针对北辰矿10煤层瓦斯赋存不明的状况,对北辰矿10煤层以往数据进行可靠性评价和分析,采用井下钻屑解吸法对煤层瓦斯含量进行补测,并用瓦斯地质法分析了影响北辰煤矿10煤层瓦斯赋存规律的地质因素。结果表明,北辰矿瓦斯呈“两端大,中间小”规律,且与埋深、构造和岩浆岩有密切关系。这对矿井通风设计及下一步的采掘部署,以及相应的瓦斯防治措施具有重要的指导意义。
In view of the unknown occurrence of gas in No.11 coal seam of Beichen Mine, the reliability evaluation and analysis of the past data of No.11 coal seam of Beichen Mine was carried out. The downhole drilling dust desorption method was used to make additional measurements on the gas content of the coal seam and the gas geological method was used to analyze the influences of Beichen Coal Mine 10 Geological factors of coal seam gas occurrence law. The results show that the gas in Beichen Mine is in the form of “big ends and middle small”, which is closely related to the depth, structure and magmatic rocks. This has important guiding significance for mine ventilation design and the next step of mining and deployment and the corresponding gas prevention and control measures.
