煤矿采场上覆围岩变形特征分析

以四川攀枝花茶叶树煤矿的地质条件为依托，针对茶叶树煤矿35号煤层采场上覆岩层的活动规律进行了研究，通过理论计算和现场检测，分析了煤层开采后上覆岩层移动规律、破坏特点及上覆岩层垮落范围，介绍了覆岩“三带”的大概范围，为深入认识煤矿采场覆岩变形特征提供了指导。

On analysis of deformation characteristics of overlying strata under mining disturbance

Based on the geological condition of Chayeshu coal mine in Panzhihua of Sichuan, the paper researches the movement law of the over- lying strata of No. 35 mining disturbance of Chayeshu coal mine, according to the theory＇ s calculation and site＇ s detection, analyzes the dis- placement law, the damage features and the scopes for the collapses of the overlying strata after excavation, and introduces the general scope for the three zones of the overlying strata, so as to provide the direction for recognizing the deformation characteristics of the mining disturbance.
