露天矿爆破扬尘规律及水炮泥配比优化
Blasting-dust diffusion rule and water stemming ratio optimization for open-pit mine
摘要
Abstract
In order to reduce the pollution resulting from the blasting dust in a simple and effective way,and improve the dust suppression efficiency of water stemming for the most open-pit mine bench,the blasting dust diffusion law and the optimal ratio between water-stemming and solid stemming were studied.According to the theory of gas-solid twophase flow and explosion mechanics,and by using Fluent numerical simulation combined with field test,the real-time simulation of blasting dust pollution was realized.The analysis results show that in the impact movement stage and mushroom cloud formation stage,the blasting air rapidly expands,and a large amount of blasting dust spreads into the open air space.The dust slowly sinks,whose particle size is 60～100 μm,and the dust whose particle size under 40 μm sinks very difficultly and continues to stay in the air due to wind disturbance.The water-stemming and solid stemming ratio formula was attained,meeting the requirements of both blasting effect and the idea suppression efficiency.关键词
