Analysis of Spontaneous Combustion "Three Zones" in 3237 Working Face of Zhaogezhuang Mine

Abstract:

Article Preview

Geological conditions in Zhaogezhuang are complex, and seam angles change greatly. The seam angles achieve mechanization, which is a major breakthrough in the coal mining management. Therefore, the spontaneous combustion management in the working face under complicated geological conditions has also become a safety problem. The concentration of O2 and CO and temperature changes in floating coal in gob area of 3237 working face are determined and analyzed. The division scopes of spontaneous combustion “three zones” are determined. And the possibility locations easy to fire are found. It has important guiding significance to prevent spontaneous combustion.
