Large-scale sand-gravel aggregate mines often produce a large amount of dust in the process of blasting mining,which has a large concentration and a wide coverage area,which is not only not conducive to the health of workers,but also seriously affects the mine ecology.In order to realize green mining in mines,researchers conducted in-depth and step-by-step research on blasting dust control,environmental monitoring and slope greening according to dust control standards,calculated the dust quantity and concentration through theoretical models,drew the time-history curve of dust concentration,put forward key dust control measures and protection schemes,and completed environmental monitoring measures,which effectively realized blasting dust control in large-scale open-pit limestone mines,providing reference for green mining in similar large-scale open-pit mines.
