Shaft mining or shaft sinking is excavating a vertical or nearvertical 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 the top of the excavation is the ground surface, it is referred to as a shaft; when the top ...
Shaft Mining. Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth''s surface. It is found mostly all over the world.
Jan 27, 2014· In mines with shafts, the shaft doubles as a downcast airway a source of fresh air being forced into the mine. Additional shafts are required for upcast ventilation for the remove of stale air; these can also be secondary or emergency escape routes. Other Underground Mining Risks. Old historic mines are often more dangerous than newer ones.

Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies.
Leaky feeder based RF communication system[13] would be established for communication in mine labyrinth gallery in recent future. The carrier current system working on induction theory was used for shaft communication and also experimented in galleries for lineofsight communication working on the same principle.
The Mine Improvement and New Emergency Response Act of 2006 (MINER Act) requires mine operators to adopt underground communications and electronic tracking (CT) systems that meet specific performance goals. The MINER Act was signed into law on June 15, 2006.
The selection of a proper access method is crucial to the overall design of the mine, since it is a long term decision that requires extensive time and capital. The two most common methods of underground mine access to be compared are ramp and shaft access.
Excavation Methods. Vertical Shafts. There are 4 methods in general use: Conventional drill, blast remove stone ("muck out") to surface with a the shaft is to be "lined" ( sides to be covered with a concrete or even a steel lining), this is normally placed as the shaft is excavated.
