摘要

研究考虑了变质程度有限的长焰煤在与基于硅酸盐水泥的混合物浸泡后表面性质的变化。所使用的钝化液是用于矿井底部灌浆的水泥溶液的滤液和悬浮液。用矿化水泥混合物处理煤炭可将表面可能被氧化的基团转化为不能被氧化的基团。煤炭表面形成的矿物层可防止氧化。结果表明，水泥悬浮液可用于减少矿井中煤炭接触面的氧化。

Deactivation of Coal Oxidation by Mixtures Based on Portland Cement

The change in surface properties of long-flame coal of limited metamorphic development on steeping with mixtures based on Portland cement is considered. The passivating liquids employed are the filtrate and suspension of cement solution used in grouting the bottom of mine workings. Treatment of coal with mineralized cement mixtures transforms surface groups that may be oxidized to groups that cannot be oxidized. The mineral layer formed on the coal surface prevents the development of oxidation. The results indicate that cement suspensions may be used to reduce the oxidation of the coal’s contact surface in mine workings.
