| 摘 要： | 李雅庄煤矿是霍州矿区北端的一个井田，目前主要开采2#煤层。基于矿井水文地质条件及开采以来的突水资料分析，认为矿井主要水害为上马家沟组、峰峰组与太原组岩溶裂隙承压含水层，其突水方式是承压水通过导水断层或陷落柱涌人工作面；矿井以F2断层为界，分为东西两部分，西部水位较高，为补给区；东部水位较低，其内的马家沟组、峰峰组与太原组灰岩水基本属于相对独立单元，但三者间存在局部有限导水的特征。据此提出了矿井今后的防治水工作应以查明导水通道（断层、陷落柱），并对其进行注浆加固与封堵为主。

| Abstract: | The Liyazhuang coalmine is situated at the north end of the Huozhou mining area, mainly extracting the No.2 coal seam at present. Based on mine hydrogeological condition and analysis of water bursting data since the mining, considered that the main water disaster of the mine is from the Majiagou Formation, Fengfeng Formation and Taiyuan Formation karst fissure confined aquifers, water bursting mode is the confined water via water conducted fault or subsided column gushing into working faces. Taking the Fz fault as the boundary, the mine can be divided into east and west two parts. The west part has higher water level, the source area; lower water level in the east part, its limestone water in Majiagou, Fengfeng and Taiyuan formations are basically relative independent units, but with local limited conducting features among them in existence. On these grounds, main water control works in the mine henceforth have： to find out water conducting channels （faults, subsided columns） and carry out grouting consolidation and plug-back. |
