使用地下法或联合法开采金属矿床时,特别是在山区,常常用深溜井把矿石运到集运水平或主运水平。根据“钼”矿山深溜井大量生产经验,便可对深溜井的各种结构和生产方式作出评价。“钼”矿山开采若干个绝对标高为2000～3100米的急倾斜矿体。这些主要矿体呈石榴石矽卡岩、石灰矽卡岩、硫化矽卡岩和辉石-闪长片麻角岩,这些岩石的紧固性高且稳定。在矽卡岩矿体的上盘是不稳定的
When using the underground method or the joint method to extract metal deposits, especially in mountainous areas, the ore is often transported to the catchment level or to the main transport level by using the deep-draw well. According to “Molybdenum” deep-well mine production experience of a large number of wells, we can make a variety of deep-well well structure and production methods to make an assessment. “Molybdenum” mining a number of absolute elevation of 2000 ~ 3100 meters of steep inclined ore body. These main ore bodies are garnet skarns, lime skarns, skarn skarns, and pyroxene-dioritic amphiboles, which are highly anchorable and stable. The top plate of the skarn ore body is not stable
