摘要
通过远距离爆破切割技术回收江底穿孔钻具的实际例子,介绍了在复杂的江底土岩条件下实施钻杆聚能切割的爆破技术的原理、关键参数,并阐述了在地表进行模拟爆破切割试验的效果及实际操作中应注意的问题,值得同行参考。
The principle of blasting along with the key parameters used in an actual operation in the case of recycling the drilling tool under riverbed through cumulative energy cutting blasting at long distance was discussed in this paper. The operation was tested on ground for simulation of the effects of the blasting cutting and for finding the problems that should be taken care in actual execution of the blasting. The work done in this paper is of reference value to the similar engineering.
