摘要
本文根据空气对流扩散理论建立了井下某一瓦斯源在巷道风流中的一维弥散方程;采用实体系示试验方法确定方程中的未知系数;按照多脉冲释放分解和迭加原理可将弥散方程的解析式推广计算一个按已知规律涌出的瓦斯源在井巷风流中的运移规律.
This paper puts forward one-dimention dispersion equation of some gas source in the tunnel airflow according to the convective diffusion thoery.The unknown coefficient of that equation is determined by the method of the tracer test in underground airflow.On the basis of multi-pulse release disintegration and superposition principle,the analytic solution of one-dimmention equation is extented to calculate gas migration in airway.This method proves feasible and practical by living examples
