摘要
我国西部煤矿区生态环境脆弱,近松散层浅埋煤层开采时常会遇到突水溃沙灾害的威胁,经过多年研究和发展,在基础研究、工程实践等领域取得了大量成果。就目前的研究而言,突水溃沙研究集中在机理、预测、防治等3个方面,突水溃沙机理的研究主要采取建立沙粒力学结构模型、试验及水动力学等方法;突水溃沙预测主要采用地质条件对比、水力坡度判断及多因素综合分析等方法;突水溃沙的防治以降低采前地下水位为核心,采取不同的工程措施以减轻突水溃沙风险。在在总结相关研究成果的基础上,以保水采煤为宗旨,指出了突水溃沙领域研究的方向。
The ecologic environment of west China coal mining area was fragile and the shallow seam closed to the loose stratum would often meet with the dangers of the water inrush and sand inrush disaster during the mining period. With several years study and development,great achievements were obtained from the basic study,engineering practices and other areas. The present water inrush and sand inrush study study was focused on the three aspects of the mechanism,prediction and prevention. The study on the water inrush and sand inrush mechanism was conducted with the establishment of the sand particle mechanics structure model,test,hydrodynamics and other methods. The prediction of the water inrush and sand inrush was conducted with the geological condition comparison,hydraulic gradient judgement,multi factors comprehensive analysis and other methods. The prevention and control of the water inrush and sand inrush would be conducted to reduce the underground water table before the mining operation conducted as a key and different engineering measures would be applied to reduce the risks of the water inrush and sand inrush. Based on the summarizing the relevant research results,taking the water- preserved mining as the mission,the paper pointed out the orientation of the water inrush and sand inrush study.
