The world is presently facing many challenges relevant to mining such as an increasing demand on various minerals, a higher requirement for energy, and a rising CO2 release.
Mining supplies various raw materials with an increasing annual production. Because minerals resources are non-renewable, various minerals in the earth will be depleted sooner or later. At the same time, unfortunately, a vast amount of minerals is lost during mining operations.
In addition, mining production requires energy in different forms, but the energy efficiencies in mining operations are very low. To reduce ore loss and to increase energy efficiency are two great and challenging tasks for future mining.
Mining depth becomes greater, resulting in higher in-situ stresses. Consequently, the higher in-situ stresses lead to many problems (such as rock bursts, rock fall or collapse, and seismic events) and difficulties in rock drilling, rock blasting, and rock support. Most of such problems or difficulties are involved rock dynamics.
Rock mass is natural solid containing various geo-structures such as joints and faults, making both rock mass evaluation and mining in great depth difficult. Accordingly, new methods such as muography for deep mining and rock mass evaluation are necessary.
For a long term, it may be necessary to consider space mining.
Based on the above aspects, this Summit invited many experts, including several world’s top leading scientists and R&D leaders over the world. The topics of invited speeches cover most fields in mining, as follows:
- Minerals losses and energy utilization in mining industry
- New mining methods and technology
- Rock dynamics and deep mining
- Rock support
- Rock blasting and fragmentation
- Rock mass evaluation
- Case studies in mines
- Muography, space mining and mining education
