本文依据方兴煤矿勘探资料，从区域水文地质条件、地层富水性、矿井充水因素等方面分析矿区水文地质特征分析，结论表明，矿区第四系，夜郎组九级滩段、沙堡湾段，龙潭组地层富水性弱，第四系属弱含水层、其余为相对隔水层；长兴组地层富水性中等，属中等含水层；茅草铺组、夜郎组玉龙山段地层富水性强，属强含水层；茅口组地层富水性极强，属强含水层。矿井充水水源主要有大气降水、地表河流、地下基岩裂隙水及岩溶水，充水通道主要有岩石节理裂隙、采矿冒裂隙、断层破碎带、构造裂隙、老窑采空区、岩溶管道等。划分矿区9、11号煤层水文地质条件复杂程度中等，水文地质类型属三类二型；13、14号煤层水文地质条件复杂，水文地质类型属三类三型。

Based on the exploration data of Fangxing Mine, this paper analyzed the hydrogeological characteristics of the mining area from the aspects of regional hydrogeological conditions, stratum water abundance, and mine water filling factors. The conclusion showed that the Quaternary system of the mining area, the ninth-level beach section of the Yelang Formation, the Shabaowan section, and the Longtan Formation had weak water abundance. The Quaternary system belonged to the weak aquifer, and the rest was the relative aquiclude. The water abundance of the Changxing Formation was medium, which belonged to medium aquifer. The Yulongshan section of the Maocaopu Formation and the Yelang Formation was rich in water and belonged to a strong aquifer ; the Maokou Formation was extremely rich in water and belonged to a strong aquifer. The water filling sources of the mine mainly included atmospheric precipitation, surface rivers, underground bedrock fissure water and karst water. The water filling channels mainly included rock joint fissures, mining fissure, fault fracture zone, structural fissure, old kiln goaf, karst pipeline and so on. The hydrogeological conditions of No.9 and No.11 coal seams in the mining area were medium in complexity, and the hydrogeological types belonged to two model of three category; the hydrogeological conditions of No.13 and No.14 coal seams were complex, and the hydrogeological types belong to three model of three category.
