The session will open with a presentation from Mike Calderone, manager, controls and automation systems, JoyGlobal, and Scott Langley, COO, White Oak Resources, titled Partnering to Develop a Productive Automated Longwall System. They will review the partnering that took place between a longwall operator and a supplier to develop a world-class longwall system incorporating the benefits of the latest automation technologies. In his presentation, Application of Shearer Automation in Australia, Stephen Douglas, project manager with automation responsibilities, Eickhoff, will share experiences encountered from an OEM perspective on the journey to apply automation. Douglas believes it's the small ideas and the intermediate steps that will take longwall automation to the next level, and an inside view could result in more action globally. Zbigniew Stopa, vice president, Lubelski Wegiel Bogdanka S.A., will present Longwall Extraction of Thin Seams at Poland's Bogdanka Mine Using VFD Technology. In 2012, Bogdanka started a second plow face, but this time based upon variable frequency drives (VFDs). He will provide an overview of the VFD technology and compare operational experiences between conventional and VFD-powered systems. Reinhard Neuper with Kopex Machinery will present Automated Longwall Systems: The Pniówek Experience. He will cover the control system options of electrical equipment, AFCs, powered roof supports with electrohydraulic control system and SCADA. The KSW-460NE1 shearer offers web mapping as an internal function of the control system for the shearers and the capability of direct control from the overriding control system. May 2013 Application of Shearer Automation in Australia By Stephen Douglas, project manager with automation responsibilities, Eickhoff Australia pty Ltd. Longwall Extraction of Thin Seams at Poland's Bogdanka Mine Using VFD Technology By Zbigniew Stopa, president of the management board, Lubelski Wegiel Bogdanka S.A.; and Dr. Michael Myszkowski, product manager AFC/Plow, Caterpillar Global Mining Europe GmbH Automated Longwall Systems: The Pniówek Experience By Reinhard Neuper, vice president for product development, Kopex Machinery S.A Session 5: Reliability & Maintenance (Thursday, June 13, 2013, 9 a.m.-11 a.m.) Asset Reliability at the San Juan Mine By Michael J. Fidel, manager maintenance, San Juan Coal Co. Challenges for Successful Ground Fault Protection of VFDs Used in Underground Coal Mining By Bobby Houston, eastern division general manager, Intermountain Electronics Inc., Pat Lemmon, project manager, Intermountain Electronics Inc., and James K. Martin, vice president, Intermountain Electronics Inc. Smart Services in Support of Benchmark Longwall Production By Dieter Haage, head of underground excellence, Anglo American Coal Australia pty Ltd. Faster Roadway Development: Slow Cutting for Higher Productivity and Safety By Kirby Owen, product support manger mechanical cutting, Sandvik Mining and Thomas Vallant, manager sales support mechanical cutting, Sandvik Mining Impact of Corrosion on Mining Equipment By J.V. Pellegrino Jr., senior materials consultant, RJ Lee Group, USA Reliability & Performance The final session takes place Thursday, June 13, at 9 a.m. The session kicks off with Michael J. Fidel, manager maintenance, San Juan Coal Co., presenting Asset Reliability at the San Juan Mine. High asset reliability is paramount to any capital intensive business. Successful reliability programs limit risk, increase runtime and reduce cost. Reliability initiatives are not maintenance centric, but a collaborative effort from all line functions within the business. In his presentation, Challenges for Successful Ground Fault Protection of VFDs Used in Underground Coal Mining, Bobby Houston, Intermountain Electronics will discuss the issues longwall operators have to consider when installing VFDs in underground coal mining applications. One issue for consideration involves the performance of ground fault protection devices when applied with a VFD operating at various speeds (See Underground Safety Equipment, p. 44). Haage will return again to present: Smart Services in Support of Benchmark Longwall Production. Anglo American is currently engaged in a smart service partnership with JoyGlobal related to longwall operations at Moranbah North. This presentation is intended to show how the partnership with JoyGlobal has performed and what benefits Anglo American has realized. Kirby Owen and Thomas Vallant, Sanvik Mining will present Faster Roadway Development: Slow Cutting for Higher Productivity and Safety. They will discuss the development productivity improvements achieved by the MB610. Its unique slow cutting speed provides high cutting forces, resulting in an increased cutting rate and reduced dust creation. Crews at CONSOL Energy's Bailey mine have advanced a total of 17,700 m (58,000 ft), with an average shift advance of 36.7 m (120 ft) during 2012. The technical program concludes with Impact of Corrosion on Mining Equipment by J.V. Pellegrino Jr., RJ Lee Group, USA. He demonstrates the impact of corrosion on various longwall components. ww.coalage.com 25
