| 總結: | Instability in underground mining can arise from large opening dimensions,
impacting not only safety but also economic aspects. Stability studies of mining
openings are conducted by companies to maximize the dimensions of mining
operations. This study applies numerical methods to analyse the mine opening in
underground cut and fill gold mine. A total of four mining scenarios are formed to
illustrate mining sequences and a support analysis is conducted to obtain the
stability of the mine opening. Total displacement, yielded elements, and support
capacity plot are used as stability indicators in each scenario. Through the
interpretation of the total displacement, the deformation reduction is obtained in
each mining scenario. Meanwhile, through the yielded element it can be seen that
the majority of opening scenarios experience a reduction in collapse height in each
scenario except for the 3rd scenario where there is additional collapse on the left
wall. Then, by analysing the support capacity plot it is proven that each scenario is
in a stable state with the recommended types of reinforcement and rock bolt,
shotcrete, wire mesh, steel set, and wooden supports according to the characteristics
of each scenario. |
