Paper Number: ISRM-EUROCK-2020-044
... 1959, the deposit was produced by open-pit mining. At present the deposit is being developed by the Severny underground mine. The principal mining method is sublevel caving and in some parts, the open stoping mining method is applied. As a result of recent in-situ studies, the stress field has been...

... Abstract A first attempt of using the Room and Pillar mining method in the Czech Republic was implemented in the southern part of the Upper Silesian Coal Basin. This stratigraphical unit is well known for its complex geological structure with more than 40 main coal seams vertically distributed...

... stoping, and is now changing to sublevel caving. To change mining methods the crown pillar left to support the sublevel stopes will be removed before the sublevel caving can begin. In the western part of the mine the crown pillar has been removed, resulting in caving of the hangingwall. The underground...

... efficiency till the last moment before the collapse. The analysis of cause of this collapse shows that the main reasons of the collapse are rejection of low levels stowing; disparity of design principles to rock mechanics features of the Annenskiy Mine. Shown limitation of the room and pillar mining methods...

... underground mines in order to help planning the mining method and necessary supports. This paper presents the analysis performed for two gold mines in hard jointed rock masses. In one of them, the geological complexity of the ore and the presence of a graphitic schist in the hanging wall induced the use of...
