摘要
为了开发出新型环保高效抑制煤自燃的阻化剂,以及为煤矿高效、安全防治自燃火灾提供基础数据及理论,采用共沉淀法制备出稀土类水滑石(LDHs),通过程序升温实验对LDHs的煤自燃阻化效果进行评价。实验结果表明,添加浓度为15%含La元素的LDHs-2阻化剂对色连矿煤样自燃的阻化效果最为明显。
In order to develop a new type of environmental protection and high efficiency inhibitor of coal spontaneous combustion, to provide basic data and theory for high efficiency and safety control spontaneous combustion fire in coal mine. LDHs was prepared by co-precipitation method. The inhibiting effects of LDHs on coal spontaneous combustion was evaluated by temperature programmed experiment. The experimental results show that the inhibiting effects of LDHs-2 containing La elements with the added concentration of 15% on the spontaneous combustion of the coal sample of Selian mine is the most obvious.
