摘要
煤岩与CO2 突出有别于煤与CH4突出 ,近年来因其在国内外发生较少而研究不多 ,但在窑街煤田它时刻威胁着矿井安全生产。本文分析了獐儿沟井田纵横交错断层的地质构造特性和富含CO2 、CH4的瓦斯地质概况 ,总结出獐儿沟矿煤与CO2 突出的 4个基本特征 ,提出了预测、钻孔预抽、破碎带技术加固。
Based on the complex geological structures and gas (CO 2&CH 4) geological status of Zhang Ergou mine field,four regularities of outburst of coal and CO 2 are reviewed,and systematic prediction methods such as point prediction,prearrange of drilling,reinforcing fracture zone,pipeline monitoring,and construction organization are proposed.
