摘　　要：该文从煤与瓦斯突出过程能量变化的角度,提出了预测突出矿井的"理想石门揭煤"模型及相应的预测指标,通过对理想石门揭煤进行模拟实验,对理想石门揭煤突出预测指标的研究,可以定量地将矿井石门揭煤可能出现动力现象的大小分为非突出,压出及突出三种情况。From the point of the energy changing during the process of coal and gas out bursting, we＇ ve proposed the predicted model and the corresponding prediction index for ideal coal seam crosscut in outburst mine. Through the simulation experiments for the ideal coal seam crosscut, we＇ve predicted the outbursts hazard of ideal coal seam crosscut. And by the quantitative way, the magnitude of possible dynamic phenomena during the coal seam crosscut could be rank into three situations as non - outburst, extrude and outburst.

关 键 词：理想石门揭煤 初始释放瓦斯膨胀能 压出 突出
