With the development of mechanized mining technology, as the main transportation equipment, mechanized coal mining belt conveyor was widely applied. Under the condition of big traffic volume, fuselage stringers determined the length of the length of transported distance. By analyzing production cycle, quality, safety and efficiency of several aspects, etc. of the belt longitudinal beam in the production, process equipment design was improved. Practice proved that the innovation of the belt conveyor production provided the precious experience for the belt conveyor production and improved economic benefit.
