摘　　要：煤矿层下方的铝土矿,开采时遇到的水文地质问题尤为复杂。以豫西偃龙矿区焦村-府店矿段铝土矿为例,结合水文地质单元、矿体与含水层关系和矿区地下水补径排等因素,从充水水源和充水通道两方面分析该煤下铝矿区矿床充水因素,结果可知:矿床充水水源有地下水、老窑水、地表水体和大气降水,充水通道主要有渗入性通道、溃入通道和人为充水通道三种。矿床顶底板都是直接充水含水层,且富水性分布不均,因多条断裂构造的切割,各含水层及充水水源有可能产生联系,从而使矿床充水因素更加复杂。通过全面分析矿区水文地质条件及矿床充水因素,对煤下铝水害防治具有重要意义。Layer at the bottom of the bauxite in coal mine,the hydrogeological problems encountered in the process of mining is particularly complex in the western suppress a dragon jiao village-house shop ore block bauxite mining area as an example,the combination relations orebody and aquifer hydrogeological units and mining factors such as diameter and discharge of groundwater,from two aspects of water filling water and water filling channel analysis the aluminum under the coal mine water filling factors of ore deposits,the result shows that water filling source of ore deposits are groundwater water of old kiln and atmospheric precipitation,the surface water filling water channels are mainly into sexual crush channel and artificial water filling three channels. Through a comprehensive analysis of the hydrogeological conditions of the mining area and the water-filling factors of the deposit,it is of great significance for the prevention and control of water disasters caused by coal and aluminum under coal. The results show that the water-filling sources of the deposit are ground water from the old kiln water and atmospheric precipitation,and the water-filling channels mainly consist of infiltration channels and artificial water-filling channels.
