群柱状药包同段爆破

GROUPED EXPLOSIVE COLUMN SAME MILLISECOND BLASTING

多排同段爆破技术,是铜陵有色金属公司狮子山铜矿技术人员,从1967年开始,经过于20多年的生产实践,进行了近千次大爆破,不断探索、完善而创造出来的一种新技术、新工艺。应用新爆破参数,将同段毫秒雷管引爆群孔药包,使爆破能同时对岩层作功,并延长作功时间,提高了爆破功有效利用率。这项爆破技术,是以柱(ZHU)状药包,同(TONG)段爆破为特点,简称“Z·T”爆破法。适用于各种矿岩,各类炸药,各大、中、小直径炮孔,各种采矿方法的采场落矿。

Multiple row same millisecond blasting is a new technique, new technology, resulted by sustained seeking and improving efforts of the technician of Shizishan Copper Mine in more than 20 years' practice for about thousand times of large scale blasting since 1967. Applying new blasting parameters, igniting the same-millisecond detonator for grouped holes blasting, enable the work of blasts to act simultaneously on the rock, the work duration to be prolonged and the effective utilization of blast work to be increased. This blasting technique, called by name'Z · T blasting 'according to Chinese initialism ,is applicable for various ores and rocks, for various explosives, for large, medium and small blastholes and for caving by various mining methods.
