Although adding a third crushing stage may add to capital expense at the onset, the higher yield and reduced wear and tear on the crushers over a sustained period may pay dividends down the road.
Equipment Beam Stage Loader and Crusher. When the coal has been hauled to the maingate, it then has to be transferred through a 90 o turn, and loaded onto the maingate conveyor. This function is carried out by the "Beam Stage Loader or BSL", which is another scraper conveyor, in this case with steel plates on both sides and runs from the maingate drive to the maingate conveyor (belt).

· Additionally, values of the coal crushing and transport energies can be enhanced by the order of 118.9–206.6% and 157.8–406.6%, respectively, thereby resulting in a stronger conveying capacity of outburst coal–gas flow along with severe coal fragmentation.
· After analyzing the coal occurrences in China, the practice and application of surface mining technology, it is proposed that the attention should be paid to the problems such as coal haulage system layout design and the reliability improvement of the system of shovel/truck/crusher in the future development of surface coal mining.
U.S. underground coal mine workers. • During 1980–2005, over $39 billion in CWP benefits were paid to underground coal miners and their families. • Recent x-ray surveillance data for 2000–2006 show an increase in CWP cases. Nearly 8% of examined underground coal miners with 25 or more years of experience were diagnosed with CWP.
After coal is mined, trucks transport it across the haul road to the coal processing facility, where it is unloaded onto an open storage coal pile at unprocessed coal and abuts a retaining wall that separates the coal pile from the crushing equipment within the coal processing facility. Near the top of the retaining wall is an apron feeder ...
Face Area Haulage. With virtually all main coal haulage systems within the seam being by conveyors which start from a more or less fixed point, some arrangement is needed to bridge the gap from the coal cutting machine to that point. For a longwall face the gap is bridged by the AFC and BSL, both of which are dealt with under longwall equipment ...
