中文摘要：
通过研究矸石充填体压实和流变力学性能,综合运用理论分析、UDEC数值模拟等方法与手段,基于岩层控制关键层理论,矸石充填体采场围岩活动规律特征,系统分析了矸石充填对于沿空巷道稳定性的影响规律,从而达到控制巷道变形和特定支护方式的目的,为＂三下＂压煤开采提供一定的理论方法和技术途径。
英文摘要：
Through the research on mechanical properties of compaction and rheological waste backfilling,synthetically using methods like theoretical analysis、UDEC numerical simulation and so on,based on theory of rock control key stratum,build regularity and characteristic of waste backfilling stope surrounding rock activities,analysis is done on effect law from waste backfilling to the stability of tunnel along the empty district systematically,to achieve the goal of control tunnel deformation and application of specific support mode,provide a certain theory method and technical way for exploitation of coal of holding down of under water、under road and under building.
