摘要
安庆铜矿大直径深孔采矿法进行的宽孔距爆破漏斗试验，是以单孔爆破漏斗试验为主体，双孔为辅，得出了大孔爆破孔网参数的设计依据。提出了孔距与最佳爆破漏斗半径之比（Ｋ值）的选取范围。所述内容体现了未来爆破漏斗试验的新思路，具有较强的实用性，能较好地满足矿山生产的需要。
Taking experiments on single-hole blasting crater as main but two-hole blasting crater as supplement, the experiment on large holespacing blasting crater for large-diameter longhole mining in Anqing copper mine provided a basis for the hole pattern parameters design of large-diameter longhole blasting, and a selected range of holespacing-to-optimal blasting crater radius ratio (value K). This paper presents a new thought train on the futural blasting crater experiment, which is of better practicality and can meet the requirements of mining production satisfactorily.
