根据矿体类型不同,大理石矿山可分成山坡露天开采、凹陷露天开采、井式开采和山洞式开采等类型。但随着矿体产状的延伸、品种的变化,一些露天矿山在开采的推进过程中会遇到极大的困难和障碍。例如,一些山形异常陡峭,剥离量巨大、开采作业极度危险的山坡露天型矿山,像四川省宝兴县的一些大理石矿山就属于这种类型。还有一些倾斜矿体的凹陷露天型矿山,其矿体深深地斜插入地下,继续开采,
According to different types of ore bodies, marble mines can be divided into hillside open pit mining, open pit mining, pit mining and cave mining and other types. However, with the extension of ore body shape and varieties, some open-pit mines will encounter great difficulties and obstacles during the process of mining. For example, some types of hillside open-pit mines, such as steep mountain ranges, huge amounts of peel, and extremely dangerous mining operations, like some marble mines in Baoxing County, Sichuan Province. There are also some inclined ore body open pit mining, the ore body obliquely inserted into the ground, continue mining,
