利用阻化剂防止褐煤矿井自然发火试验成功以后,又相继在国内一些烟煤矿井开始试用,也取得了一定的效果。现将了解到部分矿井在利用阻化剂防灭火方面的情况介绍如下,以供参考。 After using the retardant to prevent the natural fire test of lignite coal mine successfully, some coal briquette coal mines in succession have been put into trial one after another, and some achievements have been made. It will now be understood that some of the mines in the use of anti-fire retardant agent is described below, for reference.
