Automatic transformation and industrial test for mine tunneler
In light of the low automatic and intelligent level and low tunneling efficiency of the existing tunneler in a coal mine of Shanxi,an automatic transformation was carried out.After the transformation,the system structure of the tunneler is of key functions and cutting application program.The industrial test shows that the transformed tunneler can perform auto-matically controlled cutting and adaptable cutting.According to the cutting operational conditions,and combining the electric motor load,tunneler hydraulic system pressure and cutting motor load conditions,the swing speed of cutting arm and the running speed of supporting roller of tunneler can be automatically adjusted to realize the automatic and intelligent operation of tunneler.
