郑州矿区采动底板构造控水及其防治研究

Study on Tectonic Control Floor Water and its Prevention Water-inrush by Mining Floor in Zhengzhou Mining Area

在对郑州矿区大量相关资料综合分析的基础上,对郑州矿区采动底板构造控水进行分析。提出了底板直接充水含水层充水、太原组静储含水层复合水源充水及沟通奥灰含水层充水3种底板突水的水源类型,并结合构造因素对采动底板的岩层组合特征及其导水通道进行分析,得出了构造在底板采动突水中起关键作用。最后结合构造层位分析对该矿区底板水的防治提出了合理的注浆加固层位,这为郑州矿区煤炭资源向深部开采所引起的底板水防治提供了部分参考的依据。

The condition of tectonic control floor water is analyzed by compositive analysis the abundant data of Zhengzhou mining area.The three water source types are presented,and rock strata combination characteristics and water conducting are analyzed to mining floor by structure contral factors,the key function of structure is drawn on water-inrush from floor.Finally the reasonable grouting reinforcement strata are put forward combining tectonic strata,and it is as the basis for prevention and cure of floor water for the mining coal to the depth of the west of Zhengzhou mining area.
