06.01.2016Recently, a new type of coal auger working mechanism with five bits was used to improve coal mining efficiency [1, 2]. The five-bit coal auger is shown in Figure 1 . Due to the constraint reaction force of coal wall, gravity, cutting resistance, and friction, the vibration of the working mechanism is relatively excessive, which can cause serious drilling deflection [ 3 ].

01.01.2013Abstract. At open pit coal mines, a large amount of coal is left around the end-walls due to the stability of slope, mining boundary, and so on. In order to increase coal recovery of open pit coal mines,the application of a highwall mining system for residual coal around the end-walls is proposed. This mining method can be extracted the coals
