摘　　要：科学分析煤矿矿井水文地质特性是矿井水文地质类型划分和防治水方案制定的前提。通过对车家庄煤矿地质勘探资料、采掘揭露地质资料、地面水文观测孔水位观测资料和矿井涌水量观测资料的分析,结合矿井近5 a(2021—2025年)的采掘规划,采用煤层开采“上三带”(垮落带、导水裂缝带和弯曲下沉带)理论、突水系数理论,计算了13煤层开采顶板导水裂缝带发育的最大高度、底板奥灰含水层的最大突水系数,预计了近5 a矿井涌水量,确定矿井水文地质类型为中等;并结合矿井现有排水设施,提出了相应的防治水工作建议。Scientific analysis of the hydrogeological characteristics of coal mines is the prerequisite for the classification of mine hydrogeological types and the formulation of water prevention and control plans.Through the analysis of the geological exploration data,excavation and exposure geological data in mining engineering,water level observation data of surface hydrological observation holes and water inflow observation data under the shaft in Chejiazhuang Coal Mine,combined with the mining plan of the mine for in recent five years(2021-2025),the“Three Zones”(caving zone,water flowing fractured zone and curve subsidence zone)Theory and the Water Bursting Coefficient Theory were used to calculate the maximum height of water-conductive fissure zone in roof and the maximum water bursting coefficient of Ordovician limestone aquifer in floor of 13 coal seam;and the water inflow in recent five years was estimated,hydrogeological type of the mine was determined as medium.Combined with the existing drainage facilities in the mine,the corresponding suggestions for water prevention and control were put forward.
