为了查明山阳煤矿1501面的瓦斯赋存规律及其控制因素,采用瓦斯含量直接测定法井下实测了1501面瓦斯含量,利用实测数据结合相关资料绘制了1501面瓦斯含量等值线图,并结合实际情况得出了1501面“Ⅰ区域高,Ⅱ区域低,皮带巷一侧高,轨道巷一侧低”的瓦斯赋存规律。在此基础上,研究分析地质因素对1501面的瓦斯赋存控制作用,得出煤层厚度和水文地质条件是影响1501面瓦斯赋存差异的主要控制因素。研究结论可以对1501面回采期间瓦斯治理提供理论指导。

To find out the gas occurrence regularity and its controlling factors of 1501 working face in Shanyang coal mine,the gas-content direct mensuration is adopted to measure the gas content of 1501 working face.We draw the gas content contour map of 1501 working face based on the measured and related data.Combined with actual situation,we obtain the gas occurrence regularity of 1501 working face which is“Ⅰregion is high and Ⅱ region is low,the side of belt lane is high and the side of track lane is low”.By analysing the geological factors'control action of gas occurrence on 1501 working face,it is concluded that the thickness of the coal seam and the hydro-geological conditions are the main controlling factors that influence thegas occurrence differencesof 1501 working face.The conclusions of the study can provide theoretical guidance for gas control during the mining period of 1501 working face.
