摘要: 统一使用勘探、开采过程中获得的水文地质资料,从沉积、富水性规律等方面,对华北煤矿区的主要充水含水层一中奥陶世石灰岩、太原期石灰岩及第四纪松散层作了区域性论述,并对起区域性隔水作用的本溪组进行了详细研究。Abstract: By combining use of data attained during mining operation and field exploration,this paper discussed regionally the regularaties of deposition and water-abundance change of the main coal field charging aquifers in the North China——the mid-Ordovician limestone,Taiyuan group limestone and the Quaternary loose deposit. Studied into detail the Benxi group which acts as an reginal aquitard in the North China.
