多年冻土区蕴藏着丰富的矿产资源,矿业开发已成为多年冻土区经济发展的主要产业之一.但是,在其开采过程将不可避免地受到冻土的影响,也造成多年冻土区生态环境恶化的影响.在西部大开发的进程中,能源需求量逐渐增加,而多年冻土区矿山露天开采量逐渐减少,开展多年冻土区矿山地下开采相关的研究工作显得尤为迫切.在分析和总结前人研究成果的基础上,综述了近年来国内外有关多年冻土区矿山开采问题的研究现状,并详细介绍了多年冻土区矿山开采过程中围岩热力学性质的变化规律及其施工技术以及冻土环境保护的定性定量评价,最后概述了多年冻土区类似工程的研究方法的借鉴性,并在此基础上提出了今后的研究方向.
The permafrost region is rich in mineral resources, mining development has become one of the major industries in the economic development of permafrost regions.But the mining process will inevitably be affected by the frozen soil, also caused the permafrost ecological The impact of environmental deterioration in the development of the western region in the process of energy demand increased gradually, while the permafrost mines gradually reduce the amount of open-pit mining in the permafrost mining underground mining related research work is particularly urgent.In the analysis and On the basis of summarizing the research results of the predecessors, the research status quo of mining in permafrost regions both at home and abroad in recent years are reviewed, and the changing rules of the thermodynamic properties of surrounding rock in the permafrost region and the construction techniques are introduced in detail As well as qualitative and quantitative evaluation of the permafrost environmental protection. At last, it summarizes the reference of the research methods of similar projects in the permafrost region, and puts forward the research direction in the future.
