黄陵矿区主要含水层特征对煤矿采掘的影响

Influence of main aquifer characteristics on coal mining in Huangling mining area

黄陵矿区位于黄陇侏罗纪煤田北部,主要开采2#煤层,矿井生产中对各含水层特征认识不一,严重影响了煤矿的安全生产。针对此问题,收集整理黄陵矿区历年来的勘查数据,对各地层含水性特征进行客观分析与研究,并对主要含水层的富水性进行详细论述。研究结果表明,影响矿区煤层采掘的主要含水层为白垩系下统洛河组含水层和侏罗系中统直罗组含水层,其中,洛河组含水层对矿井采掘的影响较为突出。洛河组含水层富水性属于弱-中等,弱富水性区域位于矿区的东部,中等富水性区域位于矿区的中西部。今后矿井防治水工作中需高度重视矿区中西部洛河组含水层对煤矿采掘的影响。

Huangling mining area is located in the northern part of Huanglong Jurassic coalfield,mainly mining 2#coal seam.The characteristics of each aquifer are not clear in coal mine production,which seriously affects the safety production of the coal mine.Through collecting and sorting out the exploration data of Huangling mining area over the years,the characteristics of each aquifer are analyzed,and the water yield of the main aquifer is discussed in detail.The results show that the main aquifers affecting coal mining are the lower Cretaceous Luohe formation aquifer and the Middle Jurassic Zhiluo formation aquifer,among which the influence of Luohe formation aquifer on coal mining is more prominent.The aquifer water yield of Luohe formation belongs to weak-medium,the weak water yield area is located in the east of the mining area,and the medium water yield area is located in the middle-west of the mining area.In the future,it is necessary to attach great importance to the influence of Luohe formation aquifer in the middle-west of the mining area on coal mining.
