Functional model and system for PDM of tunnel drilling rigs in coal mine

It is necessary to manage product data and development process of tunnel drilling rig, which is mainly used to drill holes in coal seam for gas drainage. The requirements of product data management (PDM) for drilling rigs are defined from the perspectives of small-lot customization and variation development firstly. Then the PDM models are established, which involve project, archive, process, bill of material, component, organization and integration. The structure, composition and topology of PDM system are subsequently presented, and the PDM system is implemented with TeamCenter Express software. Finally a case of ZDY6000L is given to demonstrate the proposed model and system.
