摘 要:某铜矿充填采场前期未进行有效滤水,含水充填体渗水对下中段采场生产形成安全威胁。为摸清各中段采场含水充填体的赋水特性,开展了探水孔调查及瞬变电磁探测,提出了不同赋水状态假设,并通过探水验证孔进行验证。针对赋水特性,制定探放水设计方案。结果发现,水主要存在于各中段采场充填体内最下部分段第1~3分层内,上下盘围岩内无水。在各回采联道向上施工放水孔,穿透隔离顶柱和上部中段首采分层假顶至采场充填体内部,疏干采场内赋水。该研究对于同类含水充填体采场赋水特性调查及安全开采具有借鉴意义。The filling stope of a copper mine has not been effectively filtered in the early stage,and the seepage of water-bearing filling body poses a safety threat to the production of the lower and middle stope.In order to find out the water-bearing characteristics of the water-bearing filling body in each middle section of the stope,the water exploration hole survey and transient electromagnetic detection were carried out,and the hypothesis of different water-bearing states was proposed and verified by the water exploration verification hole.According to the water-bearing characteristics,the design scheme of water exploration and drainage is formulated.The results show that water mainly exists in the first to third layers of the lowest section of the filling body in each middle section of the stope,and there is no water in the surrounding rock of the upper and lower plates.The drainage holes are constructed upwards in each mining joint,and the isolated roof column and the first layered false roof in the upper middle section are penetrated to the interior of the stope filling body,so as to drain the water in the stope.This study has reference significance for the investigation of water-bearing characteristics and safe mining of similar water-bearing filling bodies.
