Research on the Mechanism and Prevention of Rockburst at the Yinxin Gold Mine

Journal of China University of Mining and Technology, 2007
Abstract The occurrence and nature of shaft rockburst in the Yinxin gold mine are recorded and analyzed. Rockburst happens along an obvious south-north orientation. The ground and surrounding rock stresses are measured in this mine. The research indicates that the directivity of rockburst is closely related to geological structure and to abnormal ...

Intense rockburst impacts in deep underground construction and their prevention

Canadian Geotechnical Journal, 2015
In the last few decades, in both mining and civil engineering projects, deeper excavations have been carried out than in the past. With this increase in depth, rocks may overstress and rock failures can occur during excavation. When competent rock strata are encountered under high stress conditions, these failures can vary from superficial spalling to

Prevention of rockburst by guide holes based on numerical simulations

Mining Science and Technology (China), 2009
Abstract We studied variations in the stress field around guide holes drilled during tunnel excavation to understand the mechanical mechanism by which these holes help prevent rockburst. The study used elasto-plastic analysis of a circular chamber under non-axisymmetrical loads.

The Study on Prevention of Rockburst When Mining in Folding Structure Areas

2011 Asia-Pacific Power and Energy Engineering Conference, 2011
In order to discuss the relation between rock burst and stress field in folding structure areas, the law the changing law of local stress area induced by mining was studied by FLAC2D simulation procedure and the targeted prevention measure was proposed from a strategic defense view based on the characteristics of rockburst in fold areas.

Applicability of energy-absorbing support system for rockburst prevention in underground roadways

International Journal of Rock Mechanics and Mining Sciences, 2020
Abstract Rockburst is one of the leading disasters in mining and rock engineering causing serious casualties and property losses. A major engineering challenge for underground roadways in mines experiencing significant seismicity is the performance of the support system.

Rockbursts in Coal Mines and Their Prevention

2017
The preventive methods described have proved highly effective. They comprise laying out the workings in such a way as to minimize dangerous concentrations of ground stresses, and early elimination by means of blasting, drilling, or water infusion. An account of these methods as applied in German coal mines, the deepest in the world.
