煤矿自燃引起的火灾严重威胁着矿井财产和人员安全。为了有效地降低井下发生火灾的概率,提高煤矿开发安全度,利用阻化剂来达到防火目的很有必要。文章深入分析了煤炭自燃的原因和条件,研究了阻化剂发挥防火作用的化学和物理原理,使用煤样进行一系列阻化实验,通过程序升温氧化法来分析不同阻化剂质量分数、温度条件下对煤样自燃防止作用产生的影响,确定最佳阻化剂质量分数,为煤矿安全生产提供有效借鉴。
Coal spontaneous combustion caused a serious threat to the mine property and staff safety. In order to effectively reduce the probability of occurrence of fire underground and improve the safety of coal mine development, the use of retardant to achieve the purpose of fire prevention is necessary. In this paper, the causes and conditions of spontaneous combustion of coal are analyzed in depth. The chemical and physical principles of the flame retardants are studied. A series of resistance experiments are conducted using coal samples. The temperature, Conditions on the self-ignition of coal samples to prevent the impact of the role, to determine the best mass fraction of the inhibitor, to provide an effective reference for mine safety in production.
