| 摘 要： | 根据马家沟矿急倾斜煤层开采地表实测资料和现场勘察结果,对地表非连续变形的分布、发育规律进行了研究.研究结果显示,马家沟矿急倾斜煤层开采地面发育大量裂缝,这些裂缝在空间分布上具有间隔性,在时间发育上具有间歇性,对地面沉陷分区性具有控制作用,对采动影响范围扩展具有屏障作用.这些认识对类似条件矿井的急倾斜煤层"三下"开采具有一定参考价值.

| Abstract: | On the base of field survey results and measured data of steeply inclined coal seam mining in Majiagou Coal Mine,the distribution of discontinuous deformation of surface and development law is studied.The achievement shows that the steeply inclined coal seam mining generate surface cracks in the mine have a lot of functions.They control the division of the surface subsidence and confine the expansion of the mining induced effective owing to the distribution of the cracks in space and time.The cognition has ... |
