Semen Baturaja Persero, Tbk is one of the companies engaged in the production of cement that takes raw materials through limestone mining process located in Baturaja City, OKU Regency, South Sumatera Province. Limestone mining activities use blasting activity that produces blasting effects and flyrock. Measurements of vibration and flyrock frequencies obtained a maximum value for vibration of 4.66 mm/s and predicted farthest distance of flyrock above 170 m when powder factor exceeds 0.1 kg/m3. The results of the data show that the level of emission has exceeded the standard limits for second class buildings (3 mm/s) based on (SNI) 7571: 2010. Blasting just 175-300 m from the nearest settlement and already exceed the save distance for equipment 300m and 500m for human activity based on USBM (United States Bureau of Mines). To reduce the vibration level, the maximum number of mass per delay is 43 kg/delay with PPV parameter 3 mm/s at 170m distance. Actual factor powder should not exceed 0.1 kg / m3 to minimize flyovers in safe zones not exceeding 150 m.
