Based On Simulate Test To Research The Law Of Co Newly Generated When External Oxygen Involved During The Coal Breaking Process

This paper carried out two different simulate tests under two different scenarios, simulated the process of cutting and crushing coal, the one is in air scenarios and the other is in nitrogen atmosphere scenarios, measuring the difference of gas composition during the process, the purpose is further demonstrate whether to produce new CO and clarify the proportion of CO new generated when external oxygen involved in the all process of cutting and breaking coal. The Coal sample used in experiments is brown coal from 6-3B fully mechanized caving face of feng shui mine Ping hang. The result show that there is new generate of CO from oxidation reaction during all the process of cutting and breaking coal in normal condition of production, the amount of CO newly generated when external oxygen involved is 23.27% of all the CO emission quantity from the total process of cutting and breaking coal. Pointed out the ratio of CO newly generated when external oxygen involved is different, because of the conditions of cutting and breaking coal in normal condition and the Coal types are different, proposed the direction of further research on mechanism of CO emission and newly generated during all the coal breaking process.
