Research on Hydrolytic Weakening Properties of Bad rock in Jiu dingshan Cu-mo Mine
Roadway deformation,support destruction and large area collapse of wallrock caused serious influence on production in Jiu dingshan Cu-mo Mine.Based on test and research on the types and contents of clay minerals contained in ore rock and their crumbling and softening properties,this paper analyzed the degree and ways of stope drift wallrock deformation affected by vvatcr.found out the major cause for roadway destruction/This offers important reference value for choice of roadway supporting method and comprehensive control of roadway destruction in Jiu dingshan Cu-mo Mine.
