Japan1987The year continuously develops to succeed various series alternate current of the MCLEDR which mow electrical engineering to lengthways set outs to lead to adopt coal machine behind and developped to cut many electrical engineering alternate currents of mow the electrical engineering horizontal decorations to lead to adopt coal machine again for the last few the coal machine has tiny machine work condition a monitor and breaks down diagnosis system, can the numerical manifestation lead speed, roller position, stay a bottom coal thickness, electrical engineering load and everywhere temperature, have wireless remote control, and can add infrared ray shoot the machine manipulate a liquid to press a support. Poland the KOMAG mine for minerals a mechanization research centerPoland continuously developped KSE in developping successful KSE a 344 thin coal seam alternate currents with Chinese cooperation to lead foundation of adopt the coal machine a 360, KSE a 700, KSE one 800 RWs/2 BPs, KSE a 535 Ss/2 BPs, KSE1000 type etc. alternate current lead to adopt coal the coal machine cuts deeply from 630171111 raise 8001000 mms.
