一、改建露天金属矿中所出现的采空区的危害对于这种由井工矿井改建成的露天金属矿,由于金属矿在地下的附存分布基本为条带状(矿脉形状较为规则,开采较为容易)和块装(矿脉形状极为不规则,大部分成鸡窝装分布,开采难度较大。)两种。所以在改建的同时应当对其矿脉的产状有一个细致的了解,并对其金属的性质(是否有放射性,是否会伴有有毒气体的产生等)作一个详细的地质分析,这些对于我们在露天
First, the alteration of open-air metal mine in the mined area hazards For this mine converted from open-pit metal mine, due to the distribution of metal deposits in the ground basically strip (veins more regular shape, mining more Easy) and block loading (veins extremely irregular shape, most of the distribution into the chicken nest, mining more difficult.) Two. Therefore, at the same time of remodeling, we should have a detailed understanding of the shape of its veins and a detailed geological analysis of the properties of the metal (whether radioactive or not, accompanied by the generation of toxic gases, etc.) open air
