| Abstract: | Regarding the preventative protection from blasting harm in underwater drilling,waveform curves and pressure data of shock wave were practically measured through testing of underwater drilling blasting in shallows at seashore,with the two popularly used measures,titled millisecond blasting and bubble curtain,for weakening the negative effect being discussed and verified. The test results showed that proper employment of millisecond blasting could enable the total explosion energy to disperse rationally according to time,while bubble curtain could only show its weakening affect on some shock waves of specific frequencies. The paper presented plenty of valuable experience for further study. |
