“…Finally, rock bursts can be caused by the presence of faults, dykes, or joints. mining induced stress fields as well as new catastrophic dynamic phenomena (of which a rock burst is the most unpredictable and violent ( [3]; [4]). Thus mining depth is directly related to hazards, especially for rock bursts.…”

Rock bursts and mining-induced seismic events have serious socio-economic consequences for the Chinese mining industry, as its mines are extended to a specific depth. This paper mainly discusses deep mine hazards and rock burst problems in China. First, the definition of a 'rock burst' is given. The paper also introduces the current situation of deep mining and predicts its influences in Ivory Coast over the next ten years. Second, it explains the dynamic hazards arising from deep mining (the most dangerous hazard in deep mining in China).It then emphasizes that dynamic hazard control is a complex technology system that involve many techniques: evaluation, control, prevention and treatment. The burst technique system involves devices that are highly complex. Finally, the paper presents cases of controlled rock burst using the control technologies described, and considers their applications in Ivory Coast's deep mining industry.

“…These techniques have been used extensively and successfully in the Earth Sciences to map characteristics of the Earth at great depths, for example, the identification of the Mohorovicic Discontinuity (Moho); see Rawlinson et al (2010) for a description of the history of tomographic techniques. To a lesser extent, these techniques have been applied in the mining environment, which is at a much smaller scale, where correlations between velocities and i) geomechanical characteristics of the rock mass (Cai et al 2014;Hemmati Nourani et al 2017;Watanabe and Sassa 1996), and ii) stress anomalies (Cao et al 2015;Friedel et al 1995Friedel et al , 1997He et al 2011;Hosseini et al 2013;Krauß et al 2014;Luxbacher et al 2008;Ma et al 2016;Young and Maxwell 1992) are evaluated. Much of this work was conducted in soft rock environments (coal mines).…”
