The Exploration of Temperature Variation in Gob Area of No.8 Coal Seam in Donghuantuo Mine

摘要

The No.8 coal seam of Donghnantuo Coal Mine belongs to the second kind of spontaneous combustion coal seam and many times combustion occurred during mining. In order to understand the natural oxidation rule of the gob area and strengthen fireproofing management, the thermocouple technology was used to observe the change of temperature in 2087 working face. The basic rule of temperature variation in gob area was gotten. It was used to guide the production and good application result was obtained.
