倾斜、缓倾斜中厚矿体在我国化工、有色、金属及其他行业的矿山所占比重较大。矿山开采实践表明,此类矿体较难开采,特别是倾角为30°～45°,厚度为5～10米的倾斜一缓倾斜中厚矿体,不管矿岩稳固与否,其开采难度更大。其主要原因是它只能部分地利用矿石自重运搬,底盘存矿既影响出矿效果又增加了底盘损失。
Inclined, gently inclined medium thick ore bodies occupy a larger proportion of mines in China’s chemical, nonferrous metals, metals and other industries. Mining practice shows that it is more difficult to mine such ore bodies, especially for inclined moderately inclined moderately thick ore bodies with a dip angle of 30 ° -45 ° and a thickness of 5 to 10 meters. No matter whether the ore rock is stable or not, its exploitation is more difficult Big. The main reason is that it can only partially use the transport of ore by its own weight. The deposit of the chassis not only affects the mining effect but also increases the chassis loss.
