摘　　要：为提高地面钻井瓦斯抽采效率,采用数值模拟研究方法分析了淮南潘三矿1792(1)保护层工作面开采过程中覆岩的水平和垂直运动规律、剪应力变化规律及它们对地面钻井的破坏机理,提出了有效的改进措施,对地面钻井的设计及布置具有重要的指导意义。In order to improve the gas extraction efficiency of surface well drilling,this paper analyzes the horizontal and vertical movement laws and the change laws of shear stress of the overlying rocks at 1792（1） protective working face of Huainan Pansan Mine,and the destruction mechanism which has an effect on surface well drilling,it also puts forward many effective measures for improvement,which has an important guiding significance on the design and layout of surface well drilling.
