理想石门揭煤突出危险性预测实验研究

Experimental Study on Predicting Outburst Hazards by Using Ideal Crosscut for Opening A Coal Seam

本文从煤与瓦斯突出过程的能量变化的角度,提出了预测突出矿井的"理想石门揭煤"模型和相应的预测指标,通过对理想石门揭煤进行模拟实验,对理想石门揭煤突出危险性进行预测,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。

In view of the energy changing in the process of coal and gas out burst, we have proposed a model and a corresponding prediction index, f, or ideal crosscut for opening coal seam in an outburst prone mine. Through simulation experiments, we have predicted the outburst hazards in opening a coal seam by an ideal crosscut. And by using quantitative approach, the magnitude of possible dynamic phenomena in opening a coal seam by the ideal crosscut could be classed into three categories： non-outburst proneness, extrusive emission; and outburst proneness.
