山东省莱州市仓上金矿为提高爆破质量和效率，减轻爆破震动，最大限度地降低生产成本，研究出在国内同行业属领先水平的“炮孔底部垫层水介质爆破技术”，并成功地推广应用，效果良好。仓上金矿露天采场深孔爆破生产过程中，９５％以上的炮孔为水孔，水深１－８ｍ以上。炮孔深 In order to improve blasting quality and efficiency, reduce blasting vibration and minimize production costs, Cangshang Gold Mine of Laizhou City, Shandong Province has developed a “blasting technology of under-cushion water blasting at the bottom of blasting hole” in the same industry in China and succeeded To promote the use of good results. During the deep-hole blasting process in the open pit of Cangshang Gold Mine, more than 95% of the blast holes are water holes with a depth of more than 1 to 8 meters. Gun hole deep
