摘　　要：为确保用瓦斯地质图划分煤层突出危险区域的准确性和有效性,提出分别以煤层埋深和测点坐标为参照,利用sufer8.0软件绘制瓦斯压力和瓦斯含量等值线图,综合评判煤层的突出危险区域和无突出危险区域。并通过此方法对开元煤矿3#煤层九采区进行了突出危险区域划分,划分结果符合现场实测情况。In order to ensure the accuracy and effectiveness of outburst risk areas division by the gas geological map. That drawing the gas pressure and gas content contour map thtough sufer8.0 are put forward,the reference value is the buried depth and coordinates of coal seam. Then divided into outburst risk areas and without risk areas with the contour map. Using the method, the No.3 coal seam nine stope of Kaiyuan mine is successful to be divided danger zone compartment of coal and gas outburst. The division result coincides with the measured data of the coal seam.
