地下铝土矿采矿环境再造连续采矿理念

Concept of the mining environment reconstructing continuous mining in underground bauxite

为解决复杂难采、水害突出的铝土矿地下开采技术难题,基于采矿环境再造和连续采矿理论,提出了地下铝土矿采矿环境再造连续采矿理念.新理念主要包括基于疏、导、引、堵和用等综合水处理措施的开采水环境再造技术、借鉴金属矿无间柱连续采矿技术和煤炭机械化采煤技术的连续采矿技术、以矿岩地应力人为控制方式实现的应力环境再造技术等三项主要内容.新理念为复杂难采、水害突出、低价值软破及原本不具备开采价值等矿体的开发利用提供了一条新思路.

For solving the mining technical problem in underground bauxites belong to the complex and hard-to-mine mineral deposits with the outstanding water disaster,the concept of the mining environment xeconstructing continuous mining in underground bauxite were proposed on basis of the theories of mining environment reconstructing and continuous mining. Mining water environment reconstructing based on comprehensive water treatment measures of draining,guiding ,citing,plugging, using and etc. , mechanized continuous mining technology with reference to non-pillar continuous mining technology of metal mines ＆ coal mines and stress environment reconstructing achieved by means of arti^icially controlling rock mass stress are main contents of the new concept. The concept provides a new development thought for exploiting the ore body of low-value soften and broken,complex and hard-to-mine ,prominently water disaster ,and without original mining value.
