SF_6示踪气体测定漏风技术在王庄矿的应用

SF_6 determination of trace gas leakage technology application in Wang Zhuang coal mine

利用SF_6示踪气体可以有效的测试矿井漏风通道,确定工作面向采空区的漏风方向及漏风量。结合王庄矿8103工作面的实际情况为背景,进行了现场SF_6示踪气体测试研究。研究表明:工作面全程向采空区漏风,自下隅角至上隅角漏风量逐渐减少且大致呈线性分布;8103工作面往采空区总漏风460m^3/min,占工作面总风量的20.7%。

Using SF6 tracer gas can effectively test the mine air leakage channel, determine the working face of the air leakage direction and the amount of air leakage. Combined with Wangzhuang mine 8103 working face of the actual situation as the background, carried out on-site SF6 tracer gas test research. The results show that the air leakage from working face to mined area decreases gradually from bottom corner to upper comer, and the air leakage from 8103 working face to goaf is 460 m^3/min, accounting for 20.7% of the total airflow at the working face..
