| 摘 要： | 随着矿井开采深度的增加,一些深部有高承压水的煤矿正面临高承压水上采煤的现状。根据"下三带"理论,在工作面推进过程中,煤矿底板要受到采动压力及高承压水的破坏,但是底板破坏带及承压水导高带很难用解析的方法进行计算。基于此,通过研究地下水渗流场和应力场耦合作用机理,建立了渗流场和应力场的耦合方程,并采用数值计算软件ANSYS对葛亭煤矿11601工作面进行了模拟研究,获得了采动破坏带和承压水导升带的破坏范围。最后,用双端堵水器测定底板破坏深度验证了模拟的结果。

| Abstract: | With mining depth increasing,some mines have to mine coal above high pressurized water in deep.According to "lower 3 zones" theory,floor of mining face suffer mining pressure and high water pressure during mining advance.But it's very difficult to calculate the floor damage and water-conductive height with analytic method.Based on this,this paper researched coupling mechanism of seepage field and stress field and set up stress-fluid coupling equation.Then this paper applied ANSYS to simulating 11601 Mining ... |
