Since the short of water resources is aggravated increasingly worldwide,it will become an important approach to exploit groundwater in weak aquifer in some special regions,which was ignored in the past.
随着水资源短缺问题的突出和弱含水层采水技术的研发,过去被忽视的弱含水层在缺水地区将成为重要的人畜饮用水水源。
The dewatering calculation in weak aquifer differs from that in rich aquifer,with a far weaker permeability and,while other conditions being the same,with considerably smaller influence radius.
弱含水层的降水设计计算与富水层不同,弱含水层渗透系数远小于富水层,在其他条件相同的情况下,其影响半径也远小于富水层,故在弱含水层降水过程中出现井内动水位与基坑底面静水位相差较大的现象。
Through the analysis of the theoretical principles, the typical cases and the test mining,this paper discusses the mining on the coal face without sand control seam under the poor water content loose aquiclude.
本文从理论分析、典型调查、开采试验等三个方面阐述和验证了在弱松散含水层下实现无防砂保护层的煤层开采不仅具有安全性 ,而且对扩大煤的可采储量、延长矿井服务年限有着重要的意义 。
