While containing less sulfur, PRB coal contains more water, generates less heat and burns less efficiently than the type of coal it replaced. In fact, though overall emissions have been reduced, the plant now requires more through-put to ensure the same generating capacity. Even more vexing, due to several of the inherent properties of PRB coal, it is prone to sudden, spontaneous combustion.

The present invention discloses methods to reduce dusting in bulk materials, such as coal. The method includes mixing with the bulk material either a fraction of the bulk material having an electrostatic charge opposite that of the remainder of the bulk material or a heterologous charge control agent having an electrostatic charge opposite that of the bulk material.

The Powder River Basin is the largest coal mining region in the United States, but most of the coal is buried too deeply to be economically accessible. The Powder River Basin coal beds are shaped like elongated bowls and as mines expand from east to west in the Powder River Basin, they will be going "down the sides of the bowl".
