Experimental Study on Influence of Oxygen Flow upon Physical Oxygen Absorption of Coal

Cai Zheng-we

Abstract

The spontaneous combustion process of coal was analyzed,experimental study was made on the physical absorption oxygen of coal samples taken from 1115(1)working face in Guqiao Mine at different oxygen flow by using ZRJ-1 coal spontaneous combustion tendency determinator,the optimum oxygen flow of the physical absorption oxygen of coal at the same ambient temperature was obtained,and thus the most suitable absorption oxygen flow for coal spontaneous combustion determination experiments can be determined.
