摘要
我国能源禀赋特点决定了煤炭主体能源地位短期难以改变,其中,西部煤炭资源担负着我国基础能源自主供给的核心角色。但西部煤炭多处于干旱-半干旱带沙漠-黄土覆盖生态脆弱区,易因开采扰动引起地下水及生态环境产生显著影响。因此,减损开采成为西部生态脆弱区煤炭资源安全高效开发与环境保护协调发展的必然选择。立足西部煤炭资源开发现实情况,提出了西部生态脆弱区煤炭减损开采面临的四大关键科学问题,即:①煤-水空间发育组合特征;②采动过程地质条件变化规律;③保水开采分区及地质判据;④西部煤炭减损开采技术体系构建思路。同时,详细阐述了煤炭减损开采技术发展状况及存在的现实难题。在此基础上,尝试构建西部生态脆弱区煤炭减损开采技术体系,并展望了西部煤炭减损开采技术未来发展方向。相关研究以期为西部生态脆弱区煤炭绿色减损开采提供借鉴。
The endowment characteristics of China’s energy source determine that the status of coal as the main energy source is difficult to change in the short term.To be sure,coal resources in Western China are playing the core role of independent supply of basic energy.However,the western coal is mostly located in the desert-loess covered ecologically fragile area which is arid and semi-arid area.The area is susceptible to the disturbance of mining which causes the destruction of groundwater and ecological environment.Therefore,achieving the coordinated development of safe and efficient coal mining and ecological environment protection has become an inevitable choice for the exploitation of coal resources in the ecologically fragile areas of Western China.Based on the actual situation of coal resources development in Western China,four scientific issues were proposed to realize coal green mining in ecologically fragile mining areas of Western China:①clarifying the characteristics of coal-water spatial growth combination is;②mastering the change rule of geological conditions during mining process;③realizing the zoning of water conservation mining and the discrimination of geological basis;④building technology system of coal detraction mining in Western China,and elaborating its development status and key problems.The development concept of coal green-detraction mining in ecologically fragile areas of Western China was put forward.The challenges of the future development of mining technology were sorted out.Relevant research is expected to provide a certain reference value for coal green mining in ecologically fragile areas of Western China.
