Check sensitivity-factors and complete preliminary Overburden Slusher stripping alternatives. The option over the Glendell property was exercised following this study.
● Allied Queensland Coalfields. Complete preliminary mine plans for coal supply tender to QEC considering three levels of production using; truck-shovel, dragline, and dragline with truck-shovel prestrip. Innovative mining systems were found to be more attractive from an operating cost view point and included; Co-Axial Pipe conveyor with Shoveller loader, and two sizes of custom-built Overburden Slushers.
● BHP Research - Melbourne Laboratories A 1:40 scale model of the BOSMIN Overburden Slusher system of stripping was operated to test various stripping sequences and to develop alternative hoe design concepts. The load by load model operation for a 60 m deep pit exactly matched the computer simulation for the same task.
● Peak Downs Mine Overburden Slusher Stage 1 Field Trials. BHP-Utah Coal Limited are the operators of this large open cut coal mine and have supported the investigation of the BOSMIN Overburden Slusher method of stripping over several years. This series of trials were internally funded, and involved the operation of a 57t hoe over a three-week period to demonstrate the longer term OS stripping sequences. The trials concluded that the hoe was controllable over an extended pulling distance, and that Slusher stripping was practical.
● South Blackwater Mines Review. QCT Resources Limited. The study involved the detailed assessment of this large coal property including both open cut and underground development, which was on a sale offer. The client made a successful bid and is now the owner/operator of the mines.
● Overburden Slusher (OS) Study. # 1217 NERDDC Project. R. Beatty was the NERDDC appointed project supervisor for this study. The study was commissioned to progress the OS method of stripping, which is a patented mining process registered under the BOSMIN trade mark. The OS stripping system involves attaching a large hoe between two winches situated at the tops of the open cut high wall and low wall. Operating the large hoe between the two winch units showed significant energy savings relative to all the alternative dragline based stripping methods. The OS process also demonstrated that; no spoil pile levelling was required, a completely stable low wall due to the lower bank angle was possible with the OS, it was feasible to convert existing dragline and shovel equipment for OS use, and it would be possible to eliminate low wall ramps.
● Gloucester Coal Project - ESSO Australia Limited. Stage one review of the available mining options for this small, multi seam coal deposit. The study resulted in an extension study centring on the innovative Co-Axial Pipe (CAP) conveyor concept, developed by Mr. Beatty under the BOSMIN trade mark. The CAP option appeared to be the most cost effective method for mining this structurally disturbed deposit.
● Dragline Hopper Crusher Conveyor Study - # 86/1022 NERDDC Funded Project. R. Beatty was appointed Project Manager on behalf of CSR Limited - the designated representative to the NERDDC funding committee, MIM Holdings, and BHP-Utah Coal Limited. The study reviewed the previous art and contemplated mechanical, mining and earth-science aspects of this new stripping method. Study isolated the pertinent design factors associated with dumping dragline spoil into hopper/crusher/conveyor (DHCC) systems, as well as the hopper/truck (DHT) alternative. The study resulted in a comparative cost analysis for dragline only stripping, dragline with bucket wheel excavator pre strip, dragline with truck-shovel prestrip, DHCC and DHT. A further series of trials was recommended to further the DHT concept as this appeared to be the most cost competitive method of deep stripping studied.
● Coal Mine Review - Confidential. The study involved an opportunity review of a large coal mining complex for a multi-national client wishing to invest in the Australian coal industry.
● Coal Mining Cost Study - Multi client response. The study used broad brush publicly available and in-house non confidential library information, to develop a costing model which ranked Australian coal mines and compiled specific mine geological and plant data.
● OS Study - Riverside Mine, Thiess Dampier Mitsui. The overburden slusher post stripping study considered the application of OS techniques to the task of relieving spoil pile failure impacts on coal production. The study showed the point beyond which it would be cheaper to convert a dragline for slushing duty.
● Hail Creek Mine Plan. Conducted on the behalf of CSR Limited's joint venture. A complete review of all the possible open cut mining techniques available to this deposit including the BOSMIN proposals for overburden slushing and truck jigging. The review was required as a 'first-principles' approach to this long studied deposit, and the results favoured the BOSMIN mining systems.
● Charbon Colliery Mine Plan. Conducted on behalf of Blue Circle Southern Cement Collieries Pty Ltd. A complete review of all potential open cut coal surrounding the Charbon Inlier was conducted. The reserves identified were detailed in preference order and a subsequent detailed design was used as a basis for preliminary extraction.
