Coal product moisture control using stockpiles

Oct 22, 2016Product stockpiles are often used as a control measure to regulate the moisture content of the coal by gravity drainage and evaporation. An understanding of the mechanisms of water migration and retention in coal stockpiles are required to optimise the management of these stockpiles.

Bulk density of coal — Monash University

The effects of the dimensionless numbers resulting from dimensional analysis on the packing density of a coal heap have been experimentally examined and analysed. Based on the experimental results, equations have been formulated for the estimation of the bulk density of a coal stockpile.

Coal face and stockpile ash analyser for the coal mining industry

Sep 01, 2001When the ash content of coal is measured on the coal face or in coal stockpiles, portable instruments are needed and they must be light. This means that high activity sources requiring heavy shielding cannot be used for such applications and new nucleonic instruments employing low activity sources must be developed.

Stockpile Height

Feb 20, 2008Coal stockpile hight. The maximum height will depend on quality of coal (% of volatiles) and duration of coal remaining in the stockpile. If coal is going to be used within a month of its receipt at plant site, you can increase the stockpile height from present 9.5 m to 12 m. I am assuming that this is a new project or yor existing stacker
