The existing buffer capacity of the original coal bunker in Jinjie Coal Preparation plant is only 8 hours,which leads to the contradiction between underground and surface production organization coordination.After the addition of No.4 original coal bunker with the diameter of 30 m,the buffer capacity of raw coal is increased by 28 000 tons.Thus the original coal bunker can maintain high material level operation,reduce the drop of raw coal into the warehouse,and improve the lump coal production rate,which can increase 540 000 tons of lump coal every year.About 1 million tons will be added each year to further explore the value of products.At the same time,after adding classification equipment to No.3 original coal bunker,-40 mm final coal will be supplied to Beiyuan Chemical and Shenmu Chemical Industry,and+40 mm lump coal will be returned to the coal preparation plant for washing and processing as products for sale,with significant economic bene-fits.
