Guidelines MDG 28: Safety requirements for coal stockpiles

The coal stockpiles referred to in this guideline are of a size that require stockpile dozers to be used to facilitate handling requirements. In most cases these coal stockpiles are over a reclaiming tunnel. Coal stockpiles are either run of mine or washed product stockpiles created from the coal mining and coal washing processes. 1.4.4 Dozer

Analysis of explosion risk factor potential on coal

Sep 14, 2018· Coal reclaim tunnel. A coal reclaim tunnel is facility located underneath the coal stockpile (as illustrated in Fig. 1) that serves as a transfer point for coal from the stockpile to other areas. Coal from the stockpile will be transferred onto the conveyor belt through the feeder, and then the conveyor brings the coal to the destination, such

How to design and improve stacking and reclaiming systems

In determining coal yard design the receiving capacity and loadout capacity must be taken into account, as well as the stockpile volume where the cost/benefit ratio must be closely studied. Methods of stockpiling are described, including overhead stockpiling conveyor and reclaim tunnel, stacking tube/single discharge, longitudinal pile with

Analysis of explosion risk factor potential on coal

coal stockpiles area near the port and are equipped with a conveyor belt to transport coal continuously from stockpile to a coal barge or to a coal carrier. In coal reclaim tunnel, there is a risk of fire and explosion because the explosive methane gas and coal dust could be present in the tunnel as consequences of coal transportation operations.
