山脚树煤矿矿井上下联合瓦斯治理技术研究OA
Research on upper and lower combined gas control technology in Shanjiaoshu Coal Mine
瓦斯对煤矿安全生产产生了巨大威胁,为了实现煤矿安全高效生产和资源的高效利用,结合贵州山脚树煤矿221015工作面的具体情况,采用井上下联合瓦斯治理技术,分析研究井上下联合瓦斯治理的效果.实践结果表明,地面钻井抽采瓦斯浓度可以稳定在90％以上,井下瓦斯抽采浓度平均可达30％,且地面钻井抽采可以提高井下抽采的效果,保障了山脚树煤矿的安全高效生产.
Gas poses a great threat to coal mine safety production.In order to realize the safe and efficient production of coal mine and the efficient utilization of resources,combined with the specific situation of 221015 working face of Shanjiaoshu Coal Mine in Guizhou,the combined gas control technology is used to analyze and study the effect of combined gas control.The practical results show that the gas concentration of surface drilling extraction can be stabilized at more than 90％,and the average concentration of underground gas extraction can reach 30％.Moreover,surface drilling extraction can improve the effect of underground extraction and ensure the safe and efficient production of Shanjiaoshu Coal Mine.
