NEGATIVE PRESSURE WAVE GENERATOR
PROBLEM TO BE SOLVED: To provide a negative pressure wave generator which can effectively reduce a micro barometric wave even in a negative pressure wave with a short time width.SOLUTION: A negative pressure wave generator 1 reduces the pressure of a micro barometric wave Wradiated from a mine mouth 21 of a tunnel 2 by means of a negative pressure wave W, and includes a plurality of negative pressure wave generation means 11 arranged in the vicinity of the mine mouth 21 and capable of radiating the negative pressure wave W, and control means 13 which controls operations of the plurality of negative pressure wave generation means 11 so that the negative pressure waves Ware superimposed on the micro barometric wave Wwith a time difference provided.SELECTED DRAWING: Figure 2
