Coal top detection by conductively guided .

Coal top detection by conductively guided borehole radar wave imaging for open cut blast‐hole drilling | Earthdoc ABSTRACT Damage to the top of coal seams, caused by incorrect blast stand‐off distances, results in coal losses of up to 10–15% to the Australian open cut coal mining operations. This is a serious issue to be addressed.

Quantitative detection of settled coal dust over .

This study presents a practical implementation of field spectroscopy as a quantitative tool to detect settled coal dust over green canopy in free/open environment. Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, and pulverizing of coal. Since the inelastic nature of coal, coal dust can be created during transportation, or by mechanically handling coal ...

Coal-seam fire - Wikipedia

A coal-seam fire is a natural burning of an outcrop or underground coal seam.Most coal-seam fires exhibit smoldering combustion, particularly underground coal-seam fires, because of limited atmospheric oxygen availability. Coal-seam fire instances on Earth date back several million years. Due to fine thermal insulation and the avoidance of rain/snow extinguishment by the crust, underground ...
