| 摘 要： | 为了解决煤矿生产和技术管理中的冲击地压问题,通过RFPA软件分析了在不同煤层强度、不同垂压情况下开孔,对钻孔破坏半径的影响,通过理论分析和回归分析得出了钻孔破坏半径与煤层强度、煤层压力(垂压)和钻孔直径之间的关系,计算结果对于钻孔卸压防治冲击地压有重要的理论指导意义.

| Abstract: | Rock burst is one of difficult problems in the production and management in many coal mines. It is important content for the coal trade to study the measure of the rock burst. This thesis analyses the influence of the destroy radius on drilling hole under different coal seams pressure situation and different coal seam internist. Through theory analysis and regression analysis, draw the a conclusion is drawn of relation between the radius of the destroy boring with coal steam intensity and coal seam pressure situation and boring diameter and the result has theory ethical guiding meaning for preventing rock burst in mining. |
