【摘要】 西部煤矿区生态环境脆弱,地下潜水位低,地表被第四系松散沉积层覆盖,土质疏松,以风积沙为主,非饱和带和饱和带介电常数有明显差异。在分析研究区工程地质、水文地质条件的基础上,采用探地雷达对神东矿区补连塔32201工作面进行了野外实地探测,通过对比分析处理后雷达剖面图与该地区钻孔资料,验证了用探地雷达探测干旱半干旱地区地下潜水位的可行性。更多还原

【Abstract】 The ecologic environment is fragile and groundwater table is low in Western Coal Mining Areas,its surface is covered by the 4th loose sediments,loose soil and aeolian sand are the majority,there are distinct differences in permittivity between nonsaturated zones and saturated zones.Based on the analysis and research of engineering geology and hydrogeologic conditions,this paper shows the field detection of the Bulianta 32201 working face of Shendong Mining Area by using GPR.After the contrastive analysis of processed GPR section plane and borehole datum,it further proves the feasibility of detecting groundwater table in arid and semiarid region by GRP.更多还原
