To study the possibility of utilizing mixed construction waste and ultrafine tailings (CW&UT) as a backfilling aggregate that can be placed underground in a mine, physicochemical evaluation, proportioning strength tests, and pumpability experiments were conducted. It was revealed that mixed CW&UT can be used as a backfilling aggregate due to the complementarities of their physicochemical proper...

Robots’ visual perception is a field that is gaining increasing attention from researchers. This is partly due to emerging trends in the commercial availability of 3D scanning systems or devices that produce a high information accuracy level for a variety of applications. In the history of mining, the mortality rate of mine workers has been alarming and robots exhibit a great deal of potentials...

We developed an efficient algorithm that generates optimal stope layout for underground mine. After a mining site has been identified and exploration done, the data gathered is analysed modelling technique applied to produce ore body. The body divided into thousands of blocks in three dimensions. are assigned values per tonne. miners desire which maximizes mine value. In this paper, we present ...

The Stope Boundary Optimization (SBO) problem refers to the layout design of production areas (stopes) in an underground mining operation. It falls within domain strategic mine planning and a model that addresses this aims maximize profitability, offers optimal management mineral resources facilitates decision making around capital investments. SBO is computationally complex method solution rea...

Cemented paste backfill structures are complex underground cementitious structures. After fresh cemented paste backfill (CPB; a mix of tailings, binder and water) is poured into underground stopes (mined-out voids), its strength which is a key mechanical design criterion of CPB structures, gradually develops with time. The development of CPB strength is governed by the coupled thermo-hydro-mech...

Minimizing dilution is essential in open stope mine design as excessive unplanned can compromise the operation's profitability. One of main challenges associated with empirical graph method used to stopes how determine boundary zones objectively. Hence, this paper explores implementation machine learning classifiers bridge gap conventional method. Stope performance data consisting (unplanned di...

Underground stope stability has important implications for the safety and efficiency of metal mining, especially when there are subsidence zones above. To analyze around area Hongling ore body, this paper innovatively adopts 3Dmine–Rhino3D–FLAC3D coupled modeling numerical method to model predict excavation process area; it monitors analyzes displacement stress-distribution changes in a selecte...

Production planning in mineral exploitation should be undertaken to maximize exploited ore at a minimum unplanned dilution. Unplanned dilution reduction is among the ways to enhance the quality of products, and hence, reduce the associated costs, resulting in a higher profit. In this way, firstly, all the parameters contributing to unplanned dilution in underground stopes and specifically the c...
