Theory Research and Simulation of Blasting Dusts Diffusion in Underground Stope

摘要：

Controlling the proliferation of the blasting dust is an effective measure to reduce the concentration of mining dust. Through the research and analysis of the underground blasting-dusts characteristics, the calculation method of initial concentration was given. Basic model of blasting-dusts diffusion was established. The CFD simulation software CFX was used to calculate the behavior of blasting--dust during ventilation process in Tonglvshun. The relation between consistency of harmful dust and the time was exhibited visualized, Further more, the way of field measure which is difficult, low insecurity, high cost and so on is solved.
