Abstract: Based on the analysis of the stable operation condition of mine trackless rubber wheels vehicle running on the large slope roadway, the paper proposed the basic necessary condition of the trackless rubber wheels safety running on the large slope roadway. To suffice for the requirement of vehicle running on slope, the performance requirements of the vehicle in terms of load balance, traction balance distribution, vehicle braking system and heat dissipation of each system are described. This paper introduces the safety operation measures for trackless vehicles in steep shaft.
