平顶山矿区煤与瓦斯突出的预测及防治

Prediction and control of coal and gas outburst in Pingdingshan Mining Area

针对平顶山矿区瓦斯赋存的地质条件 ,论述了地质构造对煤层瓦斯赋存的控制 ,提出了煤与瓦斯突出的预测及防治措施 ,即采用掘进工作面防突分级管理措施和回采工作面防突措施 .根据平顶山矿区的实际情况 ,对常规的预测方法进行了改进 ,改进后的措施用于平煤八矿己15-13190等综采工作面 ,效果良好 .

Based on the geological conditions of gas in Pingdingshan Mining Area, geological structure to control gas in coal seam is introduced, the prediction and control measures of coal and gas outburst are put forward. The measures are the sectional management measure for outburst prevention in mine roadway heading face and the measure for outburst prevention in coal mining face. Based on the actual conditions in Pingdingshan Mining Area, the conventional prediction method is improved. The improved measures was applied to the Ji 15 -13190 fully mechanized coal mining face and other faces in No 8 Mine of Pingdingshan and good results are obtained from those faces.
