摘要
为提高瓦斯抽放效果,降低瓦斯抽放成本,针对高位钻场抽放等瓦斯抽放方法的不足,以朱庄煤矿Ⅲ6210工作面的瓦斯治理为例,进行了"顶板近水平大直径长钻孔瓦斯抽放"的试验研究,并设计了钻场和钻孔的施工参数,通过实践效果检验发现,采用该方法抽放Ⅲ6210工作面瓦斯,可减少工作面频繁通过高位钻场次数和采掘工作量,在经济效益、社会效益和安全效益上取得显著效果.
To enhance the effect and reduce the cost of gas drainage,and aimed at the shortage of gas drainage method such as high drilling field Drainage,this paper takes the gas control of Ⅲ 6210 Face zhuzhuang coal mine for example and conducts the gas drainage with approximate level and large diameter and long drilling hole experimental studies.The construction parameters of drill field and drill hole were designed and optimized.The results of practical in Ⅲ 6210 Face showed that:The gas transfinite in working face and upper corner was eliminated,the mining speed and production was increased,the cost of mining was decreased,the economic benefit and safety benefit and social benefit was significant,.The method of gas drainage with approximate level and large diameter and long drilling hole is worthy to be widely extended.
