近十多年来,我国露天矿穿孔工艺发展迅速,装备水平显著提高,穿孔已由露天矿生产薄弱环节一跃为最先进的工序;我国钻机、钻具制造业已经能够武装各种类型大至2000万吨级的露天矿山,有些设备的技术指标可与国际名牌产品媲美,矿用牙轮钻头、潜孔冲击器、钻头和小钎头已打入国际市场。我国露天矿穿孔技术的现代化面临广阔的前景。这是记者参加1986年10月20日至24日在南昌由
In recent ten years, the perforation technology of open pit mine in our country has developed rapidly and the level of equipment has been significantly improved. Perforation has been leapt from the weak link in the open pit mine to the most advanced procedure. Our country’s drilling rig and drilling tool manufacturing industry have been able to arm various types of large- 20 million tons of open-pit mines, some of the technical specifications of the device can be comparable with the international brand-name products, mining roller cone drill bits, down-hole impactor, bit and small bit has entered the international market. Modernization of perforation technology of open pit in our country faces broad prospects. This is a reporter who participated in Nanchang from October 20 to October 24, 1986
