介绍了利用乙烯和乙烷乙烯比预报自燃及自燃阶段实验室及工业性试验过程及参数指标值。
It is successful to use ethylene (C_2H_4)as an indicative gas of early predicting and forecasting fire underground in mining practice at Chaili coal mine, Zaczhung coal Bureau in Shandong province. In order to improve the technology and satisfy requiments of mining pracrice, research group made experiments on heating different kinds of coal and got mutual relation between the ratio of C_2H_6 to C_2H_4 and temperature. Results was checked in practice. Based on the ratio of C_2H_6/C_2H_4 mainly and contents of C_2H_4, C_3H_6 and C_4H_6 secondly, forecafting three phases of fire underground including long term forecasting, middle term forecasting and emergency forecasting can be made.
