研究表明,层滑构造是煤系地层断块相对滑动的结果,其力学本质是煤层由于其低强度而充当了煤系地层构造作用下的剪切带而发生破坏,煤层越厚,剪切带宽度越大,越易破坏,从而形成了选层性特征,文章以淮南煤田潘三矿为例进行了说明。
The results show that the slippery structure is the result of the relative slip of the faulted blocks in the coal measure strata. The mechanical essence is that the coal seam, due to its low strength, acts as a shear zone under the coal-bearing stratigraphic structure and breaks down. The thicker the coal seam, The wider the width, the easier it is to be destroyed, thus forming the stratification characteristic. The article takes the Pan San mine in Huainan Coalfield as an example.
