The stability graph was introduced approximately three decades ago for open stope design.
Since then, it has gained wide recognition in open stope design around the world in hard …

The Mathews method of predicting open-stope stability was first proposed in 1980. The
initial stability graph was based on a limited number of case studies, primarily from deep …

The assessment of the stope stability is of great importance in the underground mine design
process. The instability of stopes leads to serious economic and safety problems in mining …

Unplanned dilution and ore-loss are the most critical challenges in underground stoping
operations. These problems are the main cause behind a mine closure and directly …

The stability graph was introduced in 1981 by Mathews and co-workers in Golder
Associates. This period coincided with the shift from open pit mining to underground bulk or …

This thesis presents the results of open stope stability and dilution research which focused
on evaluating and quantifying stress, undercutting, blasting and exposure time and their …

This thesis presents new methods to improve open stope hangingwall (HW) design based
on knowledge gained from site visits, observations, and data collection at underground …

Ore dilution is a fundamental problem for the production process in underground mining
operations. Especially in open stoping methods of underground mining, the continuous …

Unplanned ore dilution or stope overbreak, which has a direct and large influence on the
cost of a stope, and ultimately on the profitability of a mining operation, can be attributed to …

The stability graph method for open stope design is an empirical method, and its
interpretation is highly subjective. Subjective interpretation of the stability graph has resulted …
