| 摘 要： | 束状深孔爆破是一种新颖的崩矿技术。１９８６～１９９０年进行了束伏深孔爆破技术的试验研究，并成功地应用于矿山生产中，获得了预期的效果。实践证明：束状深孔爆破技术具有崩矿效率高、安全、爆破成本低等显著特点，在挤压爆破条件下更适宜采用束状深孔爆破技术。笔者简要地介绍了束状深孔爆破机理的基础实验、爆破参数的选取及爆破技术的实施，并对爆破效果进行了分析。

| Abstract: | Bunch-long-hole blasting is a new kind of blasting technique.From 1986 to 1990,tests and studies on bunch-long-hole blasting were made.After that the new technique has successfully been used in mining production with desired results achieved.It is proved in practice that the new technique features high bursting efficiency,good safety and low blasting cost.In this paper,basic tests on the mechanism of bunch-long-hole blasting are outlined,calculation and selection of blasting parameters,and its application to mining production are described with blasting effects analysed. |
