江西德兴铜矿研究采用聚能爆破法破碎大块矿岩,获得了成功,最近通过评审,并已推广应用。破碎大块矿岩,传统的方法是打眼放炮,劳动强度大,也较危险。该矿推行的聚能爆破法,是将聚能药包用支架撑着放置于大块的表面(药包不与岩石接触),靠药包爆炸时产生的高速、高温射流来破裂岩石。经实践证明,此法破碎效果理想,爆
Dexing Copper Mine in Jiangxi Province has used the blasting method to crush large ore rocks and gained success. It has recently passed the assessment and has been popularized and applied. Broken large ore rock, the traditional method is to hit the eyes blasting, labor-intensive, but also more dangerous. The blasting method adopted by the mine is to gather the polypharmacological medicine package with the supporter and place it on the surface of a large piece (the medicine bag does not come into contact with the rock) and break the rock by the high-speed and high-temperature jet generated when the medicine bag explodes. Proved by practice, this method crushing ideal, burst
