Investigation on Water-bearing Characteristics of Stope Filling Body Under the Condition of No Filter Well
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 sec-tion 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 isolat-ed 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 investiga-tion of water-bearing characteristics and safe mining of similar water-bearing filling bodies.
