奥陶系含水层由于范围广、富水性较强，长期以来一直是煤矿生产的重要地层。以山西临县庞庞塔井田为例，本区奥灰含水层富水性中等，奥灰水位普遍高于主要可采煤层底板标高，底板突水已成为矿井水害防治的重点。因此，从大气降水、地表水、地下水和老空水等充水水源，以及断层、陷落柱和顶底板采动破坏等方面分析了矿井充水条件，这对煤层开压、开采具有比较重要的指导意义。

The Ordovician aquifer due to a wide range of water rich, strong, has long been important to the formation of the coal mine production. Shanxi Lin County Pangpangta mine as an example, the Ordovician limestone aquifer water medium, Ordovician limestone water level is generally higher than that of main mineable coal seam floor water inrush from floor level, has become the focus of prevention and control of mine water disaster. Therefore, from the atmospheric precipitation, surface water, groundwater and other water filling goaf water source, and the fault, karst collapse column and roof and floor mining failure are analyzed from the aspects of mine water filling condition, the guiding significance to coal seam mining with pressure, the more important.
