中文摘要：

鉴于上行开采影响因素复杂，根据新疆龟兹矿业西井近距离煤层坚硬顶板等具体地质采矿条件，首先基于传统的比值判别法、“三带”判别法、数理统计法和围岩平衡法的初步判别，再进一步通过井下探测、相似模拟和数值模拟及工程类比等方法，论证了上行开采的可行性。结果表明：尽管上下煤层层间距近，不能满足比值判别法中采动影响倍数的要求，但鉴于层间坚硬岩层的控制作用，该矿上行开采是可行的。现场开采实践证实了上行开采也是可行的。

英文摘要：

In view of the complex influence factors of ascending mining and according to the specific geology and mining conditions of the western mine in Xinjiang Qiuci Mining Industry, such as the close distance coal seams with tight roof,the feasibility of ascending mining method was demonstrated based on traditional ratio discriminance,three zones discriminance,man-thematical statistics,surrounding rock balance method,analog simulation,numerical simula-tion,underground detection and engineering analogy.The results showed that although the upper and underlying coal seams was close and could not meet the requirement of mining influence mul-tiple of ratio discriminance,the ascending mining method was feasible in view of the control ac-tion of hard rock stratum between coal seams,which was also proved by the mining practice.
