平顶山矿区丁组煤区域瓦斯防治技术研究

Study on Gas Prevention and Control Technology in IV Group Seam of Pingdingshan Mining Area

以平顶山矿区丁组煤瓦斯防治为工程背景,采用现场试验和理论分析,研究了钻孔喷孔实验、突出危险性预测分级技术等。在瓦斯地质规律研究及区域突出危险性预测分级、防治技术的基础上,论述了不同突出危险性区域瓦斯安全高效开采模式的效果与应用。

In the IV group seam of Pingdingshan mining area gas treatmentas the engineering background, the method combined with a theoretical analysis site test were applied , and plotting danger zone of outburst for working face, is the premise of actualizing classification management of mine outburst. On the basis of the analysis of coal mine gas -geological laws and outburst laws, and classifying management, the effectiveness and functions of the safe and high-efficient exploitation mode are provided.
