摘要
根据对下霍井田3#煤层瓦斯含量分布规律和瓦斯赋存的分析研究,绘制了井田内瓦斯含量等值线图,并对矿井不同开采时期的瓦斯涌出量进行了预测,确定了矿井不同开采时期的瓦斯涌出等级,指出矿井开采二、三、四采区时需要进行瓦斯抽放,对矿井安全工作具有指导意义。
Based on the analysis and research on the distribution law of gas content and gas occurrence on 3# Seam,the paper drew isogram for gas content in minefield,predicted gas emission in different exploitation period of mine field,determined gas emission grade in different exploitation period of mine field and pointed out the need for gas drainage while mining in 2,3,4 Mining Area,which had guidance meaning for mine safety work.
