Effects of Blast Vibration on Unplanned Dilution in an Underground Metal Mine
One of the factors affecting overbreak or slough of the roof and walls of underground stopes, causing unplanned dilution is blast vibration. The amount of damage caused by earth vibration can be measured in terms of peak particle velocity (PPV). In this study, in order to investigate the effects of blast vibration on the occurrence of unplanned dilution, 72 three-component records acquired upon...
متن کاملNumerical modelling of the underground roadways in coal mines– uncertainties caused by use of empirical-based downgrading methods and in situ stresses
Numerical modelling techniques are not new for mining industry and civil engineering projects anymore. These techniques have been widely used for rock engineering problems such as stability analysis and support design of roadways and tunnels, caving and subsidence prediction, and stability analysis of rock slopes. Despite the significant advancement in the computational mechanics and availabili...
متن کاملVibration Attenuation by Periodic Foundations
Vibration attenuation to horizontal propagating waves by using periodic foundations is investigation. Periodic structure theory is introduced to design a new type of isolation foundations, which has a special frequency band gaps (or ‘attenuation zones’) that can barrier waves/vibrations propagation. Materials usually used in civil engineering are used to fabric periodic foundations with the uni...
متن کاملVibration Generated by Underground Railway Trains
The control of vibration generated by railways in tunnels is complicated by the dynamic interaction between tunnel and track. Conventional methods (floating slab track, ballast mats, under-sleeper pads) do not perform as well as might be expected and it is the purpose of this paper to explore the sources of error. The major factors which must be taken into account pertain to the three-dimension...
