Abstract:

Properties of gas coal from different coal mines are analyzed by comparing the coal qualities of similar value G and Y.Coal blending test for cokemaking is conducted to study the differences in coke properties produced from gas coal.The result shows that coal vitrinite reflectance,logarithm of fluidity degree and plastic zone of fluidity play a dominant role in hot strength of coke.Since the gas coal has high plastic mass,good fluidity and high reflectance,it can appropriately be increased during coal blending.
