厚松散层承压水下采煤覆岩载荷层结构分析

Analysis on Overburden Load Structure in Mining Under Thick Loose Layer with Confined Water

在分析厚松散层承压水地质资料的基础上,判断承载关键层的位置,建立承载关键层模型。采用数值模拟手段,建立含承压水和不含承压水模型,分析厚松散层承压水对工作面支撑压力的影响,对预防工作面压架事故的发生具有重要的理论意义和实践价值。

Based on analyzing the geological characteristics of thick loose layer with confined water, the load key strata position is judged, the model of loading key strata is established. By the method of numerical simulation, the models of confined water and excluding confined water are established, the influence of thick loose layer with confined water on the working face support pressure is analyzed. It has important the theory significance and the practice value for preventing the accident of working surface pressure frame.
