详细论述了顶板大面积来压的机理，结论认为发生大面积来压的主要原因是煤柱被破坏，煤柱破坏的关键是煤柱面积比率和宽度，而发生大面积来压的范围则主要取决于顶板的厚度或刚度分组厚度，以及岩体强度，切冒型与拱冒型来压是由于覆岩组成刚度不同，均匀和递减刚度的覆岩多为切冒型，递增和交替刚度的覆岩多为拱冒型，文中给出了预测顶板大面积来压的计算公式，其计算结果，可作为设计和生产管理中选择开采参数的重要依据，文章还预测了两个实例，达到了与实际来压基本一致的效果。
The mechanism of large area pressure on roof is discussed in detail. The conclusion is that the main reason for large area pressure is the destruction of coal pillar. The key to the destruction of coal pillar is the coal pillar area ratio and width, while the range of large area pressure is mainly Depending on the thickness of the roof or the stiffness grouping thickness and the strength of the rock mass, the cut-off type and the arching type pressure are due to the different rigidity of the overburden strata, and the overburden strata with uniform and decreasing rigidity are mostly cut-off type, incremental and alternating stiffness The overlying strata are mostly arches. The formula for predicting the pressure of large area roof is given. The calculation results can be used as an important basis for choosing mining parameters in design and production management. The article also predicts two examples, With the actual pressure to basically the same effect.
