沟槽控制爆破研究技术

Studies on the controlled blasting techniques in theditching engineering

文章通过对洋浦电厂海水冷却箱涵沟槽预裂（深孔）爆破技术的研究，提出了复杂地质条件下合理的控制爆破参数及微差起爆方式。针对砂层地段难以钻、爆的特点。笔者进行了有益的探讨。

This paper researches the Yangpu power station cooling waterculvert presplit and deep-hole blasting techniques.It reports theresonable controlled blasting parameters and millisecond delay blastingway under the complicated geologic conditions. the characteristics ofdrilling and blasting in the sand area are alao studied.
