Mr. Hughes has extensive experience working at ICL on developing enhancements to the InSite application including a new 3D visualizer, tools for velocity model calibration, array analysis, discrete fracture network inversion, source scan location and the real-time triggering of data from miniSEED files and multiple arrays.
He has also revised and enhanced the data acquisition software used with ICL’s laboratory test equipment. His expertise is in the use of the C++ programming language using Visual Studio. In addition to this, he has extensive experience using MFC, OpenGL, HDF5, SQL Server, .NET and TCP/IP socket programming.
In total, he has over 30 years of experience developing software, mainly PC based, but also hosted on embedded and IP telephony platforms. Mr. Hughes holds a B.A. in Physics from Oxford University.
The Fifth International Itasca Symposium will be held at the University of Vienna (Austria). The Symposium will features the application of Itasca software for solving engineering and scientific challenges in geomechanics, hydrogeology, microseismicity, and more.
Mr. Flynn is an applied physicist with a diverse technical background with over 20 years of experience in instrumentation and measurement systems, with a focus on acoustic emission and ultrasonic monitoring for the past 8 years.
He is the General Manager of the ICL office and also the product manager for ICL’s range of hardware products.
Caving is applied to increasingly deep, large, strong, and heterogeneous ore bodies. This increases the risk of stranded reserves in overhangs, potential for cave stall and air-blast, infrastructure rehabilitation or loss, and large-scale caving-induced subsidence. Geomechanical analyses are therefore critical to understand and predict:
Itasca simulates mine caveability and subsidence using the continuum program FLAC3D and the discrete element programs 3DEC and PFC to predict the progressive failure and fragmentation of the rock mass from an intact/jointed to a caved material. Both FLAC3D and 3DEC can utilize Itasca’s CaveHoek and Imass material models, whereas both 3DEC and PFC can utilize bonded or free-flowing blocks/particles.
Coupled with Itasca’s deterministic, physics-based code REBOP or the statistical, cellular automata code CAVESIM, the collapse, bulking, and movement of caved rock can be better incorporated. The coupled method captures many important aspects of caveability affecting cave design, such as hang-up formation, material recovery, timing of surface breakthrough or interaction with other lifts, crater development, and surface subsidence.
