Analysis of explosion risk factor potential on coal reclaim tunnel facilities by modified analytical hierarchy process
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 ... other hydrocarbon gases, byproducts of coalification, are emitted from coal at widely varying rates and often present ventilation problems during mining. The air in some ...
Equipped with a heat reclaim ventilator and a heat exchanger (DX coil), VKM series is capable of minimizing room temperature fluctuations. VKM series maintains comfortable indoor air quality (IAQ) by adding fresh outdoor air having nearly the same temperature and humidity conditions as the indoor air. Thus, VKM ensures optimum comfort and ...

In this case, the ventilation should be adequate to avoid the build-up of a flammable atmosphere.3 For cargoes with self-heating properties, mechanical ventilation should only be applied in special circumstances. In no case shall the ventilation be directed into the body of the cargo (IMSBC Code subsection 3.5.6 and Appendix 1).

Insufficient ventilation rates within the tunnel allowed the formation of a localized atmosphere, preventing adequate dissipation and removal of methane and coal dust. The initial combustion event produced a pressure wave that traveled in both the north and south directions along the North Reclaim Tunnel.
