Abstract
At present, many coal mines in underground coal loading method are: first we will fill with the first tramcar, and then push the tramcar to another one. Finally, the electric locomotive will take all tramcar away. This method has brought many problems: the demand of roadway widened, the transmission efficiency is low, the transmission of high cost, labor intensive. To resolve these problems, we put forward a kind of application in underground coal mine machinery--horizontal extension transfer machine. This article describes the loader part of the structure and working principle. Green design principles, to provide a theoretical basis for the design of similar machinery. There are many advantages of the structure in the machine, such as compact, simple operation, easy maintenance, low costly and environmental.
