摘　　要：针对正利煤业4号煤层瓦斯赋存不明确等问题,测定了煤层的瓦斯含量,得出瓦斯随着埋深的增加而增大,煤层最大埋深为490m,瓦斯含量为3.8m^3/t,确定了4号煤层瓦斯分带属甲烷带、氮气甲烷带,对4号煤层开采时的瓦斯预防提供了理论基础。In view of the unclear gas occurrence in No.4 coal seam of Zhengli Coal Industry,the gas content in the coal seam was measured.It was found that the gas increased with the increase of the burial depth.The maximum burial depth of the coal seam was 490m,and the gas content was 3.8m^3/t.It was determined that No.4 coal seam was divided into methane zone and nitrogen methane zone,which provided a theoretical basis for the gas prevention during the mining of No.4 coal seam.
