摘要
通过单孔爆破漏斗试验,使极难爆破岩的大块率高、岩根多等问题得到有效解决,为寻求合理的孔网参数提供依据,解决生产中铲、装、运效率低和生产成本高等难题,为灵活运用"小排距,大孔距"爆破方法提供可靠基础。
The simple hole crater test can solve the problems about the rate of massive ore of the hard ore rock and the root of the rock efficiently The test gives us reasonable proof about the holenet parameter It can also solve the problems of the low efficiency and high cost during the production It offers us reliabie base on how to usr the biasting of the small row pitch and the big holepitch.
