采空区火灾多元可燃气体对CH4爆炸极限的影响
Influence of multiple combustible gases on explosion limit of CH4 in goaf fires
摘要
Abstract
This paper is devoted to investigating the effects of multi-component combustible gases on the explosion limits of CH4 during goaf fires.The study involves obtaining the generation patterns of multi-component combustible gases at different temperatures through the coal programmed heating experi-ments,20 L spherical explosion parameter experiments and the goaf fire environment,analyzing the pri-mary gas components influencing CH4 explosion limits,conducting the experiments that the CH4 explosion limits are influenced by CO and H2 multi-component combustible gases,and using SPSS software to ana-lyze and fit the linear regression equations.The results show that CO is the predominant gas during the early stages of goaf fires and serves as a critical indicator for spontaneous combustion monitoring.Both CO and H2 influence the explosion limits of CH4,but the less content of H2 has more significant impact.The linear regression model established by SPSS software is in accord with statistical significant,verifying the effects of multi-component combustible gases on CH4 explosion limits.This research provides a scien-tific basis for formulating emergency response plans for goaf fires in coal mines.关键词
