Abstract:

Soundless chemical demolition agents (SCDA) are powdery cementitious materials, which upon mixing with water and poured into a confined borehole, generate high pressure causing the destruction of the surrounding material. This poster will present the large-scale test of SCDA performance for rock breakage under biaxial loading conditions, including test setup, biaxial loading frame design, pilot test results, and PFC2D numerical modelling. The large-scale test of SCDA performance is part of a multi-phase project aiming to revolutionize an alternative, explosive-free method for rock breakage in underground mines.

Biography of the presenter: Tuo Chen was born in Shandong, China. He got his master’s degree in mining engineering at McGill University in 2020. Currently, he is a PhD student in the Mine Design & Numerical Modelling Laboratory of McGill led by Prof. Hani Mitri. His research experiences include modelling rock fracture initiation and propagation, dynamically triggered rockburst in underground mines, mining-induced subsidence, etc.
