| 摘 要： | 为了确定纳林河二号矿井31103工作面辅回撤通道区域是否受构造型冲击地压影响,通过对施工煤体大直径卸压钻孔诱发煤体破裂而产生的能量事件进行统计、分析,发现在特厚煤层中部施工的卸压钻孔所诱发的能量事件均位于钻孔至煤层顶板范围,为典型的顶板压力模型,断定不存在构造型冲击地压问题,为了后续的防冲措施实施提供了有力指导。

| Abstract: | In order to determine whether the area of auxiliary evacuation passage in the 31103 working face of Nalinhe No.2 Mine is affected by the impact ground pressure of structural modeling,through the statistics and analysis of the energy events induced by the large-diameter pressure relief drilling of the construction coal body,it is found that the energy events induced by pressure relief drilling in the middle of super thick coal seam are located in the range of borehole to coal seam roof,which is the typical roof pressure model,it is concluded that there is no structural rock burst problem,which provides strong guidance for the implementation of subsequent anti-impact measures. |
