爆破振动速度在竖直向有放大效应，对于距爆源等距离的竖直向的爆破振速大于水平向。
Blast vibration velocity has magnify effect in the vertical direction, the vibration value of vertical direction is bigger than horizontal direction at the same distance to blast place.
根据质点振速的安全控制标准，确定了不同药量爆破的震动安全距离，以及确定距离的安全药量。
The shocking safety distances for blasting with various charges and safe charge for specific distance are both determined according to the particle vibration velocity safety control standard.
结果表明应用该方法和运用《爆破安全规程》（GB6722-2003）并以振速作为判据所得的评价结论能取得一致。
The results indicate that the assessment conclusion educed form the application of this method and application of the《Blasting Safety Regulations》(GB6722-2003) are consistent.
