Study on Material Input of Coal Mines Production

Abstract:

Based on the MIPS method, material input model of raw coal production was built. Taking two coal groups which were typical as investigation object, the material input coefficients of groups raw coal production were calculated. The results showed that the air input of unit raw coal was about 0.03t/t whatever it is open pit or underground mine for two groups. The water input of underground mine was slightly high above open pit mine and the average was 6.69t/t. The solid abiotic material input of open pit mine which was about 8.45t/t was far above underground mine which was about 1.36t/t. In the all full production mines of two groups, the water input proportion was biggest in unit raw coal production and the average was about 68.21%.The solid abiotic material input accounted for 31.49% while air was just about 0.3%.
