岱庄井田第四系沉积环境与其含水层富水性浅谈

Discussion on dispositional environment and water yield property of aquifer of the Quaternary in Daizhuang coalfield

岱庄井田第四系含水层特征影响到矿井涌水量的预测,在统计分析钻孔资料及抽水试验资料基础上,对该井田的第四系沉积环境和富水性特征进行了分析,认为第四系河流相含水层为强富水性且渗透性强,湖泊相含水层为弱富水性且渗透性弱。

The characteristics of the Quaternary aquifer in Daizhuang coalfield affect the prediction of water yield of mine.Based on statistical analysis of drilling data and pumping test data,this paper analyzes the despositional environment and water yield property characteristics of the Quaternary in the coalfield,and concludes that the river facies aquifer of the Quaternary is of strong water yield property and strong permeability,the lacustrine facies aquifer has weak water yield property and weak permeability.
