该论文针对我国薄煤层瓦斯抽放的难题，以玉舍煤矿为研究对象，通过研究该矿的瓦斯地质资料、煤层瓦斯涌出量等，分析了该矿采空区倾斜方向、走向方向以及法向方向的三维瓦斯运移规律，掌握了该矿的瓦斯赋存规律；以采空区瓦斯赋存“O”圈理论为基础，通过在采空区分别向工作面采空区施工4个不同角度的穿层钻孔，研究得到采空区冒落带最大高度在6~12m，裂隙带最大高度在30m左右；在此基础上建立了该矿瓦斯涌出规律模型，能够较准确的该矿井的瓦斯涌出规律进行预测。 文章最后针对NZ-702工作面的瓦斯抽放系统的瓦斯赋存、运移及涌出规律进行研究，通过对采用顺层钻孔抽放、穿层钻孔抽放以及穿层和顺层钻孔结合抽放等三种方法进行比较，确定了该矿以综合抽放为主的瓦斯抽放系统，通过对抽放率、抽放量进行预测，该方法能够满足该矿安全生产需要。

The thesis is aimed at the problems of thin coal seam Gas Drainage, Yushe mine as the research object, by studying the mine gas geological data, coal seam gas emission, etc., analysis of the three-dimensional gas migration law of the mine gob tilt direction, haed direction and normal direction, master of the gas deposit law of the mine. Based on the gob gas deposit "O" ring theory, by the gob respectively construct 4 different angles drilling hole to faces gob, the research obtained the maximum height of gob caving zone between the 6 ~ 12m, the maximum height of fractured zone is about 30m; On this basis, established the gas emission law model of the mine to be more accurate prediction of gas emission rules for the mine. Finally, the paper researches the gas occurrence, migration and emission law of the gas drainage system of the NZ-702 face, by comparing the three methods of the bedding drainage, drainage crossing and wear layer combined with cis drainage holes, determined the mine based integrated gas drainage system, through the drainage rate, drainage volume forecast, this method can meet the needs of mine safety.
