摘　　要：宝鼎矿区浅部资源行将枯竭,深部开采已迫在眉睫,而预测深部涌水量成为其首要解决的问题。通过对矿区深部水文地质条件研究与矿井充水因素的分析,认为矿区各含水间水力联系差,同一含水层组的不同地段间的含水裂隙的连通性亦差;断层多为高角度压性逆断层,导水性差,富水性弱;矿区上部水平及下部水平的浅埋区的充水水源主要为大气降水和老窑水,而下部水平主要的充水水源为上覆水平的采空区积水和地下水。运用比拟法和地下水动力学对延深的第一接替水平四个区段的较大涌水量和一般涌水量进行了计算,经过比较,采用了比拟法的计算结果:矿井的一般涌水量为2860.88m3/d,据此提出了切实可行防治水措施,从而为矿井深部建设提供了水文地质依据。The coal resources in the shallow part Baoding mine area about to exhausted,thus the deep part mining is extremely urgent,while the prediction of deep part water inflow is the first issue to be solved.Through mine area hydrogeological condition study and mine water filling factor analysis,considered that the hydraulic connection between aquifers are rather poor,connectivity of water-bearing fractures in different sectors of a same aquifer（group） is also poor.Faults in the area are mostly high angle compressive reverse faults with poor transmissibility and water yield property.Water filling sources of mine area upper levels and shallow part of lower levels are mainly atmospheric precipitation and gob area water,while main water filling sources of lower levels are gob area water from overlying levels and groundwater.Using analogue method and groundwater dynamics carry out computation for greater and general mine inflows in four sectors of deepening first relayed level.After comparison,results from analogue method are adopted： general mine inflow is 2860.88m3/d.For reason given above,practical water control measures are put forward thus provided hydrogeological basis for deep part mine construction.
