主　　题：mining thick optimization 

摘      要：Highwall mining of thick(up to 30.48 m)steeply dipping(20°or more)coal seams provides many chal lenges,both geotechnically and operationally,as seam dips near or in excess of highwall mining machine capabilities are *** coal recovery while maintaining highwall stability requires innovative techniques with regard to web and barrier pillar layout,depth of penetration,and choice of mining horizon within the *** of highwall mining slopes,openings,and pillarsare typically analyzed using the ARMPS-HWM program,as well as LAMODEL,UDEC and SLOPE/W *** stability can be maintained,and highwall mining production optimized by applying design cri-teria in creative ways,including alternating miner penetration depths and initiating mining of thick seams toward the bottom of the *** mining of thick,steeply dipping coal requires careful planning and execution,including close cooperation between geotechnical design engineers,the mining company,and the highwall mining *** paper describes the application of creative design techniques to a specific pit arrangement at the Westmoreland Kemmerer Mine,Kemmerer,*** mining was accomplished by UGM ADDCAR Systems,LLC on a contract basis.
