本文试图借鉴经济发达国家的经验,在我国露天铁矿总体规划的背景下,根据开采工艺的客观要求和钻机结构的特点,对我国露天铁矿穿孔技术的发展作一预测。一、对大型牙轮钻机的需求将持续增长近三十多年来,国外金属矿山尤其是铁矿山采矿技术发展的总趋势是,开采方法以露天为主,露天开采生产高度集约化,发展了高效、耐用的大型采掘运输设备。大型设备是露天开采生产高度集约化的物质技术基础。露天
Based on the experience of economically developed countries, this paper attempts to predict the development of perforation technology of open-pit iron mines in our country under the background of the overall planning of open-pit iron ore in our country, according to the objective requirements of mining technology and the characteristics of rig structure. First, the demand for large cone drill will continue to grow Over the past 30 years, the general trend of the development of mining technology in foreign metal mines, especially iron mines is that the mining method is mainly open-air, open-air mining production is highly intensive and development Large, efficient and durable mining and transportation equipment. Large-scale equipment is the material and technological basis for the highly intensive production of open-pit mining. open air
