Abstract

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