硫化矿床内因火灾灭火试验研究

TEST TO DISTINGUISH SPONTANEOUS FIRE IN SULPHIDE MINERAL MINE

本文通过对硫化矿石内因火灾灭火方法的选择 ,指出了用钙质胶凝阻燃液防灭火的优越性 ,提出了阻燃液灭火相关参数的计算公式 ;采用试验研究的阻燃剂和自行研制的内因火灾喷淋灭火机进行现场试验 ,有效地扑灭了井下硫化矿石火灾 ,取得了显著的经济效益和社会效益。

Based on analysis of different fire\|distinguishing means,the paper describes the advantage of calcareous gelatinious flame\|retardant agent,gives out the formula of calculating relevant parameters when using this agent.The agent and self\|made sprayer have been successfully tested on site and achieved good social and economical profit.
