An Approach to Realizing Process Control for Underground Mining PLOS

This paper presents a new approach to the process control for underground mining operations drilling bolting mucking This approach can estimate the working time and its probability for each operation more efficiently and objectively by improving the existing PERT Program Evaluation and Review Technique and CPM Critical Path Method

Underground Mining Method Example

The slabs obtained in squaring the logs are used underground The legs are 7 ft shoulder to shoulder except on the main level floors in which case they are made 8 ft to give sufficient room for chutes in the main ore ways through the stopes Caps are spaced 5 ft and struts 6 ft centre to centre The detailed dimensions are shown in Fig 6

Estimation of the potential production rate

With this modification it is clear that the Taylor s rule overestimates the underground mining rate since it was calibrated to mostly open pit mines The data used for this calibration included mines using mining methods such as room and pillar cut and fill crater retreat shrinkage slope or sublevel longhole mining methods

Block caving A new mining method arises

Block caving is an underground hard rock mining method that involves undermining an ore body allowing it to progressively collapse under its own weight It is the underground version of open pit mining In block caving a large section of rock is undercut creating an artificial cavern that fills with its own rubble as it collapses

Trends in underground mining for gold and base metals McKinsey

Underground hard rock mining accounts for 40 percent of global mining operations but only 12 percent of run of mine ROM production 1 Underground mines also tend to be more targeted more costly and less productive than open pit mines Because the choice of which underground method to deploy is predominantly driven by the geology of the deposit being mined the operator has little
