摘要
针对煤矿井下采空区的复杂漏风关系,应用能位测定法与示踪检测技术联合检测了孔庄煤矿井下采空区的漏风情况。通过测试计算相对总压值得出工作面采空区周围巷道漏风源和漏风汇之间的能位关系,进而定性确定了孔庄煤矿7353E\8353W工作面采空区存在的可能漏风路径。在此基础上,利用瞬时释放示踪气体法确定了孔庄煤矿7353E\8353W工作面采空区的漏风方向和漏风速度。
In view of the complex air leakage relationship of coal mine goaf, combining tracer detection technology and energy measurement,the air leakage of Kongzhuang coal mine goal. By calculating the relative total pressure, the energy relationship between air leakage origin and air leakage paths around the working face roaelway is obtained. On this basis, using the method of instantaneous release of tracer gas, the direction and speed of air leakage around 7353E／8353W working face goaf in Kongzhuang Coal Mine is determined.
