... ABSTRACT: Mining at depth in a South African gold mine, poses common risks and hazards. Many seismic events have, in the past and present, resulted in the loss of life of several employees. Most of these were inexplicable, and no consideration was given in any study where the orebody being...

... ABSTRACT: As mines are getting deeper, mining induced seismicity becomes a major hazard threatening the health, safety, and security of operations. In today's mines, seismicity is well measured and documented. However, the ability to foresee events lags behind. This paper will discuss...

... ABSTRACT: Chuquicamata, located in northern Chile, has recently started operating as an underground mine using the Block Caving method. In this work, a new mathematical model is proposed to explain the phenomenology observed in the gravitational flow of fractured rocks in block caving mining...

... ABSTRACT: Wallonia and Hauts-de-France regions encounter complex developments of multi-level mining cavities that may affect the stability of shallower ones. This work focusses on an abandoned room-and-pillar quarry that extracted phosphatic chalk. On the same site, coal was mined out...

... ABSTRACT: It is known that the ratio of rock stiffness around the mine workings and the stiffness of the surrounding strata has a crucial meaning for rock stability in the close vicinity of the underground excavation. Significant resources were invested for the research aiming to understand...

... Abstract This study deals with the field application of the microseismic monitoring techniques in an underground mine. There was a rockfall accident during microseismic monitoring. The measured MS signals in this study were mainly divided into signals by blasting, drilling, electrical noise...

... Abstract Backfill as a substitute of ore body can reduce the ground subsidence and transfer the stress of surrounding rock mass. It was most important to keep the backfill stable in mining activities. Past decades, many researchers analyzed the stability of backfill considering it as block...

... Abstract Blasting is a needed activity when mining in hard rock excavations. Activities involving explosives may cause damage in the neighborhood, especially because of its vibrations and noise propagation. This paper describes a monitoring done in an urban area near of a small open pit mine...

... ABSTRACT Increasing the mining depth at LKABs Kiirunavaara mine located in the northern part of Sweden is leading to higher stress magnitudes, resulting in increased seismic activity and more rockburst damage. The effectiveness of various ground support systems under dynamic loading conditions...

... ABSTRACT The formation of large disturbed areas around coal mining activities, including sublevel coal extraction directly or indirectly influence the surrounding rocks and soils. Even though the analytical methods for determining these impacts are not strictly determined, the elastic...

There is a consensus on the need for new approaches in the design, operation and decommissioning of workings made on, or within, rock masses, so nowadays geologists, engineers, designers, constructors...

... ABSTRACT: Mining represents a major application of the discipline of rock mechanics. In fact, rock mechanics may be regarded as the basic mining science. Particular rock mechanics challenges will be faced in engineering the next generation of extremely large underground metalliferous mines...

... Seismic integration schemes aim to incorporate the rock mass response provided by the historical seismic activity to improve the ability of numerical models to reproduce future response to mining. Up to now, integration schemes considered the events using quasi-static models. This paper presents...
