Based on the theory of thermodynamics and combustion and the study of the mechanism and application effectiveness of water-pouring method for prevention of oxidation and spontaneous combustion of residual coal in goaf, the author proposed a new and efficient technical measure for checking the spontaneous combustion in goaf.

Evaluation system of prevention and control technology for coal spontaneous combustion;

Study on the forecasting target of coal spontaneous combustion;

Research on coupling between oxygen consumption rate and temperature during coal spontaneous combustion process;

As is known, although general engineers and technicians in the coal mine practice have accumulated a lot of data and materials in this way, coal seam spontaneous combustion is still an extremely complicated physical-chemical and environmental process to be harnessed.

Mechanism and restraining technology on spontaneous combustion of coal detonating gas in goaf

Theory of gases generation during the process of spontaneous combustion of coal

In order to understand the process of coal self-ignite,the process of spontaneous combustion of coal was simulated with adiabatic oxidation, and the temperature-time curves and the rule that activation energy increases with temperature rise were obtained.

Design and development of a device for simulating coal spontaneous combustion;

Based on the study of main factors of coal spontaneous combustion,a mathematical model for the process of coal self-heating in mines was put forward.
