用露天开采法开采的煤田具有各种各样的矿山地质条件的特点。在露天采矿工程中,主要利用高效率挖掘机、重型运输和辅助设备。在这些条件下,改进采矿工艺是提高生产经济效益和劳动生产率的先决条件。 露天开采科学研究所正在解决改进露天矿采煤工艺的问题。这里,特别重视采用重型挖掘机、采用新技术装备的矿山运输工艺的科学论证以及研究对矿山企业环保的新要求。 在考虑露天矿生产准备中合理组合采矿和运输设备的基础上,制定典型的剥离和采煤工艺方案乃是研究的重要方向之一。综合研究的方向是,确定间断的运输和无运输开采方法的合理的技术参数;对生产条件有变
Coal mining with open pit mining has the characteristics of a variety of mine geological conditions. In open pit mining, the main use of efficient excavators, heavy transport and auxiliary equipment. Under these conditions, improving the mining process is a prerequisite for improving the economic efficiency of production and labor productivity. Open-pit Mining Research Institute is addressing the issue of improving the coal mining process in open-pit mines. Here, special attention is paid to the scientific justification for the use of heavy-duty excavators, new technology and equipment for the transportation of mines, and new requirements for the environmental protection of mining enterprises. On the basis of considering the reasonable combination of mining and transportation equipment in preparation for the production of open-pit mines, it is one of the important research directions to develop a typical stripping and coal-mining scheme. The direction of a comprehensive study is to determine the reasonable technical parameters of intermittent transport and non-transport extraction methods; to change the production conditions
