1Sensing for advancing mining automation capability:A review of underground automation technology development显示文摘This paper highlights the role of automation technologies for improving the safety, productivity, and environmental sustainability of underground coal mining processes. This is accomplished by reviewing the impact that the introduction of automation technology has made through the longwall shearer automation research program of Longwall Automation Steering Committee(LASC). This result has been achieved through close integration of sensing, processing, and control technologies into the longwall mining process. Key to the success of the automation solution has been the development of new sensing methods to accurately measure the location of longwall equipment and the spatial configuration of coal seam geology. The relevance of system interoperability and open communications standards for facilitating effective automation is also discussed. Importantly, the insights gained through the longwall automation development process are now leading to new technology transfer activity to benefit other underground mining processes.Ralston Jonathon Reid David Hargrave Chad Hainsworth David 2014International Journal of Mining Science and Technology2014,24,3:37

3Longwall automation: Delivering enabling technology to achieve safer and more productive underground mining显示文摘The ongoing need to deliver improved safety, productivity and environmental benefit in coal mining presents an open challenge as well as a powerful incentive to develop new and improved solutions.This paper assesses the critical role that enabling technologies have played in the delivery of remote and automated capability for longwall mining. A brief historical account is given to highlight key technical contributions which have influenced the direction and development of present-day longwall technology. The current state of longwall automation is discussed with particular attention drawn to the technologies that enable automated capability. Outcomes are presented from an independently conducted case study that assessed the impact that CSIRO's LASC longwall automation research has made to the longwall mining industry in Australia. Importantly, this study reveals how uptake of this innovative technology has significantly benefitted coal mine productivity, improved working conditions for personnel and enhanced environmental outcomes. These benefits have been widely adopted with CSIRO automation technology being used in 60 per cent of all Australian underground operations.International deployment of the technology is also emerging. The paper concludes with future challenges and opportunities to highlight the ongoing scope for longwall automation research and development.Ralston Jonathon C. Reid David C. Dunn Mark T.

4Lancet:世界心脏联盟全球心血管疾病预防展望显示文摘动脉粥样硬化性心血管疾病是世界头号致死致残因素,不成比例地影响着中低收入国家(LMIC)的居民。二十世纪六七十年代,心血管疾病被视为高收入国家的常见病,此后通过采取更好的预防措施(如改变生活方式、控制风险因素等),并广泛应用简单有效的紧急事件处理和二级预防措施,心血管疾病的年龄标准化死亡率得以减半。然而,即便在发达国家,所采取的这些行之有效的策略仍远远不够,如果在大多数高收入国家中推广,未来二十年心血管疾病的发生率将进一步降低。Yusuf S Wood D Ralston J Reddy KS 2015疾病监测2015,30,5:14
5Developing selective mining capability for longwall shearers using thermal infrared-based seam tracking显示文摘Longwall mining continues to remain the most efficient method for underground coal recovery. A key aspect in achieving safe and productive longwall mining is to ensure that the shearer is always correctly positioned within the coal seam. At present, this machine positioning task is the role of longwall personnel who must simultaneously monitor the longwall coal face and the shearer's cutting drum position to infer the geological trends of the coal seam. This is a labour intensive task which has negative impacts on the consistency and quality of coal production. As a solution to this problem, this paper presents a sensing method to automatically track geological coal seam features on the longwall face, known as marker bands, using thermal infrared imaging. These non-visible marker bands are geological features that link strongly to the horizontal trends present in layered coal seams. Tracking these line-like features allows the generation of a vertical datum that can be used to maintain the shearer in a position for optimal coal extraction. Details on the theory of thermal infrared imaging are given, as well as practical aspects associated with machine-based implementation underground. The feature detection and tracking tasks are given with real measurements to demonstrate the efficacy of the approach. The outcome is important as it represents a new selective mining capability to help address a long-standing limitation in longwall mining operations.Jonathon C. Ralston Andrew D.
