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 fragie and the shallow sean closed to the lose stratum would ofren met with the dangers of the water inrush and sand inush disaster during the mining period. with several years stucy and development.great chievements were obtained from the basic study.engineeing practices and other areas. The present water inrush and sand inrush studly stuity was focused on the three aspects of the mechanism,prediction and prevention.The study on the water inrush and sand inuish mechanism was conduced with the estabishmen of the sand paricle mechanics stoucture model.esthydrodyoanics and oter methods .The predicton of the water inrush and sand inrush was conducted with the ge ological o dition comparison,ydraulic gradient judgement,mult factors comprehensive nl ysis and other methods The prevention and controlof the water inrsh and sand inrsh would be conducted to reduce the underground water table before the mining operation conducted a a key and diferent engineering measures would be appied to reduce the risks of the water inrush and sand inrushBased on the sunmaizing the relevant research resuits taking the water preserved nining as the mission,.the paper pointed out the orientaton of the waterinrush andsand inrush study.
