safe mining of the working face,and accumulating valuable experience for the mine to cross the goaf.
