| 为研究红林煤矿茅口组地下水对开采15号煤层的影响，在综合分析实际采掘资料及物探、水文地质钻探资料的基础上，研究了红林煤矿区地质构造、煤系地层下部茅口组岩溶水文地质特征。研究结果表明:以F1断层带为界，区内分为北西和南东两个独立的含水层子系统，断层北西盘茅口组水位高于15号煤层底板标高65 m以上，南东盘则低于15号煤层底板标高，并且茅口组岩溶地下水水位总体具有随埋深增加而变深、补给条件及富水性逐渐减弱的趋势。在其基础上，对矿山未来开采15号煤层时底板的突水危险性进行了分区。 |

| In order to study the influence of the groundwater in the Maokou formation of Honglin coal mine on the exploitation of No15 coal seam，in this article，it studies the geological structure of the Honglin coal mine area and the hydrogeological characteristics of karst in the lower part of the coal-bearing strata of the Maokou formation on the basis of comprehensive analysis of the actual mining data and geophysical and hydrogeological drilling dataThe research results show that:with the F1 fault zone as the boundary，the area is divided into two independent aquifer subsystems in the northwest and southeast，the water level of the Maokou formation in the northwest block of the fault is more than 65m higher than the elevation of the bottom plate of No15 coal seam，and the southeast block is lower than the elevation of the bottom plate of No15 coal seam，and the water level of karst groundwater in the Maokou formation generally has the trend of deepening with the increase of burial depth，and the recharge conditions and the water-richness gradually weakenOn the basis，the outburst water risk zones of the bottom plate in the future exploitation of No15 coal seam in the mine is zoned |
