Abstract: For making study on the high-position hard strata mevement caused mine earthquake occurrence, transmission, its response, and induced rock burst more systematic, Dongtan coal mine 43_up13 working face was taken as an example,of which theoretical analysis, field monitoring and numerical simulation were carried out.A method,taking into account the hypocenter size,was worked out for describing mine earthquake transmission characteristics. The results show that the high-position hard strata movement is the main power source of high energy mine earthquake,that the hypocenters distributed along with the faults,that the amplitude of supporting resistance and frequency become higher before or after mine earthquake,that the cycle characteristic of high energy mine earthquake is manifested by a small cycle of 50 m in a big cycle of 100 m,that four high energy mine earthquakes occur in a big cycle,that the mine earthquake's dynamic response can be picked by multi parameter monitoring, and that the mechanism,by which a rock burst disasters is induced by mine earthquake,is that the different between the energy gathered and consumption in burst zone is increased by mine earthquake,and the rock burst will occur when the stiffness conditions are satisfied.

Key words: high-position hard strata, coal mine earthquake, rock burst disasters, transmission characteristics and its response, instability criterion
