A mine ventilation system provides a fresh air flow to the underground workings in a coal mine. Such sufficient air volume can dilute and remove noxious gases (typically NOx, SO2, CH4, CO2 and CO) and maintain a suitable working environment for coal miners. On the other hand, a poor ventilation system often leads to serious consequences such as …
The new comprehensive fire and explosion risk assessment of coal reclaim tunnel (CRT), by applying Monte Carlo simulation to address the probability distribution of risk fire and explosion factor, and the risk matrix analysis as a method to classify the total risk rating obtained from Monte Carlo simulation, has been proposed in the present research.

This study focused on developing a risk assessment method for explosion at a coal reclaim tunnel (CRT) facility. The method was developed based on an analytical hierarchy process (AHP), which is an expert system that quantifies the factors of explosion incidents, based on events and hierarchies. In this paper, the proposed model was …
