Investigation into Self-burning Phenomenon of Insulating Layer of Oil Hydrolysis Pot 油脂水解罐保温层自燃现象探讨
This paper summarizes the method of preventing self-burning in goaf under difficult conditions by the study of firing mechanism and control technique of self-burning on 19th coal layer of Panxi Coal Mine, and provides a reference for the similar wells. 本文通过对潘西煤矿十九层煤自燃发火机理和防治技术的研究,总结出困难条件下预防采空区自燃的方法,供其它相似矿井参考借鉴。
Self-burning of coal seriously restricts the safety production of coal mine. 煤炭自燃严重制约着矿井的安全生产。
The separating-out regularity of indication gas during spontaneous combustion of coal was found and the proportion curve of gas concentration was drawn out by simulating the self-burning process of coal with absorption and concentrating method when coal was heated. 采用煤体加热,吸附浓缩的方法对煤炭自燃过程进行模拟,找出自燃过程中指标气体的析出规律,绘制了浓度比例曲线。
