由于露天矿深度的增加,矿山地质条件恶化、岩石硬度、组合强度和涌水量增大,并使矿山运输工作复杂化,剥采比和剥离量增加、以及远距离运输等。这对改进剥离工作造成很大困难。随露天矿的延深,欲想得到高质量的破碎矿石和理想的塌落参数变得相当复杂,特别是对矿床开采的运输系统,塌落参数有其重要意义。第一乌拉尔露天矿对开采辉长石和角闪
Due to the increase of the depth of the open pit mine, the geological conditions of the mine are deteriorated, the hardness of the rock, the combination intensity and the influx of water increase, the operation of the mine is complicated, the stripping ratio and the amount of stripping are increased, and the long distance transportation and the like are carried out. This has caused great difficulties in improving the divestiture. With the deepening of open-pit mines, it becomes quite complicated to obtain high-quality broken ores and ideal slump parameters, especially for the transportation system and slump parameters of the ore deposits. The first Ural surface mine on the mining of feldspar and horn flash
