Abstract
Today one of the world’s largest coal mining producers is China. Mining, especially coalmines had been the major sources of income to Chinese people. The mining activity offers many great opportunities to country and its population. Unlike in Ivory Coast where the active involvement of many people in artisanal mining activities in Ivory Coast is mainly due to the high rate of abject poverty and the low price of agricultural produce. With the increasing depth of mining, rock burst is on the rise. China’s deep mining industry faces such a threat. A major problem of deep mining is high ground stress, which is the major factor of rock burst. Due to the complexity of the rock burst mechanisms, complexity of induced factors as well as suddenness and randomness of rock burst occurrences, studies of rock burst prediction and control for safe mine exploitation is far from satisfying. The purpose of this paper is to examine of rock burst phenomenon in order to understand both stability in rock mechanics and the prediction of instability disasters in rock mechanics for application in the Ivory Coast mining sector with reference to the current Chinese mining industry.

Key Recommendations
It will be useful to suggest some recommendations that lead: (1) To isolate the coal, to stop line ready seam roadway distance within the range of over 450 m, and be focused by putting on a layer or floor coal area for investigation, and the impact of risk assessment; (2) To develop and scour protection measures against “high stress isolated coal partial creep overall instability coupled with the impact of” complex dynamic disaster, after the implementation of the experts; (3) To prepare Roadway take microseismic monitoring, real-time online monitoring stress, the cuttings were monitored in order to determine the reasonable stopping line location, evaluate the impact of real-time ready within seam roadway to provide risk basis within the Mining Area first (4) To resume production of all the mining area must focus on the mountain roadway, try to find the impact of the current location and the danger zone of risk, and then determine resume production program.
