Ortlepp Integration of deterministic modelling with seismic monitoring for the assessment of rockmass response to mining: Part I Theory. Rock burst events can be induced from blasting to induce failure in the surrounding rock, rendering it unable to retain high loads, thus decreasing the event magnitude. Continuous Monitoring. As mining progresses, the stresses and seismic failure mechanisms present will evolve.

    Stresses around mine openings at depth can cause the surrounding rock to fail, releasing stored strain energy. When this happens, the rock may literally explode or "burst" into the opening without warning. As mining progresses deeper into the earth, the possibility of seismic events and rock bursts increases.

Highly stressed rock in stopes continues to be a primary safety risk for miners in underground mines because this condition can result in failures of ground that lead to both injuries and death.

Sincethe ACG have been involved in research into the mitigation of economic and safety risk associated with seismic risk in hard rock mines. The ACG’s Mine Seismicity and Rockburst Risk Management Project is currently in its 5th phase, with previous phases of the project documented in MERIWA reports M, M, M and M Survey data included rock burst damage reports, seismic event locations and magnitudes and, for the most energetic events, first- motion information.

Several subsets of this database, including large seismic events, rock bursts, and microseismic activity near the face, were analyzed. This book grew out of Mine Seismology: Glossary of Selected Terms, presented at the 8th Symposium on Rockbursts and Seismicity in Mines (RaSiM8) in St.

This book illustrates how mine seismology can be used to improve underground safety standards. It describes several preventive actions that have been put into practice at the 5B Area of No. 5 Shaft Vaal Reefs gold mine after issuing seismic warnings.

The following provides an example of 3-D seismic imaging of VMS deposits in the Flin Flon mining camp in Manitoba, Canada (Malinowski et al., ; White et al., ).The Flin Flon mining camp in Manitoba is located within the Paleoproterozoic Flin Flon metavolcanic belt and is close to the town of Flin Flon, Manitoba, near the Saskatchewan border at ~ 55° north.

In MaySpringer published his first book entitled "Mine Seismology: Data Analysis and Interpretation.".

Routine seismic monitoring in mines was introduced over 30 years ago with two main objectives in mind: • immediate location of larger seIsmIC events to guide rescue operations; • prediction of large rockmass instabilities.

The first objective was achieved fairly quickly, but with the subsequent development of mine communication systems, its strategic importance has diminished.

Similar basic seismic data for rock burst-prone mines in the Republic of South Africa can be found in papers by Cook (2), Wodgson (3), McGarr (4), and Lenhardt ().

The instrumentation, the method of locating the events, and the development of a local magnitude scale are fust described, and then the seismic and rock burst data are. In many deep mines, dynamic rock mass failures, also called mining-induced seismic events, have become a major operational risk.

Seismicity and rockbursting is widespread in the Canadian mining. Abstract. The author analyzes the physical sense of the seismicity characteristics most often used in assessment of failure hazard in mines.

The seismic event is automatically processed, and seismic source parameters (including the location, time, radiated seismic energy and co-seismic inelastic deformation) are automatically calculated. This seismic data is regularly transferred to IMS’s offices for processing and.

Mining-induced seismic hazard assessment is an important component in the management of safety and financial risk in mines. As the seismic hazard is a response to the mining activity, it is non.

Predicting Dangerous Seismic Events in Active Coal Mines Through Data Mining. that is also called a rock burst [3]. bursts, or bounces, have been recognized as a serious problem in mining for more than 75 years. The analysis of historical seismic data shows a high correlation between observed mining seismicity and geometric.

A rockburst is defined as a mining-induced seismic event that causes damage to openings in the rock. In this literature report, mining induced seismicity is reviewed and the influencing factors described.

The state of stress is one important factor that influences the occurrence of. As production in large underground mines goes on to deeper, highly stressed levels, understanding and monitoring the seismic response of rock masses to massive mining.

Seismicity is often observed to occur during underground mining activities. This happens because the creation of mining voids (tunnels, stopes and excavations) changes the stress conditions in the rock. These stress changes may be large enough to fracture the rock, resulting in seismic evens.

Deeper mines generally experience a greater seismic hazard because of higher.Microearthquake activity associated with underground coal-mining in Buchanan county, Virginia, U.S.A. / G.A. Bollinger --The Alabama, U.S.A., seismic event and strata collapse of May 7, / L.T.
