Deep-hole directional fracturing of thick hard roof for rockburst prevention

Tunnelling and Underground Space Technology, 2012
Abstract Thick hard roof in coal mines is usually a significant factor that induces dynamic disasters, such as rockburst. This study introduces a new technology called directional hydraulic fracturing characterized by cutting out an initial groove in the borehole and then injecting high pressure liquid to break the rock.

Rockburst hazard evaluation and prevention methods in Polish copper mines

2011
Longstanding mining of copper deposit in the Legnica-Glogow Mining Basin (LGOM area) enabled to gain broad experience concerning the impact of geological and mining conditions on seismic and rockburst hazard. Basing on gathered data, the methods of rockburst prevention for deep copper mines were developed. Methods of rockburst hazard evaluation as well
