An Anatomy of a Seismic Sequence in a Deep Gold Mine,gnitude from −0.5 to 3.1 were recorded and located by the mine seismic network. The sequence lasted 12 days and was composed in fact of four main shock-aftershocks sequences, closely following each other in space and time. The events were confined to a volume of rock extending to 670 m in the N-S, 6

Scaling Laws for the Design of Rock Support,st step in the design of systems for the support of openings subject to such loading is to assess the ground motion characteristics; i.e., to evaluate the peak particle velocity . in the design region. Design scaling laws, relating seismic source intensity (event magnitude, radiated energy or a comb

Predisposition to Induced Seismicity in Some Czech Coal Mines,o establish the conditions leading to a focal zone generation. The study, based on macroseismic and instrumental observations, proved that seismicity is influenced by natural as well as mining conditions. The first group includes the influence of faults, washouts and red beds, while the second one i

Spatial Distribution of Mining Tremors and the Relationship to Rockburst Hazard,is study is to characterise and analyse the induced microseismic events during the mining operations, in order to identify or establish criteria for the zones likely to generate rockburst. The detailed study of the space distribution of microseismic events enables consistent correlations to be demon

Induced Seismicity in Liaoning Province, China, earthquakes. A shock with magnitude . = 5.2 took place on December 22, 1974 at Shenwo Reservoir and some smaller earthquakes caused by impoundment also took place near other reservoirs. Numerous earthquakes associated with mining activity occurred in some coal mines. 56 collapse earthquakes with ma

Delineation of Active Faults, Nucleation Process and Pore Pressure Measurements at Koyna (India),. 6.3 earthquake which claimed over 200 human lives and destroyed the Koyna township. Earthquakes of . ≧ 4 occur every year following an increase of water level in the reservoir. During 1973, 1980 and 1993–94 earthquakes exceeding magnitude 5 occurred. Most earthquakes of .≧4 are associated with pro
