Numerical methods for the design of support systems in a deep metalliferous mine in Turkey

Selection of support system is important for safety concerns and economic aspects. The purpose of this study is to investigate the design of support system specific to an underground mine in Balya, Balikesir, Turkey. The mine has been operated by Eczacibasi Group Esan Company since 2009 for lead and zinc production. Support systems were designed by using rock mass classification systems based on the data regarding underground openings, rock mass and support materials. The suitability of the designs were evaluated by using numerical methods to understand the effect of support materials by considering the difference between total displacement and strength factor both for supported and unsupported conditions. The effect of existing underground openings that are adjacent galleries were also simulated in the numerical models that could not be modelled in rock mass classification systems. The studies were completed a design procedure for a similar underground mines successfully.
