应用联合切割机的连续采运新工艺从70年代末起已在世界非硬岩露天开采中得到了广泛应用。因为它把松动、回采、装载、破碎和胶带输送等工艺融为一体,从而解决了传统的爆破-装载-胶带输送采矿工艺带来的缺陷。借鉴世界对联合采矿机组在露天开采的使用经验,原苏联从1989年也开始采用此项工艺,用于开采石膏、大理石、石灰石等。介绍了世界上联合采掘机的主要生产厂家、机械类型和型号、价格及其应用效果。还提到了斗轮挖掘机-转载机-输送机-排土机系统。上述这些成熟的应用经验和配套设备也将为硬岩开采提供了理论上和心理上的准备。
The new technology of continuous mining using the cutting machine has been widely used in the non-hard rock open pit mining in the world since the late 1970s. Because of its loosening, mining, loading, crushing and tape conveyor and other processes integrated, thus solving the traditional blasting - loading - tape delivery mining process brings the shortcomings. Drawing on the experience of the world in using open-pit mining units, the former Soviet Union also adopted this process from 1989 for the exploitation of gypsum, marble, limestone and the like. Introduced the world’s major mining excavator manufacturers, machinery type and model, price and application effect. Also mentioned bucket wheel excavator - loader - conveyor - Dump machine system. The above mature application experience and supporting equipment will also provide theoretical and psychological preparation for hard rock mining.
