Assessment of gas and dust explosion in coal mines by ...

Nov 01, 2018  A coal dust explosion is caused by a mixture of concentrations of coal dust and air that reaches the explosion limit and meets a high-temperature fire source. These two factors are taken as intermediate events of a fault tree, to conduct a further analysis and determine the various factors that influence the occurrences of such events.

Hazard and Operability (HAZOP) Studies

A HAZOP study identifies hazards and operability problems. The concept involves investigating how the plant might deviate from the design intent. If, in the process of identifying problems during a HAZOP study, a solution becomes apparent, it is recorded as part of the HAZOP result; however, care must be taken to avoid trying to find solutions ...
