八煤是徐庄矿四层可开采煤层之一，开采八煤遇到的最主要的威胁是下伏太原组灰岩的四灰承压水突出。

Jianghan plain, located in the middle-south of Hubei province. Its ground water resources degree of development and utilization are high. The primary exploitation layers are the upside pore confined aquifer and the underpart cranny and pore confined aquifer. With the rapidly development of urbanization and economic,the water consumption is increasing.That have coused the local ground water table decent.In someplace,the excessive exploitation have induced the groundwater table fall and collapse.

江汉平原位于湖北省中南部，其地下水资源开发利用程度较高，主要开采的为上部[Q_(2+3)]孔隙承压含水层和下部[Q_1+N]裂隙孔隙承压含水层中的水，随着区内城市化建设和经济的迅速发展，用水量增加，区域地下水位已有一定幅度的下降，局部地区因过量开采已形成地下水降落漏斗和地面塌陷等现象。
