Techno-economic optimization of level and raise spacing in Bushveld Complex platinum reef conventional breast mining. The Bushveld Complex is economically significant and strategically important to South Africa, thus it is imperative that optimal extraction of platinum group metal PGM resources on the Bushveld Complex is achieved. Optimal extraction broadly requires that the maximum amount of ore is extracted by excavating and hauling the minimum amount of waste in the shortest possible time, at the least cost, and in the safest and most environmentally acceptable manner. In open-pit mine planning this entails among other things, minimizing the waste stripping ratio, whereas in underground mine planning it includes minimizing the metres of waste development. In conventional mining, the main development that is in waste or partly in waste and defines the mining grid pattern, includes levels and raises. The techno-economic optimization of level and raise spacing is characteristically a multi-criteria decision analysis MCDA optimization process and should therefore be analysed using MCDA techniques. By using an orebody code named OB1 based on real geological data that was typical of Bushveld Complex platinum reef deposits, the derived optimal range of vertical level spacing was 30 m m, and the optimal range of raise spacing was m m.

It seems that you're in Germany. We have a dedicated site for Germany. Authors: Brady , Barry H. Although Rock Mechanics addresses many of the rock mechanics issues which arise in underground mining engineering, it is not a text exclusively for mining applications. It consists of five categories of topics on the science and practice of rock engineering: basic engineering principles relevant to rock mechanics; mechanical properties of rock and rock masses; design of underground excavations in various rock mass conditions; mining methods and their implementation; and guidelines on rock mechanics practice.

Underground Mining Methods: Engineering Fundamentals and International Case Studies

Despite this fact, ASM is generally associated with the negative aspects of its environ mental impact, and operational research is generally neglected. This article empha sizes the peculiarity of the drilling and blasting systems of small underground mines in selected South American Countries. Such Countries, while having large mineral deposits and well recognized large-scale mining activities, at the same time still pres ent on their territory ASM activities that are archaic, highly inefficient and dangerous for the safety of its operators. This article documents drilling and blasting activities from gold mining in Ecuador and Chile. First, described are the outdated and often non-rational techniques employed by miners, to provide a general framework of the current methods.

The course content will be presented through lectures, case studies, panel. The program includes description and application of underground mining methods,. The Edumine online course Underground Mining Practice. Enroll for Access to All Online Courses. Enrollees have access to all self paced online courses.
