GEOTECHNICAL APPLICATIONS IN OPENCAST AND UNDERGROUND MINING WITH CASE STUDIES
Date : 25th-26th February, 2022.
The webinar will address practical training and continuous effort in developing Professional Competence and Excellence' among Geology, Geotechnical and mining professionals.
Nowadays, most of the stability of opencast and underground excavation design and construction are based on the sound principles and good understanding of best practices of Rock engineering, whether it may be pit slope stability, underground stope design, excavation sequencing, or design of waste dumps or tailings impoundment structures for the storage of tailings from Mineral processing plants.
Ensuring Safety and Stability of the excavation is of primary concern to the planners, operators and the mine managements. During the project stage, or operational stage , proper planning and design of surface or underground excavations can be achieved based on geo-technical/ rock mechanics investigations for ascertaining the envisaged strata conditions to avoid unexpected consequences and costly mistakes, which may lead to loss of production and safety concerns.
The 2-day on-line training program will address day to day stability problems in operating mines and to how to minimize the risks associated with long-term stability and safety for enhancing productivity followed by case histories around the world.
The case studies include slope stability analysis of selected Iron ore, chromite and other mines, Design of underground excavations, support methods, stoping methods, pillar design and phasing of extraction, from lead-zinc, copper, chromite and coal mines. In addition, design of waste dumps, stability aspects of waste dumps and tailings dam design and construction for ensuring the long-term stability will be discussed. Design of transportation tunnels for installing conveyors, railway tunnels including monitoring the stability of structures with different types of on-site geo-technical instrumentation. Different types of geotechnical instrumentation, choice of selection, site selection, planning, installation and interpretation data for predicting strata conditions.
WHO CAN PARTICIPATE:
The training program has been tailored in such a way to handle the day to day practical problems faced by the mining engineers, geologists, civil engineers, mine management, Government departments, state and central government departments, universities, mine safety and other related disciplines.
