居隆庵菱形断块是相山地区重要铀资源基地,21号带地处居隆庵菱形断块的西部,水文地质条件属简单中等类型,相对其它矿床更为复杂.笔者采用狭长水平坑道法和水文地质比拟法对该矿床进行矿坑涌水量估算,其钻孔单位涌水量＜0.1 L·(s－1·m－1),预测矿坑涌水量＜29 m3·h－1.研究显示,矿床主要含水带(构造及裂隙)富水性弱且不均,导通性不强；而地下水补给条件好,水压高.在矿床开采过程中应加强监测,及时判断可能出现的涌水量变化情况,保证生产安全.

Julong’an rhombus block is an important uranium resources base and the zone 21 is located in west of the block,and its hydrogeology is of simple middle type compared to the more complicated other ares.Narrow tunnel method and hydrogeologic analogy method was used for mine water inflow esti-mation,the drilling unit water inflow is lower than 0.1 L·s-1 ·m-1 ,and the perdiction of mine water inflow is less than 29m3 ·h-1 ,the main aquifer water of the deposit (structure fissure aquifer)is of weak and uneven capability,and conduction performance is not strong;but the groundwater is of good recharge condition and high water pressure.Monitorring should be strengthen in the mining process,so as to make in time judge of water inflow changes and to ensure the mining production.
