煤与煤系共伴生矿产协调开采是国家重大战略需求。我国煤系共伴生有铝、铀、铁、镓等22种战略性金属矿产,种类多、储量丰富、与煤层叠置,赋存状态与开采方法差异大,各矿产开采的岩层活动、流体迁移等影响彼此正常开采。传统煤矿仅开采煤炭,对煤系共伴生矿产考虑较少或没有考虑,导致资源浪费;近些年国内开始出现煤与共伴生矿产开采的矛盾,煤与共伴生矿产协调开采迫在眉睫。面向煤系全部共伴生战略性金属矿产,聚焦典型代表性的煤系铝土矿和铀矿,保障研究成果的通用性。煤与共伴生矿产协调开采亟需解决的核心共性重大科学问题是:协调开采的固液气应力场、渗流场、化学场、微生物场、采动裂隙场耦合...

The coordinated mining of coal and its co-existed and associated minerals is a major national strategy. China ' s coal measures are associated with 22 kinds of strategic metal minerals such as aluminum, uranium, iron, and gallium. They have many kinds and large resources, overlap with coal seams, and have great differences in occurrences and mining methods. The rock stratum activities and fluid migration of each mineral affect each other' s normal mining operations. Traditional coal mines only focus on coal mining, with little or no considerati...
