紊流扩散和纵向弥散是两个不同的物理概念。在井巷紊流传递过程中,纵向弥散系数远远大于紊流扩散系数。紊流扩散理论是矿井空气污染防治的理论基础,这方面的进一步深入研究有可能导致新学科——矿内空气污染气象学的诞生。今后一段时期内,这方面的研究工作主要为紊流扩散系数、纵向弥散系数的确定、污染源源函数、峒室污染物的传递规律及如何利用紊流扩散理论计算通风风量等问题。
Turbulence and vertical dispersion are two different physical concepts. In the process of turbulence transfer in the tunnel, the longitudinal dispersion coefficient is far greater than the turbulent diffusion coefficient. The theory of turbulence and diffusion is the theoretical foundation for the prevention and control of mine air pollution. Further study in this area may lead to the birth of a new discipline, meteorology of mine air pollution. In the next period of time, the research work in this field mainly focuses on the problems of turbulence diffusion coefficient, vertical dispersion coefficient, source function of pollution, transfer rule of pollutants in chamber and how to calculate ventilation air volume by turbulent diffusion theory.
