As the near surface deposits are being mined out, underground mines will increasingly operate at greater depths. This will increase the challenges related to transporting materials from deeper levels to the surface. For many years, the ore and waste transportation from most deep underground mines has depended on some or all of the …
Under these circumstances, new, low-cost, and nontraditional methods for deep mining are necessary to develop solutions for these major challenges and thus achieve the safe, efficient, and green exploitation of deep underground metal mineral resources. 2 Major challenges in deep mining 2.1 High in situ stress In situ stress is the …

Before you decide on a specific geographical location for underground carbon storage, it is good to know exactly what you are setting in motion, both with injection, i.e. the process of pumping ...
Underground hydrogen storage has been recognized as a key technology for storing enormous amounts of hydrogen, thus aiding in the industrial-scale application of a hydrogen economy. However, underground hydrogen storage is only poorly understood, which leads to high project risk. This research thus examined the …
The quantification of particulate matter emissions from mineral handling is an important problem for the quantification of global emissions on industrial sites. Mineral particulate matter emissions could adversely impact environmental quality in mining regions, transport regions, and even on a global scale.
Underground coal mining of gas-bearing coal seams is accompanied by the emission of large amounts of methane, which increases with depth. Coal seam methane is not only a major cause of major accidents in coal mines, but is also a greenhouse gas that has a significant negative impact on the Earth's atmosphere. Analysis of the efficiency …
