为了进一步查明平禹一矿寒武系灰岩的富水性及连通性,正确评价寒灰岩溶水疏放难易程度,利用三采区17个寒灰放水孔,技改井车场附近25个放水孔,对寒灰含水层进行了三个落程的群孔放水试验.从结果可以看出,寒武系灰岩含水层富水性强,连通性好;技改井对今后矿区排水起着重要的作用;各个观测孔在历时相当长时间后水位并没有达到稳定的状态,而是表现为水位降幅减小,表明寒武系灰岩水是可以疏放的.矿井排水依然为今后主要的防治水方法.

In order to take further research on the water productivity and connectivity of the Cambrian limestone and evaluate the feasibility of the dewatering exactly of the Cambrian limestone karst water in the 1st mine of Pingyu,17 outlet holes of the 3rd mining area and 25 outlet holes of rehabilitated well yard were used to carry out of the three falls dewatering test of group holes.The result indicated that the water productivity and connectivity of Cambrian limestone aquifer is good,the rehabilitated well yard has significance on future dewatering.And the water level decreasing amplitudes of all observation wells were diminished instead of coming to steady state demonstrated the dewatering of Cambrian limestone karst water is feasible.The dewatering will still be the main method to prevent mine water disasters.
