胶东半岛矿产资源丰富,开采过程中井下涌出的大量地下水造成了水资源的严重流失,出现地面下降等不良后果。为了克服井下涌水造成的破坏性影响,提出用ASR法在金属矿区进行回灌。以试验矿区为例,对回灌技术原理进行分析,在此基础上,设计了试验方案,利用管井进行3组回灌试验。试验现象表明,胶东半岛金属矿区进行地下水回灌具有可行性。
The Jiaodong Peninsula is rich in mineral resources. The large amount of groundwater poured from the underground during the mining process has resulted in serious loss of water resources and adverse consequences such as ground drop. In order to overcome the destructive impact caused by underground water inflow, proposed ASR method in the metal mining area for recharge. Taking the pilot mining area as an example, the principle of the recharge technology is analyzed. Based on this, a test plan is designed and three sets of recharge tests are conducted by using the tube well. The experimental results show that it is feasible to recharge groundwater in the metal mining area of Jiaodong Peninsula.
