Application of UBC methodology for underground mining method selection

Abstract

The total operating costs of each mine largely depend on the method of mining. Therefore, the appropriate choice of the method of mining excavation is very important and great attention is paid to this issue. There are several procedures for the selection of the mining method, among which the most important and most commonly used numerical method is the UBC methodology for the selection of the mining method. According to this methodology, the choice of the method of mining excavation is based on the mining-geological parameters of the ore and adjacent rocks. In this paper, the UBC methodology for the selection of the mining excavation method for a specific case will be applied. According to this methodology, it was obtained that Cut and Fill method is best ranked for specific conditions and the most appropriate way of mining.

Underground Mining Method Selection According to Nicholas Methodology

“…The comparison of the relative cost of excavation for individual excavation methods, is based on the fact that each of the excavation methods is applied in conditions that suit it. For this purpose, it is necessary to take into account the mining-technical and economic factors, i.e., to make the optimal choice of the method of mining excavation [2].…”

“…This paper examines the active underground mine of lead and zinc, where a new part is opened and it is necessary to choose the appropriate method of excavation [2,3,8]. The input data for the ore deposit are given below.…”

“…-mining-technical factors, such as: annual productivity, applied equipment, health and safety, environmental impact, ore dilution, mine recovery, flexibility of methods, machinery and mining rate, and economic factors, such as: capital cost, operating cost, mineable ore tons, orebody grades and ore value. The process of choosing a method of mining excavation can be divided into rational and optimal choice of method of mining excavation [2].…”

Environmental geotechnology for low-grade ore mining with the creation of conditions for the concurrent disposal of mining waste

“…Восходящий порядок отработки рудного тела, шахматное расположение камер по высоте и оставление изолирующих треугольных целиков позволяют изолировать отрабатываемую камеру от соседнего выработанного пространства, заложенного отходами, тем самым формируя емкость для возведения бесцементного закладочного массива, а усеченная форма неизвлекаемых целиков обеспечивает минимизацию их размеров. Показатели традиционной системы определены при рациональном соотношении ширины и высоты панели -15×20 м, 20×25 и 25×30 м [31] по общепринятой методике [32]. При предлагаемой технологии потери руды в изолирующих целиках усеченной формы составляют основную долю от суммарных эксплуатационных потерь при выемке запасов.…”

Underground Mining Method Selection with the Application of TOPSIS Method

“…There are orientation parameters for these mining methods, which have been confirmed in the available practice. These mining methods were also obtained as the best ranked mining methods according to rational choice, i.e., according to the UBC methodology [20]. These mining methods will be alternatives for the optimal choice of the mining method (see Table 2).…”
