Abstract
This paper has tested the CO source of 2521 fully mechanized face through SF6 gas and contrapuntally made the comprehensive control technology based on loess cover, loess isolation and grouting slurry. In fire extinguishing process, loess isolation is used to prevent spontaneous combustion area from enlarging, loess cover reduces the air leakage in the spontaneous combustion area of Coal Gangue Heaps, and borehole grouting and trenching grouting reduce heat quantity of the spontaneous combustion area. According to the detection of spontaneous combustion field parameters, above technical measures have controlled the spontaneous combustion areas of coal gangue in Baijigou Coal Mine.
