Based on the rational utilization of coal seam in the stone upper mine field

the characteristics of coal seam B

4

and B

3

and the macroscopic characteristics of coal and rock in the Shishang mine field are introduced. Through the analysis of the micro-coal and rock characteristics and coal quality characteristics of each coal seam

the results show that the B

4

coal seam is coal with extremely low total water content

medium high ash content

medium sulfur content

low volatile content and medium high calorific value

and the coal belongs to coking coal（No. 15）. B

3

is the coal with extra low total water content

medium high ash content

medium sulfur content

medium volatile content and medium

calorific value. The coal belongs to coking coal（No. 25）. The selectivity of coal is difficult to choose

B

and B

coal seams can be used as coking coal
