The "glory-hole method" in mining refers to an excavation process where soft or broken ore is drawn off through an underground passage. This method is particularly useful when simplifying the construction of large shafts. In this technique, the main shaft is initially sunk by blasting. The resulting broken material, or muck, is then dumped into a central "glory hole" that has been previously.. Glory hole mining is a method of ore extraction that utilizes gravity to transport broken rock from a pit to underground haulage levels, making it suitable for deep ore bodies that are too costly for traditional methods. This technique is characterized by specific conditions such as steeply dipping ore bodies, large-scale deposits, and a high recovery ratio, while also requiring careful.
A "glory hole" is a term used in the mining industry to describe several different types of excavations that commonly occur during the process of creating an open pit, drilling a mine shaft, or using the block caving method of creating and managing a mine. Most methods of underground mining are likely to produce some sort of glory hole, although this type of open excavation can also be part of.. Definition of glory-hole system A method of mining using a system of haulageways beneath the block of ore, which has had its top surface exposed by the removal of the overburden. Over the haulageways are chutes that extend up to the surface, and are spaced at intervals of 50 ft (15.2 m) or at any other convenient distance.
