Stoping is the process of extracting the desired ore or other mineral from an underground mine, leaving behind an open space known as a stope. [1] Stoping is used when the country rock is sufficiently strong not to collapse into the stope, although in most cases artificial support is also provided.
Explore the essentials of stope mining, from techniques and methods to considerations for creating productive stopes in underground mines.
13. Dez. 2022 · Unlike surface mining, stope mining can have a more successful stripping ratio and mine high grade ore at a lower cost. This guide outlines the important purpose a stope serves in underground mining and the methods for creating and utilizing them.
16. Jan. 2022 · The stability graph method for open stope design is one of the most widely used approaches for predicting the stability of stopes in underground metalliferous mines. The primary purpose of this work is to propose a new stability chart, which includes all relevant case histories, and to exclude parameters with uncertainties for ...
A review of the factors controlling stope wall behaviour such as excavation geometry, rockmass strength, induced stress, ground support, blast damage and drill drive layout is undertaken. In addition, the advantages and disadvantages of single lift stope geometries linked to vertical crater retreat are also analysed.
