鹤壁大矿二＿１煤层附近的小断层多集中分布于焕层顶底板砂岩厚度的低值区，其主要原因是砂岩薄处比厚处更容易发生断裂，这种规律已在生产中得到了证实。笔者利用此规律为鹤壁六矿后期生产选择了４个适合综采的地段。
The small faults near Hebi Daba 2-1 seam are mostly concentrated in the low value areas of sandstone thickness of the top and bottom of the Huan layer. The main reason is that the thin sandstone is more prone to fracture than the thick place. This rule has been confirmed in production . I use this law for the late Hebi six selected four production suitable for fully mechanized mining lots.
