Stope sequencing QueensMineDesignWiki

Stope sequencing. The stope sequencing is one of the most important tools for controlling the behaviour of the rock mass in an orebody undergoing extraction. In order to determine an appropriate extraction sequence, an iterative approach must be taken. Once the prospective location of the pillars is established, the preliminary layout design

Mining sequence optimization and goaf stability analysis

Pumin Iron Ore plans to recovery footwall of No.1 and No.2 stope at610m level,which will influence the stability of whole goafs.To solve this problem,the finite element numerical simulation method is used to simulate 3 kinds of stagewise mining sequence.The separating pillars which withstand main load after mining are taken as objects for research.For the cases of 3 kinds of stagewise mining

11/10/0183;32;This sequence of stages is known as the mining sequence. The mining sequence covers all aspects of mining, including prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials and, once a mine is closed, the restoration of all lands used for mining to their original state.StagesThe mining sequence is divided into six stages.

Mining and Extraction Oxide Ores processes for

Copper is refined from ores in the ground, either through underground or openpit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction Sulfide Ores (1114), but is introduced here because an important byproduct of this process is used for the extraction of oxide ores.
