通过对义煤集团千秋煤矿二1煤层动力地质灾害现状、特点及影响因素分析,提出了适合巨厚煤层动力地质灾害的危险预测方法、解危措施、解危措施效果检验方法,以及以上工作失败、动力地质灾害突发情况下的应急措施,从而建立了适合巨厚煤层开采的动力灾害防治的安全开采体系,成功地进行有动力地质灾害倾向巨厚煤层的综放开采。
3.
By using of RFPA~(2D),the extremely thick coal seam mined in 21121 fully mechanized sub-level caving longwall working face of Qianqiu Mine,Yima Coal Mining Administration,is studied in detail.
其结果与现场顶煤位移深基点实测结果一致;通过RFPA~(2D)数值模拟实验结果可以看出,工作面超前支承压力作用范围较大,顶煤在运移、破坏过程中层状效应、周期效应较为明显,顶板回转效应显著,并在对巨厚煤层综放顶煤运移、破坏的这些特点进行理论分析的基础上,把顶煤的损伤、破坏直到放出经历的最大达90m的变形、破坏过程划分为初始压缩及塑性变形区、顶煤强烈压缩及破坏区、顶板回转及支架作用区,为巨厚煤层的放顶煤开采奠定良好的理论基础。
