However the underground water lowering which takes place in the water bearing layer in chief has the inevitable influence on the surface subsidence .

矿区地下水位降低的主要原因为承压 水通过采动裂隙向下渗流、煤层开采前顶板岩溶 含 水 岩 层的疏干以及地面人为钻井取水。

But the above method can not be used in water / oil bearing beds or water layer which have been injected .

但 含油 水层或 水层投注后不能用上述方法 确定动态残余油饱和度。

For the purpose of safe operation the soft foundation shall be improved using the follow methods : specify loading and water filling rate according to engineering characteristics of bearing compression layer of the foundation ;

为保证软地基土油罐的安全使用，需要对软基础合理处理，即根据地基 持 力压缩 层的工程特性决定加荷充 水速率的大小；

The Study of Hydrogeological Test for Poor Water Bearing Layer

弱 含 水层水文地质试验研究

The functions of clay layer under Quaternary in under-water mining is studied and when thickness of clay layer is larger than 3m work face water inrush quantity is very little from upper water bearing layer .

研究了第四系底部黏土层在水体下采煤中的作用，认识到当底黏厚度大于3m时，上部 含 水层对工作面充水量很小。
