摘　　要：随着中国煤矿开采深度的不断增加,高瓦斯矿井及突出矿井的数量也在不断增多,瓦斯灾害日趋严重。矿井发生瓦斯异常涌出、煤与瓦斯突出、瓦斯爆炸等事故的一个重要原因是未能及时、准确掌握煤层瓦斯涌出规律,超前采取科学、有效的防控措施。因此,及时、准确掌握煤层瓦斯涌出规律对矿井瓦斯治理工作具有重要意义。应用单元法现场测定020203综采工作面不同区域瓦斯浓度的分布情况,准确分析综采工作面瓦斯来源,摸清瓦斯涌出规律,掌握配风量及瓦斯抽采对工作面瓦斯涌出量的影响,为山西介休义棠青云煤业有限公司今后2#煤层综采工作面瓦斯治理提供科学依据。With the continuous increase of the mining depth of coal mines in China, the number of high gas mines and outburst mines is also increasing, and the gas disaster is becoming more and more serious. An important reason for gas accidents such as abnormal gas gushing, coal and gas outburst, and gas explosion in mines is the failure to timely and accurately grasp the law of gas gushing in coal seams, and to take scientific and effective prevention and control measures in advance. Therefore, timely and accurate grasp of the law of coal seam gas gushing is of great significance to mine gas control work. By applying the unit method to measure the distribution of gas concentration in different areas of 020203 fully mechanized mining face, this paper accurately analyzed the gas source of the fully mechanized mining face, found out the gas gushing law, and grasped the effect of air distribution and gas drainage on the gas gushing of the working face, which can provide a scientific basis for the gas control of the fully mechanized working face of 2#coal seam in Jiexiu Yitang Qingyun Coal Industry Co., Ltd. of Shanxi.
