通过数值模拟分析和现场实测发现,在浅埋煤层工作面其它参数不变的条件下,上覆表土及顶板厚度变化对工作面初次来压规律有明显的影响。该分析结果为预测同类型矿区长壁工作面初次来压步距和防治大面积初次来压造成的灾害提供了一定理论依据。 Through numerical simulation and field measurement, it is found that under the condition of other parameters of the shallow coal seam working face unchanged, the variation of the thickness of the overlying top soil and the roof has a significant effect on the initial pressure law of the working face. The result of this analysis provides a theoretical basis for predicting the first step-pressure step of the long-wall face in the same type of mine area and preventing and controlling the disaster caused by the large-area first-time pressure.
