Airborne coal dust is also explosive, given the right particle size, concentration, and ignition source. Bureau of Mines studies have shown that ignitable airborne coal dust concentrations start on the order of 50g/m3 (0.05 oz./ft3) [5,6]. The most explosive coal dust size in air is below 75 nm (—200 mesh) [5,6].
Primary crushing happens when we take big rocks, even ones bigger than a meter, and make them into smaller bits. These bits are often between 150 and 200 mm. This step is very important. It makes the rocks smaller. This helps the next machines work better at crushing or grinding them.

This paper develops two optimal control models for the energy management of a mining crushing process based on jaw crushers. The performance index for both models is defined as the energy cost to be minimized by accounting for the time-of-use electricity tariff. The first model is referred to as a variable load-based optimal control with …
The last work on the battle was Lumir Buresh's October 25th and the Battle of Mine Creek, published in 1977 and now out-of-print. This book is part of the History Press's campaign to publish a book on seemingly every aspect of the Civil War as part of its Sesquicentenial Series, and it is, unfortunately, one of the weaker efforts.
