摘要
矿井采空区漏风量小,当需要定量检测漏风量时,可采用示踪气体连续定量释放法,该方法原理简单,操作简便,释放量小,检测精度高,可以定量分析漏风情况。为准确测定漏风量,需对示踪气体释放量、释放点和采样点的位置等参数进行准确计算,并对实验分析条件有较高的要求。本文对此进行了深入的分析,并结合现场进行了漏风实测,取得了良好的效果。
Tracing-gas must be released quantitatively and continuously for measuring air-leakage quantitatively, because of the lower air-leakage in gob area. This method is simple in theory and operation, and high detecting accuracy and less releasing gas for analyze air-leakage quantitatively. Releasing rate, releasing points and sampling points must be ascertained accurately, and it required higher lab conditions for air-leakage determination. This paper analyzed the method deeply and determined in local with good results.
