辛置矿2号煤层瓦斯治理技术实践

Practice of Gas Control Technology in No.2 Coal Seam of Xinzhi Coal Mine

辛置矿2号煤层瓦斯治理主要采取本煤层瓦斯顺层抽采和上隅角插管、高位裂隙钻孔抽采等上隅角瓦斯治理措施,并进一步将这些措施应用于2-109工作面和2-107工作面。工程实践结果表明,所采取的措施可有效控制煤矿2号煤层的瓦斯含量。

The gas control of No.2 coal seam in Xinzhi Coal Mine mainly adopts the gas control measures of the upper corner, such as bedding gas drainage and spile in upper corner of the coal seam and high-level fracture drilling, which have been further applied to 2-109 work face and 2-107 work face. The engineering practice shows that the adopted measures can effectively control the gas content of No.2 coal seam in the mine.
