摘要
以神东矿区大柳塔矿井1203综采工作面为例,运用适合分析岩层断裂和垮落的离散元数值模拟软件,建立了相应的数值分析模型,进行动态数值模拟计算。其结果揭示了浅埋煤层关键层结构变形破坏规律,给出了控制关键层切落失稳的开采高度为2 m,为神东矿区的保水开采和生态环境保护提供了重要的参考依据。
Taking longwall face 1203 in Daliuta mine of Shendong mining area for example, the paper sets up the corresponding numerical model by numerical simulation software which adapts to analyzing the rupture and collapse of the rock strata and makes dynamic numerical compute. The result of simulation reveals the failure rules of the key stratum structure, shows up the mining height which control the s/iding of the key stratum structure is 2 meter, and supplies the foundation for the water-preserved mining and environmental protection in Shendong mining area.
