梅河二井煤与瓦斯突出危险性评价

Assessment on danger of coal and gas outburst in Meihe No2 Mine

依据《防治煤与瓦斯突出细则》规定的预测煤与瓦斯突出危险性指标的临界值,结合煤层瓦斯基础参数,分析指出梅河二井第三水平(+ 6 5～- 5 0m ) 12煤硬分层无煤与瓦斯突出及12煤软分层有煤与瓦斯突出危险性,为矿井防治煤与瓦斯突出提供了依据。

According to the critical value to predict the danger index of the coal and gas outburst stipulated in 'the detailed regulations to prevent and control coal and gas outburst' and in combined with the basic parameters of the seam gas,the paper analyzed and pointed out the only gas outburst in No.12 hard coal slicing and the coal and gas outburst danger in No.soft coal slicing at No3 Level (+65～50m) in Meihe No2 Mine,which could provide the references to prevent and control coal and gas outburst in coal mines.
