Selection of Reasonable Millisecond Interval for Jinduicheng Open-pit Molybdenum Mine
How to reduce the blasting vibration should be counted as the main safety issues for mine. Waveform interference for vibration reduction can achieve active control to the blasting vibration, and a reasonable millisecond delay interval is the core of waveform interference for vibration reduction. With the help of MATLAB programming, this paper was carried out the superposition for the blast vibration signal tested in blasting locale, simulate the blast vibration effect under different millisecond interval through computers, and select the reasonable millisecond interval to achieve the purpose of blasting vibration reduction. This method should be applied to Jinduicheng open-pit molybdenum mine，a reasonable millisecond interval for this mine has been proposed, and the blasting vibration has been reduced.
