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 environment-friendly and highly effective inhibitor of spontaneous combustion of coal, and to provide basic data and theory for the efficient and safe prevention and control of spontaneous combustion in coal mines, rare earth hydrotalcites (LDHs) were prepared by coprecipitation method. Coal spontaneous combustion resistance evaluation. Experimental results show that adding 15% La-containing LDHs-2 inhibitor has the most obvious effect on the spontaneous combustion of Seinen coal.
