The Recent Technological Development of Intelligent Mining in China

Jinhua Wang,Zenghua Huang

Engineering 2017, Volume 3, Issue 4, Pages 439-444 doi: 10.1016/J.ENG.2017.04.003

Abstract:

In the last five years, China has seen the technological development of intelligent mining and theon the work face.With these technologies, the number of miners on the work face can now be significantly reduced.Miners are only required to monitor mining machines on the roadway or at the surface control center,since intelligent mining can be applied to extract middle-thick or thick coal seams.

Robotized machining of big work pieces: Localization of supporting heads

Wojciech SZYNKIEWICZ, Teresa ZIELIŃSKA, Włodzimierz KASPRZAK

Frontiers of Mechanical Engineering 2010, Volume 5, Issue 4, Pages 357-369 doi: 10.1007/s11465-010-0103-0

Abstract: A planner for a self adaptable and reconfigurable fixture system is proposed. The system is composed of mobile support agents that support thin sheet metal parts to minimize part dimensional deformation during drilling and milling operations. Compliant sheet metal parts are widely used in various manufacturing processes including automotive and aerospace industries. The main role of the planner is to generate an admissible plan of relocation of the mobile agents. It has to find the admissible locations for the supporting heads that provide continuous support in close proximity to the tool and trajectories of the mobile bases characterized by very high speeds during the relocation phases.
