平行束状深孔爆破技术的研究

束状深孔是一种新颖的崩矿技术，国内外都进行了束状深孔爆破技术试验研究，并成功地应用于矿山生产，获得了预期效果。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，在矿山围岩稳定性差的条件下更适合采用。本文主要介绍束状深孔爆破机理，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。

STUDY ON PARAMETERS OF PARALLEL BUNCH-LONG-HOLE BLASTING TECHNIQUE

Bunh-long-hole blasting is a new kind of blasting technique. Tests and studies on bUnch-long-holeblasting un made at home and abroad, and the new technique bas been successfully used in mining produc- tion with desired results achieved. It is proved by practice that the new technique with high breaking efficiency , good safety can be ed under the condition of poor rock stability. In this paper, the calculation and selection of balsting parameters and its application in mining production are described. Theblasting effect is also analyzed in the paver.
