Influence of coal mining on water resources of surrounding reservoirs in a scattered area——Take Xingfu Reservoir as example
In order to promote the integration of scattered coal resources in an orderly way,effectively alleviate the contradic-tion between supply and demand of coal,and promote the economical and intensive use of coal resources,there are many problems in actual work,such as the impact of mining on the surrounding water resources.Based on the scientific investiga-tion and evaluation of the impact of mining activities on geological structure,surface runoff,groundwater system and water supply river in the area from Changchong to Yiluzhai in Qingshan town of Pu'an County,we discuss whether coal mining would affect the dam safety of Xingfu reservoir in the town,and whether it would cause leakage of reservoir and have an in-fluence on the production and life of coal mine(including mine water inrush),etc.In this paper,the related parameters of strata,coal seam,hydrological engineering and so on are taken from adjacent normal production mines and the reliability of them is high,thus our study is of great theoretical and practical significance to ensure the safety of the reservoir and investi-gate the influence of scattered coal resources exploitation on reservoir water resources.
