Abstract
Aiming to the increasing rock burst disaster which severely threaten the safety production in Huating coal mine as deep mining,integrated monitoring methods such as acoustic emission,micro seismic,electromagnetic emission and drilling were adopted in this paper,and on this basis,roof and floor deep hole blasting,coal seam pressure-relief blasting,drill-hole pressure relief are used for prevention in order to weaken the impact strength and achieve the integrated control of rock burst.
