Comprehensive risk evaluation of coal spontaneous combustion in goafs based on systems-theoretic accident model and processes

open access: yesGeomatics, Natural Hazards & Risk, 2020
The traditional risk evaluation of coal spontaneous combustion in goafs in China is unilateral and inaccurate, which can be attributed to the fact that only the change in coal properties is considered and the external environment of coal is ignored ...
