Abstract: In order to solve the problem of trackless transportation of personnel, materials and equipment in vertical shaft coal mines, in view of the restricted space of vertical shaft cages and the diversified transportation needs of underground, as well as the special working conditions such as poor ventilation and high slope underground, a platform-based R&D model is proposed to first develop a clean power and transmission platform based on which the development of a series of trackless rubber wheeled vehicle. The key technologies such as the overall design of the vehicle , determination of the main parameters, development of the platform, multi-mode design of the driving unit, expansion design of the work unit and cleaner emissions, safety assurance of the vehicle are described.The articulated trackless rubber wheeled vehicles for vertical shafts applying the above key technologies and design solutions have been verified in Wangcun coal mine of Jinneng Group and Shanxi Sanyuan coal industry.The test results show that: the technical performance of vehicle fully meets the needs of the production site, and the products covers the full range of functions and highly versatile. The research on the above key technology, design ideas and methods can solve the problems of the trackless vehicles enter and exit the vertical shaft cage directly, diverse transportation needs and tailpipe pollution, poor safety protection, which can accelerate the application of trackless transportation in vertical shaft coal mines.
