基于示踪气体采空区漏风通道定性识别

The Qualitative Identification of Air Leakage Channels in Goaf Based on the Tracer Gases

根据示踪气体连续释放原理,通过确定最短采样距离、采样时间及释放量等漏风测定参数,采用新型便携式示踪气体检测仪对工作面采空区及高抽巷漏风进行考察,得出工作面漏入采空区又流出的风量及高抽巷的漏风量,此参数为矿井火灾防治提供了依据。

According to the continuous release principle of tracer gases, by determining the shortest distance of samples, the sample time and release volume and other air leakage determination parameters, the new portable tracer gas detector is adopted to inspect air leakage in the goal high lane, air flow leak from face into the goal and outflow and air leakage of the high pumping lane are got. This parameter provides a basis for mine fire control.
