山东省平邑县归来庄金矿床充水因素分析及水害治理方向
|
摘要
归来庄金矿床为鲁西南地区唯一特大型金矿床,矿山已经转为地下开采,目前矿山正常涌水量为98491m~3/d,矿坑共发生中大型突水56次,其中最大突水点水量高达2000m~3/h,矿山涌水量大,突水频繁,矿坑涌(突)水对矿山深部开采生产安全构成了严重的威胁。该文通过收集以往矿床勘查、核实水文地质资料、地下水连同试验成果、矿山水文地质监测资料并经现场调查,认为该矿山充水来源主要有三个方面:大气降水,地表水(浚河水)和碳酸盐岩裂隙岩溶水,其中碳酸盐岩裂隙岩溶水对矿床直接充水,大气降水和浚河水通过碳酸盐岩含水岩组的导水通道间接补给矿坑。矿山水害治理重点在奥陶系碳酸盐岩类含水岩组的岩溶、构造导水通道,提出了对浚河河床漏水点进行注浆封堵和地下水帷幕注浆截流治水方案。
Guilaizhuang gold deposit is the only super large gold deposit in southwest Shandong province. The mine has been converted to underground mining. At present, the normal water inflow of the mine is 98491 m~3/d. There are 56 times of water gushing(inrush) in the mine. Among them, the largest water inflow point is up to 2000 m~3/h. The mine has a large amount of water gushing(inrush) frequently. It has a serious threaten to the safety of deep mining production. Through collecting hydrogeological data in the past exploration, groundwater and test results, hydrogeological monitoring data, field investigation and research, It is considered that main sources of water filling in the mine are atmospheric precipitation, surface water(dredged River water) and carbonate fissure karst water. Among them, carbonate fissure karst water fills the deposit directly, meteoric water and dredged river water indirectly recharge ore pits through water channel. Mine water hazard control focus on karst and tectonic channels of Carbonate aquifer formation. A scheme of grouting and plugging for the water leakage point of Juhe river bed and groundwater grouting closure have been put forward.
