急倾斜煤层开采地表破坏防治技术

Surface Damage Prevention and Control Techniques of Steep Coal Seam Mining

针对急倾斜煤层开采对地表可能引起裂缝或台阶、塌陷坑和塌陷盆地等破坏形态,采取了地表露头煤治理、井下巷道治理及煤柱加固等防治技术措施,研究结果表明,这些防治技术措施能减小急倾斜煤层开采对地表的影响破坏,有效防止矿井水患事故的发生,为以后解决类似问题提供了思路和方法。

Aiming at the potential surface failures might be caused by mining of steep coal seam, such as fissures, steps, collapse pits or collapse basins, prevention and control measures were summarized and applied, such as crop coal governance, roadway governance and pillar reinforcement. The results show that, surface failures caused by steep coal seam mining can be alleviated using the measures, and the mine water disaster can be prevented.
