Abstract：To achieve the aim that coal mining under water-preserving is the development trend and requirement of ecological environment in coal mine area,and systematically summarizing achievements in the technology of coal mining under water-preserving and further promoting its development,the theory of coal mining under water-preserving and research status of mining technology were summarized comprehensively using the method of comprehensive analysis,based on overviews the recent achievement and the latest development of coal mining under water-preserving.In addition,the development trend in this field was pointed out.The study results showed that the focus on achieving the goal of coal mining under water-preserving was selection of reasonable mining upper limit and the appropriate mining methods to control ecological water level based on specific hydro-geological conditions.The further study trend is to improve the prediction accuracy of development height of the fractured water-conducted zone by researching on spatial combination characteristics of overlying strata in main mining coal seam and conforming combination form of groundwater,coal,rock and so on in three dimensional spaces.
