STOICISM presented in EUROROCK Conference in Salzburg, Austria

    11/10/2015

    As member of STOICISM project, the Exeter University team lead by Dr. Coggan, presented the contribution: ‘Remediation of a hazardous legacy slope face using pre-split blasting’ in the EUROCK2015 conference which took place on 7-10 October in Salzburg (Austria) back to back with the 64th Geomechanics Colloquium, organized by the Austrian Society for Geomechanics. The paper describes the remediation undertaken to alleviate the significant hazard associated with a 26m high legacy slope within an operating china clay pit in SW of England. Remote rock mass characterization of the hazardous slope was undertaken using terrestrial laser scanning from numerous set-up locations to provide geo-spatial data for blast design, kinematic analysis and subsequent instability analyses. The trial pre-split blast resulted in a reduced overall slope angle and sufficient space for design of a suitable rocktrap, thereby reducing the risk to acceptable levels when following a Rockfall Hazard Appraisal System (RHAS). The trial also provided useful guidelines for future use of the technique, particularly for implementation when considering controlled blasting when approaching final pit wall limits.

    The EUROCK2015 conference had 90 oral presentations in eleven sessions (four plenary sessions, seven parallel sessions), while about 100 papers were presented as posters during the event. More than 1000 participants attended the event majority (78%) from the German speaking countries, but attendees from Canada, India, Iran, Australia, USA also attended where 16% were students and 11% women.  The topics addressed in the event were rock and soil stability due to tunnelling, mining excavation activities, civil underground construction structures as well as monitoring and safety management measures.
