Here it has been used to model the rock mass response during the planned sequences of excavation-confinement-heating. FRACOD is a two dimensional BEM/DDM code for fracturing analysis in rock material. To quantify the degree of damage during the experiment, an Acoustic Emission (AE) system will be used and strain measurements will be installed. Thermal stresses will be applied in the pillar by the use of electric heaters to reach the spalling conditions. One of the holes will be pressurized with 0.8 MPa water pressure to simulate confinement by backfill. This full-scale experiment is named the Aespoe Pillar Stability Experiment (APSE). Rinne, Mikael Baotang Shen Lee, Hee-SukĪn in-situ experiment has started at Aespoe HRL to investigate the stability of a pillar between two closely located boreholes of deposition hole scale.
