Groundbreaking news! McGill University research team of Professor Hani Mitri – Director of McGill’s Mine Design Laboratory, has recently completed the first underground mine trial to break hard rock without explosives. Situated more than 500 m below surface, the trial site is an excavation intersection that was to be slightly widened (slashed) to facilitate mobile equipment traffic. The McGill team used the so-called soundless chemical demolition agent SCDA to perform the trial. SCDA is a powdery cementitious material that when mixed with water and injected in a borehole, it will expand and exert pressure on the borehole The McGill team designed a novel borehole pattern along with a new method to inject the holes using 3D Printing technology. The trial slash fractured after 17 hours, and the broken rock was easily removed with a scale bar. This is the first of a series of trials to be conducted in 2022.

Welcome to our website. Designed by my research group, this site aims to provide you with a quick yet complete overview of the research and industrial activities that are happening in the Mine Design & Numerical Modelling Laboratory.

Founded in 1988, the Lab is dedicated to provide quality training to students, researchers and practitioners. Thanks to the generous support of our sponsors, the Lab is equipped with state-of-the-art mine design tools. The diversity and expertise of the people involved has boosted our ability to tackle challenging projects and to provide quality service to industry.
