N2 - The utilization of sublevel stoping as a mining method has experienced a big upswing in recent decades. The reasons for this are manifold ranging from economic to rock mechanical aspects. The questions this thesis addresses are: “What are distinctive characteristics concerning the current field of application” and “Which differences / trends regarding the implementation of this method can be identified?” These questions are specifically related to European and Canadian mining operations. In order to answer these questions, 8 to 12 sublevel stoping operations were researched in various topics. Furthermore, several related studies were used to obtain additional reference data. Using this established dataset, geometrical and rock mechanical parameters related to the deposit as well as design parameters related to the implementation, could be analyzed and compared with each other. Based on this process of analyzation, various differences could be highlighted and possible trends concerning the utilization of this method, identified. A further aim of this thesis is to provide a detailed State-of-the-Art overview, concerning all major elements of a sublevel stoping operation. The relevant questions in that context are: “Which design methods are in accordance with today's State-of-the-Art and can be applied to the individual elements?” and “What are the key aspects / parameters influencing the design process of these subparts?” The answers regarding both questions are partly based on literature research and to a certain extent on real-world data / cases.
