SUMMARY:ATS QLD - Discrete fracture network approach for underground support design optimisation
DESCRIPTION:Ground support design for underground rock engineering projects often adopts empirical methods\, which were mostly developed in 1960s and 1970s. While these methods have provided a useful tool to aid design\, they have typically been based on a limited database of project experience and so their results need to be interpreted in the context of local experience and engineering judgement. Discrete Fracture Network (DFN) model allows inclusion of site-specific discontinuities data to be stochastically quantified and explicitly adopted as design input. Combined with 3D Distinct Element Method\, this approach offers a more quantifiable\, verifiable and reproduceable method to assess rock mass quality & behaviour in underground excavation projects. \nThis presentation demonstrates benefits gained from this integrated approach in ground support design for large span rock caverns using a case study. The use of DFN and explicit modelling has allowed ground support to be optimised based on site-specific and more realistic anticipated ground conditions. Ivan is the David Sugden Award winner for 2022 and will present his award-winning paper in person entitled: Discrete Fracture Network Approach in Ground Support Design Optimisation for Large Span Cavern in Jointed Rock Mass. The David Sugden Award was initiated by the ATS in 2004 to encourage young engineers to develop the art of technical writing. The competition is open to all ATS members and university students under 35 years of age. \nLearning Outcomes\nIvan is the David Sugden Award winner for 2022. He will present his award-winning paper in person. This presentation\, so-called’ David Sugden Award Road Show’ is one of the annual events organised by ATS. Key takeaways will include: \n\ninterpretation of discontinuities in rock mass using DFN application of the advanced analytical method to understand rock mass behaviour\nactual large cavern design case.\n\nEvent Program\n\n5.30pm: Welcome and light refreshments\n6.00pm: Presentation commencement\n7.00pm: Networking and drinks\n7.30pm: Event concludes\n\nTicket Inclusions\n\nLight refreshments\nCanapes\nNon-alcoholic beverages\nAlcoholic beverages\n\nAbout the speaker\n \nIvan Haryono\, MIEAust CPEng NER\nSenior Associate Geotechnical Engineer\, WSP \nIvan Haryono is Chartered and Registered Professional Geotechnical Engineer with over 12 years of experience on large scale tunnelling and deep excavation projects in Hong Kong\, Canada\, Australia\, Singapore\, and the Netherlands in different project stages; from tender & detailed design\, construction phase services\, forensic analysis and claims\, and independent review. He has worked on various Drill & Blast tunnels\, TBM tunnels\, deep shafts in both soft ground and rocks; for metro railway & stations\, highways\, wastewater treatment plants\, and mines. He is experienced in advanced numerical analysis for soil or rock mechanics and ground-structure interaction problems\, including finite element\, finite difference\, & distinct element methods\, and discrete fracture network modelling.

SUMMARY:Mt Coot-tha Quarry Site Visit - Register Now!
DESCRIPTION:REGISTER NOW – Limited Places \nFollowing the success of the Mt Coot-tha Quarry site visit in 2020\, ATS Queensland is again excited to invite members to Quarry Day 2023 on 31 August 2023 proudly supported and sponsored by our prime sponsor DESOI. \nThe day is aimed at graduate and early career professionals and will cover a range of equipment and technical demonstrations. These will feature: \nRock fissure and crack injection – DESOI \nShotcrete pumping and application – JEMNA \nLithium battery exposed to high temperature – STACEY AGNEW \nUse of drones in a construction setting – UNIVERSITY OF QUEENSLAND \nRock drilling – OPTIONX \nRock drilling – VERMEER \nMASTER BUILDERS SOLUTIONS + BLUEY TECHNOLOGIES ANZ \nProducts – BluCem HS200 RMX\, BluCem HS200\, MasterSeal 345 \nBluCem HS200 RMX\, is a ready mix product which arrives pre-mixed in concrete agitators on site to form an ultra-flow cementitious grout. BluCem RMX HS200 is a pumpable\, high strength product suitable for civil engineering applications. BluCem RMX HS200 incorporates advanced additives to form a cementitious grout which is free of alluminate and metallic expansion agents or methocel based additives providing a product suitable for 100 year design life applications. \nBluCem HS200\, is a one component powder product which requires only the addition of water to form an ultra flow cementitious grout. BluCem HS200 is a pumpable\, high strength product suitable for civil engineering applications. BluCem HS200 incorporates advanced additives to form a cementitious grout which is free of alluminate and metallic expansion agents or methocel based additives providing a product suitable for 100 year design life applications. \nA coffee van in the morning available in the quarry (kindly supported by the exhibitors). \nNote: All delegates will be required to wear long pants\, closed toe safety boots and a long sleeve shirt. Reasonable fitness and mobility is required as the tour involves walking through a working quarry. \n  \nSchedule \nThe day will be split into two parts: \nSession 1 – Commence 0800 Induction. \nIn the quarry with a chance to meet the supplier and see hands on demonstrations; \nLunch – Mt Coo-tha Cafe; and \nSession 2 – Presentations from the demonstrators and suppliers covering the morning’s activities with the opportunity for Q&A. \nFinish 1530 \nNote that demonstrations and presentations are subject to change on the day. \n\n Prime Sponsor \n \nIS YOUR PARTNER FOR INJECTION TECHNOLOGY
