摘　　要：根据平煤八矿己组煤底部的L2灰岩含水层、L7灰岩含水层和寒武灰岩含水层的地质和水文钻孔资料,通过分析己组煤底板含水层的水位标高及己组煤与含水层的距离,利用突水系数法对L2和L7薄层灰岩含水层以及寒武厚层灰岩含水层的突水危险性进行评价和突水危险性分区,结合断层的发育情况设计底板灰岩水的防治水方案,制定了己组煤底板含水层的疏水降压、岩层井下注浆加固和井下强排水的防治水方案,为矿井己组煤安全生产奠定了基础。According to the geological and hydrological borehole information of L2 limestone aquifer,L7 limestone aquifer and Cambrian limestone aquifer under the No.6 seam floor in No.8 Mine of Pingdingshan Coal Mining Group,with the analysis on the water table level of the aquifer under No.6 seam floor and the distance between the seam to the aquifer,the water inrush coefficient method was applied to the evaluation on the dangers of the aquifers in L2 and L7 thin limestone as well as in the Cambrian thick limestone and to the dangers divided.In combination with the fault development conditions,the water prevention and control plan of the limestone water under the seam floor was designed.Water prevention and control plan with water bumping and water pressure dropping of the aquifer under seam floor,underground strata grouting reinforcement and underground water drainage was set up to set the basis for the mine safety production.
