Tow coal samples from China and two coal samples from Australia were made for the coal type, gas velocity, temperature and other factors of the coals influenced to the formation law of the NO_x pioneer materials ( HCN and NH_(3)) from the coal pyrolysis. The results showed the contents of the volatile matter and the pyrolysis temperature are the main factors influenced to the formation of HCN and NH_(3). I the coal ranks are the same, the tendency of the pioneer material formatted in coal from the north earth and south earth are not fully the same. The higher of the coal pyrolysis temperature, the higher HCN and NH~(3) will be formatted. The formation quantity of the HCN and NH_(3) are depended on the reaction in certain period with the volatile matter and coke.
