Various companies and researchers presented on new technology and improvements in conveying systems, including ThyssenKrupp Industrial Solutions, which presented on a patent-pending development to eliminate slope conveyor transfer points.
The DoubleBelt system, designed for slope conveyors, eliminates transfer point excavations by replacing multiple in-line flights by a single conveyor.
The industry is heading toward higher horsepower, higher capacity slope conveyor systems, explained Vince Richardson, district sales manager-conveying products for Joy Global.
system rated for 10,000 hp at 7,000 tph in the IB, which is believed to be the largest applied horsepower for any operating slope conveyor.
Today's modern longwall mines have been designed to accommodate that production capacity and the slope conveyors often have to handle production from two longwalls and multiple sections.
As little as seven years ago, slope conveyors could not easily achieve these high capacities.
Brock talks about new overland and slope conveyor systems, which have allowed the miners to seal major portions of Bailey and will allow them to eventually do the same for Enlow Fork.
The new Bailey overland and slope conveyor system allowed CONSOL Energy to seal a large portion of the mine giving it a temporary advantage over Enlow Fork.
The company has made some major capital investments recently to widen the longwall faces, develop the BMX mine, build the Training Academy, and install the overland and slope conveyors.
