Infrared diffuse reflectance spectral signature of spontaneous combustion coal;

The micro structure analysis of the spontaneous combustion coal in oxidization and inhibition at low temperature;

The occurrences of the spontaneous ignition of the comprehensive mining coal face at the spontaneous combustion coal-seam under a special condition from the 1301 face in Gengcun coal mine has been analysed.

This paper analyses the reasons for the gob fire of the face with fully mechanized mining caving method in free burning seam and gives the gob fire eradication means.

The origin and effusing pattern of gas at fully mechanized face with caving of roof coal in the inflammable coal seam,spile-drainage methods in mined area were introduced briefly,the experiences can be used for reference for gas drainage in the similar condition.

This paper studies economy analysis index system of burning blended coal of fire resistant coal from Viet Nam and free-burning coal from Tashan of China or Indonesia on 600 MW super critical unit.
