The theory and system for preventing rock burst in large-scale areas
Abstract：Pointed out that the mining of region-wide has a close relation with the form of concentrated static load, nee- ded by locally rock burst to occur. An regional preparedness idea of rock burst was brought forward, which based on the concept of dredging method of wide concentrated static load. Analysed the feasibility of adjust and effect law of high concentration stress of rock burst coal bed, by theoretical analysis and numerical simulation. It is indicated that the system of regional preparedness of rock burst, which based on the burst seam identification, stress testing, mining method selection, roadway location identification, protection layer mining and the orderly mining of the same coal bed, can avoid or reduce the high stress concentration. The study results give a guidance for design stage of the new mine, new mining area or new level design phase of producding coal mining to prevent rock burst.
