摘要: 以郑家坡铁矿采矿方法优化为工程背景,通过对缓倾斜中厚矿体、顶板不稳固、易透水、大水、矿床松软、夹石多而矿体破碎的地质情况的综合分析,提出了分段菱形矿房嗣后充填法。该采矿方法适合于矿体厚度为6~15 m,倾角10°左右的部分(可以视为缓倾斜中厚矿体),夹石在开采过程中部分剔除,损失和贫化趋于中等平衡,对提高该矿的产量和促进安全生产具有实际意义。

Abstract: With the mining method optimization of Zhengjiapo Iron Mine as engineering background, the diamond room sublevel stripping with backfilling is put forward through analyzing the geological features of the gently inclined medium-thick ore-body, such as unstable roof, easily flooding, big water yield, loose deposit, much blocks and broken ore-body.The mining method is suitable for the parts of ore-body with thickness of 6~15 m at dip angle of about 10°, which belongs to the gently inclined medium-thick ore-body.Some stones are removed in the mining process, and loss and dilution tends to be medium balance.This mining method is of great significance to increase the output of the mine and safety production.

Key words: Roof breakage, Refractory ore-body, Mining method, Diamond room sublevel stripping with backfilling
