Shaft Mining Encyclopedia MDPI
Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects differ greatly in execution method from deep shafts, typically sunk for mining projects. When the top of the excavation is the ground surface, it is referred to as Vertical shafts play an important role in the safe operation of mines. The stability of vertical shafts has always been a difficult problem in mining engineering, especially with the increasing of mining depth. In order to keep the engineering works stable, it is necessary to make the deformation failure mechanism of vertical shafts Deformation Failure Mechanism of Deep Vertical Shaft in Jinchuan Mining

Effective Visible Light Communication System for Underground Mining
In general, underground mines consist of mining roadway and mine working face. Most of the previous works considered the horseshoe shape for mining roadway and a rectangle chamber for working face [9]. • Mining roadway: Mining roadway is a universal term used for shafts, tunnels, and chambers. It isAfter summarizing and evaluating works on system reliability, various models and results for predicting and evaluating system reliability have been introduced.

Engineering Manufacturing Shaft Conveyances Mining
The hazards associated with shaft haulage has led Australian Standards to set out specific requirements for designing, constructing, and inspecting conveyances in vertical shafts in AS/NZS 3785.4 Underground mining Shaft equipment Conveyances for vertical shafts. These standards aim to guarantee the safety and health of mine workers.2.1 Mining and Milling. Uranium is excavated from open-pit or deep-shaft mines using conventional mining techniques (step 1 in the fuel cycle). The ore is crushed and the uranium is leached out using sulfuric acid or sodium carbonate and bicarbonate.
