【摘要】 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。更多还原

【Abstract】 Turbulent diffusion and longitudinal dispersion are two different physical concepts. In mine mass transfer the longitudinal dispersion coefficient is by far greater than the turbulent diffusion coefficient. The Turbulent diffusion theory lays the theoretical foundation for prevention and control of mine air pollution. Further study in this aspect may lead to the birth of a new discipline——mine air pollution of meteorology. The research projects in this aspect in the coming period will mainly be, determination of turbulent diffusion coefficient and longitudinal dispersion coefficient, pollution source function, rules of chamber contaminant mass transfer and how to calculate air quantity by using turbulent diffusion theory.更多还原
