Status and Control Measures of Rock Burst in Phosphate Mines in Western Hubei
Based on the in-depth investigation of the geological characteristics of the phosphate mines in western Hubei,including Sujiapo Phosphate Mine,Maping Phosphate Mine and Taoyuxi Phosphate Mine,rock burst phenomena were analyzed in terms of influencing factors of occurrence position,buried depth and lithology.The appropriate control measures are proposed for rock burst in those phosphate mines in western Hubei.In-situ stress of underground phosphate rock in western Hubei was tested.Based on the obtained results,the mining sequence was optimized to avoid mining operation in the stress concentration area as much as possible,and pressure relief and support measures were taken in local areas to ensure safe underground mining.
