The method to determine spontaneous combustion of coal mine goaf is explained according to the theory of static distribution of three zones.

Fuzzy comprehensive evaluation on the spontaneous combustion in goaf and its application;

Study on spontaneous combustion in Gob of fully mechanized mining with top coal caving face;

Temperature measurement system for coal spontaneous combustion experiment;

The paper introduces the application of the thermometry for the research of spontaneous ignition in Jianxin Colliery,and makes a further study on the regularity of temperature change in the goaf behind the working face in the process of advancement,which has provided the scientific basis for the colliery against the spontaneous ignition.

In addition,the time series prediction model based on BP neural network was also set up by using of forecasting indexes of goaf spontaneous ignition.

A forecast model of the coal spontaneous combustion in mine concerned the time sequences was established based on gray theory.

The paper pointed out the coal mining method in medium thick seam and thick seam having critical influences to the "one ventilation and three preventions" managements, specially the gas emission, coal spontaneous combustion and others.
