7. ROADWAY DEVELOPMENT R&D STRATEGY - 04/07 • Following the March 2007 Roadway Development Workshops the RDTG developed a Roadway Development R&D strategy based upon input given by participants at those Workshops ACARP Project C15005

8. ROADWAY DEVELOPMENT R&D STRATEGY - 04/07 • Immediate (1 year project) • “project management” systems for roadway development (including maintenance) • “fundamentals of roadway development” handbook • process model for development • management structure, style and skills; • functional specification for “CM 2010” • Medium term (2-4 years) - “CM 2010 project” (similar to LW project) • components that can be retrofitted to current generation machines • automated bolting system • alternate skin reinforcement and rib confinement • services • Longer term (+5 years) - “continuous mining system” • integrated system incorporating cutting, loading, conveying, support, and logistics flowing on from CM 2010 project ACARP Project C15005

9. KEY ELEMENTS - CM2010 R&D STRATEGY • Later in 2007 we attempted to develop a model which demonstrated the relationship between key elements of the CM2010 R&D strategy as it became known as ACARP Project C15005

10. ACARP FUNDING 2008 • Pleasing to advise that a number of roadway development related R&D projects have been funded by ACARP commencing 2008 following recommendations made by the RDTG, including development of: • A polymer based alternative skin reinforcement and confinement system - to eliminate the installation of steel mesh and, in conjunction with SDB, allow operators to be removed from the immediate face area while improving roadway development performance • An automated system for installing SDB and mesh, including an integrated logistics and materials handling system from the supplier to the face - to similarly remove operators from the immediate face and improve roadway development performance • A simulation model to enable the limitations of current development processes to be understood, and to evaluate potential roadway development technologies and practices before committing scarce resources to pursue development and/or conduct field trials • A handbook to capture the industry’s current “body of knowledge” of roadway development practice for future generations ACARP Project C15005

11. CM2010 R&D STRATEGY - MARCH 2008 • The RDTG has continued to develop the CM2010 R&D strategy to provide the framework for an integrated approach to developing a new generation high capacity roadway development system • Now like to share the strategy with you and invite your review and critique ACARP Project C15005

12. KEY STRATEGIES – CM2010 • Develop “self-steering” technologies and systems that enables mining equipment to mine roadways in accordance with predetermined survey controls and to maintain both azimuth, horizon and grade control within a variable seam horizon, and to totally automate the cutting and loading cycle (including mining breakaways) thus enabling equipment to be remotely supervised • Will require a combination of fundamental and applied research building upon Highwall Mining and Longwall Automation technologies • CSIRO Queensland Centre for Advanced Technologies has demonstrated capabilities • Key R&D element over next 2-3 years ACARP Project C15005

13. KEY STRATEGIES – CM2010 • Develop technologies and systems that enables face services to be extended within the 3 minute cut, load support cycle and without direct operator involvement • One monorail system currently being reinstalled at Mandalong with recent orders placed for 2 new monorail systems • Expected to be largely driven by mine sites, with support from and feedback to RDTG • Will predominantly require operational improvement to apply existing technologies with some applied research required to automate installation of monorails and integrate into a remotely supervised, high capacity mining system ACARP Project C15005

14. KEY STRATEGIES – CM2010 • Develop systems that enables the automated installation of conventional resin anchored bolts and self drilling bolts, and to feed bolts and mesh to the installation hardware without direct operator involvement • Will require a combination of fundamental and applied research • UOW recently awarded ACARP funding to pursue this initiative • Joy have prototype carousel bolter and Sandvik have operational carousel bolters (metaliferous sector) that could provide basic equipment platform, whilst CSIRO has developed a range of technologies for the ACBM that could potentially be applied • Key R&D element over next 2-3 years ACARP Project C15005

17. KEY STRATEGIES – CM2010 • Develop technologies and systems that enables panel services to be advanced on a continuous basis in parallel with mining operations or alternatively, within scheduled maintenance windows • Expected to be largely driven by mine sites, with support from and feedback to RDTG • May require some applied research to develop extensible conveyors and integrate major services (H/T power reticulation, transformers, etc) into a services management system • May also require some applied research to develop more efficient mine compliant services (eg; pipework) ACARP Project C15005

18. KEY STRATEGIES – CM2010 • Develop mine logistics systems that enables mining and maintenance supplies and consumables to be delivered to the immediate mining area at a rate consistent with a 3 minute cut, load support cycle. • Logistics systems should similarly enable materials and equipment required for panel infrastructure and services to be delivered to the mining area at a rate consistent with a 200 m per day advance rate • Expected to be largely driven by the yet to be determined design of the primary mining equipment, and mine specific parameters • Therefore expected to be driven by mine sites, with support from and feedback to RDTG • May require some applied research to develop a mechanised, extensible supply system, and for overall system integration • Expected to draw upon logistics systems expertise from other industries ACARP Project C15005

19. KEY STRATEGIES – CM2010 • Develop technologies and systems that enables high speed haulage roadways to be constructed and maintained without impacting the continuity of face operations • Expected to draw upon roadway and pavement construction and maintenance expertise from other industries • Expected to be largely driven by mine sites, with support from and feedback to RDTG ACARP Project C15005

20. KEY STRATEGIES – CM2010 • Develop strategies to improve engineering availability of equipment and enable equipment to operate at design rates (10 MPOH) for 20 or more hours per day • Expected to be largely driven by mine sites with strong support from OEM sector • Industry wide coordination will be necessary to improve overall engineering competency standards across the industry and to ensure industry wide standards are developed and adopted. Hence anticipate continuing support from and feedback to RDTG ACARP Project C15005

21. KEY STRATEGIES – CM2010 • Develop pre-mining systems, including gas drainage, seam dewatering, and the detection and pre-treatment of faults and other geological anomalies, to enable a safe, compliant and productive mining environment to be maintained • Expected to include a combination of fundamental and applied research, together with a major operational improvement component at a mine site level • CSIRO Queensland Centre for Advanced Technologies and CRC Mining have demonstrated research capabilities in this field • Anticipate that specialist service providers (eg; drilling contractors) will also have significant input into developing industry wide capabilities ACARP Project C15005
