Abstract


In this paper Longjiapu mine rockburst prediction and prevention were discussed in detail , pointing out that as China's increasing depth of coal mining , coal seam burial depth and complexity of the geological structure of the stress -induced burst become a major factor . Using electromagnetic radiation law and cuttings predicting rock burst , the first method of monitoring the impact of electromagnetic radiation hazards , and then drill cuttings France detection in hazardous areas impact the degree of risk , this integrated prediction method allows a more accurate prediction results and save time , improve face advancing speed. For the occurrence of rockburst areas appearing to take a local Jie Wei drilling relief measures . Quote rock failure process analysis software (RFPA2D), the scope of individual relief to simulate drilling , making holes relief programs more reasonable and applications in the field and achieved good results . In this paper, Longjiapu coal as the background, put forward practical burst prediction and prevention methods , under the same conditions as other mines of rock burst prediction and prevention of reference.
