摘要
针对温庄煤矿,搭建了煤自燃指标气体程序升温实验台,经对比实验找出了当实验初始温度、程序升温速率、干空气流量、煤样粒度和煤样量等实验条件发生变化时,对煤自燃程序升温实验中气体产生规律造成的影响。其中,初始温度是影响气体产生规律的关键因素,煤样质量和程序升温速率次之。
Building the coal spontaneous combustion index gases programmed temperature experiment table, the paper studied the im- pact of coal gas produced laws in the temperature - programmed experiments when the experimental conditions changed, such as the ex- perimental initial temperature, temperature -programmed rate, dry air flow, coal sample size and the weight of coal sample etc. The initial temperature was regard as the critical factor, the temperature - programmed rate and the weight of coal sample took the second place.
