摘    要:在简要介绍长壁工作面矸石充填采煤原理的基础上,分析了长壁工作面矸石充填开采沉陷机理和过程,提出了矸石充填开采的有效充填厚度和等效开采厚度的概念,建立了长壁工作面矸石充填开采覆岩破坏和地表沉陷的预测模式。并结合兖州矿区某煤矿3煤采区地质采矿条件,分析研究了矸石充填开采沉陷控制的具体效果。

关 键 词:矿山测量  开采沉陷  等效采厚预测  有效充填厚度  覆岩破坏  沉陷控制  矸石充填

Abstract:Based on the brief introduction of the long wall workface mining principle stowing with waste dump, the long wall face waste stowing mechanism and process of mining subsidence are analyzed in this paper. The conceptions about effective stowing thickness and equivalent stowing height are also proposed, and the forecasting models for cover rock destruction and surface subsidence of waste stowing mining of long wall workface are established in this paper. With combination of the geological mining condition of 3# coal mining area in Yanzhou coal mine, the specific effect of controlling mining subsidence with waste stowing is analyzed in the paper.
Keywords:mine survey  mining subsidence  forecast of equivalent deep  effective thickness of stow  cover rock destruction  controlling subsidence  waste stowing
