One of the blast effects is ground vibration. Ground vibration caused by blast wave propagation and it causes rocks to break. If the blast is not well controlled, it does fatality for employees, infrastructure, and equipment damage. For that reason, blast needs a good plan and well monitored. The micro-seismic method can use for analyzing the blasts effect based on the recorded wave in each sensor. The physical properties known from waves are peak particle velocity and seismic moment. The analysis will use for estimating the minimum secure distance from the blasting point, the blasts effectiveness, and maximum crack distance influence. A minimum secure distance criterion is distance where the recorded wave has a maximum peak particle velocity of 150 mm/s. The most blasts effective is where the seismic moment number is higher than others. Using nine blasts in the panel and 16 blasts data in undercut from 28 March-11 July 2018, were then be analyzed, and the results are: the variation of secure distance is 1-12 m for panel and 1-17 m for an undercut. The maximum crack effects of blasts are 35m for panel and 51m for the undercut. The most effective of the blast was a panel at P#10-11 DB#7, and undercut at DD#13 WS R#102-105. Therefore, micro-seismic data are instrumental in determining safe conditions in the underground mine blasting process
