Application of Gas Control Technology in Adjacent Seam of Very Thin Coal Seam

摘要: 为了实现煤矿安全高效地运行，本文对近距离极薄煤层开采邻近层泄压瓦斯治理技术进行了应用研究。本文以叙永煤矿12采区首采煤层C19煤层工作面为研究对象，制定了近距离极薄煤层开采邻近层泄压瓦斯治理技术，并测量分析了高位巷瓦斯抽采数据。结果表明：采煤工作面顺层平行密钻孔抽采与高位巷钻场抽采相结合的近距离极薄煤层邻近层瓦斯治理技术是有效的，并提出了叙永矿区高位巷钻场的最佳间距优化方案，为今后煤矿瓦斯治理提供基础资料以供借鉴。

Abstract: In order to realize the safe and efficient operation of coal mine, this paper studies the application of pressure relief gas control technology in adjacent seams during the mining of very thin coal seams. In this paper, the C19 working face of the first coal seam in No.12 mining area of Xuyong Coal Mine is taken as the research object. Based on that, the pressure relief gas control technology of the adjacent seam in short-distance extremely thin coal seam mining is formulated, and the gas drainage data of high-level roadway are measured and analyzed. The results show that the tech-nology of gas control in the adjacent seam of very thin coal seam is effective, which combines par-allel and dense drilling along the seam with high-level roadway drilling, and the optimum distance between high-level Roadway Drilling Sites in Xuyong mining area is put forward, which provides basic data for future gas control in coal mine.
