Abstract: After coal seam mining, the residual coal is soaked with the accumulated water in goaf, and its spontaneous combustion characteristics were changed after air-dried. To study the reoxidation characteristics of soaked and ...

Abstract: In this report, the influence of pre-oxidation degree and ventilation flow on the parameters of spontaneous combustion of coal (temperature, gas concentration, and exothermic intensity) was studied in six sets of programed ...
