摘要
高位巷瓦斯抽釆效果较好,对治理瓦斯起到了关键的作用,但由于抽采混合量较大,对采空区的整体漏风影响较大。对此,以小庄矿井40201综放工作面为研究对象,通过对工作面在高位瓦斯抽放条件下采空区"三带"的测定,分析了其分布规律,对矿井防灭火和瓦斯治理具有重要意义。
The high-level gas drainage effect is good,which plays a key role in gas control. However,the large amount of gas extraction has great impact on the overall air leakage of goaf. Taking No. 40201 fully-mechanized caving face as the study object,by determination of 'Three-Zone'in the goaf under the condition of high-level gas drainage,the distribution regularity of 'Three-Zone'was analyzed,which has important significance for mine fire prevention and gas control.
