Abstract:
Significant contributions have been made to the development of new numerical monitoring and modeling techniques and predictions of land and building deformations located above the underground gaps, including the implementation of a telemetry monitoring system, the pioneering use of a Global Satellite Positioning System, a numerical method of deterministic modeling of land deformations and constructions located above the underground voids in crushed rocks and salt rocks, and the use of hydrographic elevations in offshore monitoring. Their applications are discussed in case studies of land deformation and construction deformations located above the underground voids in the Jiu Valley coal mines. It should be noted that Canada was one of the countries where monitoring was constantly evolving, with the evolution of activity in this area being significant for the whole history of the field.
