AbstractThe Canadian Mine Technology Laboratory (CMTL) can be broadly divided into four main sections; Numerical Modelling, Instrumentation Development, Rock Properties and Support Systems and Mine Methods and Equipment. The major thrust in numerical modelling at CMTL is to adapt codes written for main frame computers to the personal computer environment. Several 2-D models including PCSAP2D, PCEPFE and PCMINTAB as well as a 3-D Boundary Element Application Package have already been developed. Instrumentation is developed for both project specific reasons and as more generally applicable research tools. The latter includes CANMET's new strain monitoring system and fiber-optics camera as well as recent advancements in tomographic sensors and analysis. Recent rockburst activity has led to the development of the Sudbury Local Telemetered Network for the Sudbury basin to monitor natural and mine-induced seismic activity. In addition macroseismic networks have been installed in area mines for source location of rockburst activity. A new backfill laboratory has been set up on the Laurentian University campus to study the physical and engineering properties of backfill materials and costs associated with their use underground. It will also supervise the seven MDA research projects currently underway. The Rock Properties and Support Systems (RPSS) group has recently acquired an MTS 880 Rock Mechanics Test System, a computer-controlled, servohydraulic, stiff test frame. This provides a facility for advanced testing not possible with conventional equipment. In addition, the CANMET's Elliot Lake Laboratory operates the largest test frame in Canada with a axial load capacity of 18,000 kN. Projects planned for the '89/'90 fiscal year include work on the underground burial of high level nuclear waste, surface crown pillars, small mine stability, evaporite mining and the development of data bases for technical advances in rock mechanics and mechanical rock properties. The Mine Methods and Equipment group keeps abreast of developments in the mining industry throughout the world and disseminates the information through seminars, annual reviews and state-of-the-art papers. It also seeks to promote cooperation in the industry by maintaining a national information bank on current and developing mining technology and prevalent mine operational problems.
