The stability study on coal spontaneous combustion tendency sample
XING Xiu-yun
Abstract：For 3 types of coal spontaneous combustion tendency samples,the stability in long term of both using regular packaging method and deoxidation packaging method was researched,the effect of oxidation on the adsorbed oxygen content of coal sample was evaluated,in conclusion,normal packaging storage method was selected finally.The stability period of adsorbed oxygen content value of regular packaging samples could reach more than one year.It provided the technical basis for feasibility of the reference material of coal spontaneous combustion tendency.
