【摘要】 基于煤系地层的层状岩体结构特征 ,对长壁综放开采工作面上覆岩层的活动特点和过程进行了深入的分析 ,由此提出了上覆岩层状岩体运动的 3种基本模式 ,并对离层的类型和控制特点进行了分析。此项研究对长壁综放开采条件下地表沉陷及岩层移动的控制具有指导意义。更多还原

【Abstract】 Based on stratified rock mass structure characteristic of stratum with coal,the process and characteristic of overlying strata movement are analysed in the paper,3 basic patterns of overlying strata movement are put forwarded,and bed separation type of overlying strata and its control characteristic are further analyzed.The study has directly significance to estimate and control surface subsidence.更多还原
