A methodology for evaluation of explosion risk in underground coal mines
Research Areas
  • Engineering,
  • Mining operation
The key objective of this paper is the development of a risk assessment tool for underground coal mines based on a simplified semi-quantitative estimation and assessment method. In order to determine the risk of explosion of any work process or activity in underground coal mines it is necessary to assess the risk. The proposed method is based on a risk index obtained as a product of three factors: frequency of each individual scenario Pucm, associated severity consequences Cucm and exposure time to explosive atmospheres Eucm. The influence of exposure time is usually not taken into account up to now. Moreover, the exposure to explosive atmospheres may affect factors of hazardous event probability as much as its consequences. There are many definitions of exposure to explosive atmospheres but in case of underground coal mines the exposure is defined as frequency risk of firedamp and coal dust. The risk estimation and risk assessment are based on the developed of risk matrix. The proposed methodology allows not only the estimation of the explosion risk but also gives an approach to decide if the proposal investment is well-justified or not in order to improve safety.
