Determinait on of Goaf“Three Zones” Scope in Pang Zhuang Mine and Fire Prve ention Technology
XIE Zhong-peng
Abstract：According to the actual condition of the 7431 fully mechanized caving face in Pang Zhuang mine ,4 measuring points are arranged along the goaf and the gas composition in goaf is measured.With the method of cubic spline interpolation ,the width specific scope of the “three zones” in goaf and the time of the residual coal in oxidation zone are determined according to the concentration of O 2,CO.At last,the implementation process of fire prevention technology at the scene is determined according to the scope of “three zones”,which effectively prevents the spontaneous combustion of residual coal in goaf and ensures the safe extraction of the coal mining face.
