摘要
针对小东沟矿区内各废弃矿井及巷道报废时间较长、老窑及采空区均有不同程度积水,以及存在烧变岩积水的问题,开展含水层特征及防治水分析。利用MAPGIS强大的数据存储、空间数据处理和分析等功能输出成果图,评价研究区充水含水层富水性强弱,提出在矿井正常开采中应加强对老空积水的防治,且留足防水煤柱。初步分析B_(6)号煤层涌(突)水危险区主要分布在以往开采工作面区域,未来开采工作面掘进到首采区以后区域,大部分区域为涌(突)水危险区和较危险区,建议遇到积水量大的开采工作面、深部老窑采空区及废弃巷道底部时采取必要的防治水措施。
In light of long deserted time of mined-out mines and their roadways,different level of accumulative water in goaf,and existing burnt-rock water in Xiaodonggou mining area,the aquifer characteristics and water control and prevention are analyzed.This paper makes use of the powerful functions of MAPGIS,such as data storage,spatial data processing and analysis to output the result map and assess the water enrichment of the aquifer in the study area.It is proposed that the prevention and control of accumulated water in old goaf should be strengthened in normal mining,and enough water-prevention coal pillars should be retained.Initial analysis shows that the water inrush danger zones of B6 coal seam are mainly distributed in the past working face area,and after the future mining face advancing to the initial mining face area,most part of the area is water inrush danger zone.We suggest that the necessary water prevention and control measures should be taken on the mining face when encountering the largest accumulated water,the deep old goaf and the bottom of abandoned roadway.
