采煤机控制系统的发展

Abstractcoal is China's main energy and an important strategic resource,is the developmentof the national economy and social progress indispensable material base for themodernization of our country,coal mine,the coal resources mining efficiency related tosustainable economic development,which in turn and China Coal Mine Electrical andmechanical changes directly related to the level of.In our country modernization coalmine will always high yield and high efficiency as the first priority,the productionpractice experience shows,coal production only implement comprehensivemechanization to achieve efficient and safe mining an effective way.With the coalproduction is directly related to the work surface supporting the mining machine andother key equipment,electrical,mechanical,hydraulic pressure is provided by multipleindependent system structure,system structure is more complicated.Shearer electriccontrol system of coal mining machine cutting coal is in the process of implementing thecontrol center,electrical control system 's performance with coal production andefficiency are direct and relevant,relations with the major problem of economic benefits.But as a result of coal mining machine in underground working environment very harsh,increase mining machine control system automation realization difficulty,more hinderedthe new technology in coal mining machine system application.Key words:coal mining machine;control system;the development of
