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

Geomatics, 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 ...

Harmonizing Social Impact Assessment in the Bioeconomy: A Cross‐Regional Fuzzy‐Delphi Approach

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The bioeconomy transition risks underrepresenting social sustainability, while existing Social Life Cycle Assessment (S‐LCA) applications remain insufficient for comparison and decision support due to heterogeneous and non‐standardized selection of social impact categories. This study proposes a cross‐regional baseline set of impact categories

Research progress of spontaneous combustion of coal containing gas under the compound disaster environment in the goaf

Meitan xuebao
The compound disasters of gas and coal spontaneous combustion have become the main disaster mode that restricts safe mine production. As the “ignition source” of gas combustion and gas explosion accidents in goaf, coal spontaneous combustion is ...
