This paper puts forward main 7 issues to which should be paid attention in implementing coal-electricity integrated projects, and explains the coal conveying system and principles of its coal storage, sifting and pulverizing, and metering facility configurations.

In light of Surface Mining, System Analyzing Principle, Reliability Theory, Technical and Economic Analyzing Method, System Simulation and computer technique, the thesis aims at optimum research on coal conveying system in dragline overcast stripping system for meeting the practical needs of our country’s importing dragline stripping system.
