摘要
根据和静县诺尔湖铁矿地下水类型、含水岩组等区域水文地质特征,研究构造破碎带和地表水对铁矿安全开采的影响,结果表明:研究区地下水类型主要包括现代洪积砂砾层中的孔隙潜水、坡积碎石层中的孔隙潜水、冰碛砾石层中的孔隙潜水、基岩风化带裂隙网状水以及基岩裂隙脉状水等五种类型;区内地下水的补给来源主要是大气降水和冰雪融水,通过季节性溪流和渗入基岩风化裂隙两种方式径流和排泄;基岩破碎带和裂隙发育带的存在,为基岩充水提供了有利空间。
This study deals with the influence of structural fracture zone and surface water upon mining safety based on underground water type and aquifer group indicates.The results indicate that underground water in the studied may be divided into5types such as pore water in the modern diluvial gravel layer,pore water in diluvial gravel layer,pore water in moraine gravel layer,mesh fissure water in bedrock weathering zone and bedrock fissure vein water.The groundwater recharge is originated from atmospheric precipitation and snow melt water.The existence of the bedrock fracture zone and fracture zone provides a favorable space for bedrock water filling.
