“极薄煤层采煤机械化”是四川省科委“七五”科技攻关项目。重庆大学于1985年承担了该课题的研究工作。我们在设计极薄煤层爬底板端面截割采煤机时,采用了两台串激直流电动机分别为无链牵引的驱动方式。
“Very thin coal seam mechanization” is the Sichuan Provincial Science and Technology Commission “Seventh Five-Year” scientific and technological projects. Chongqing University in 1985 assumed the task of research. When designing a shearer with a very thin seam crawler floor end face, we used two series-wound DC motors, one for chain-less traction.
