摘　　要：受地质条件控制,煤与瓦斯突出的发生地点呈区域性分布,瓦斯突出区域性预测要以瓦斯地质为基础.在长虹公司地质勘探时期的瓦斯地质资料统计,以及二1煤层瓦斯基础参数测定成果的基础上,运用瓦斯地质学的研究方法总结了长虹井田二1煤层瓦斯的赋存特征和瓦斯地质规律.从瓦斯地质角度对长虹公司二1煤层煤与瓦斯的突出现象进行了分析,确定了长虹公司二1煤层煤与瓦斯突出区域预测指标及其临界值,进而将井田划为3个相互独立的瓦斯地质单元;根据瓦斯地质单元法划分突出危险区域的方法,最后对该矿的突出危险区域与非突出危险区域进行了划分.Coal and gas outburst controlled by geological factors has the characteristic of regional distribution, and outburst regional prediction must be based on gas - geology. According to statistical analysis of the gas - geology data daring geological exploration and basal parameters of Ⅱ1 coal seam in Changhong Mine, the author found the coalbed gas reserve characteristic and gas - geology rules in the region by using gas - geology research methods. By the research of coal and gas outburst mechanism of Ⅱ1 coal seam in Changhong Mine, the prediction index and critical value for coal and gas outburst area were found, and then a three independent gas geological unit was formed. Based on delineation gas - geological unit, finally coal and gas outburst risk area or not is partitioned in Changhong Mine.
