Study of inhibition characteristic of sand suspending thickener for spontaneous combustion prevention

摘要

In order to investigate the inhibition characteristics of green and environmentally friendly sand suspending thickener, we applied the self-designed Temperature Program Experiment System to test three different inhibiting substances, the calcium chloride, the soluble glass, and the sand suspending thicker, for comparison. Comparing the oxidation temperature curves of the primordial coal with the ones processed by inhibiting substances, we found that the temperatures of processed coals were all quite low and the temperature of the coal processed by sand suspending thickener the lowest. Therefore, the sand suspending thickener is the best material among the tested materials for fire-fighting in coal mine.
