【摘要】 在银波铅锌矿现状分析的基础上,根据矿区地质条件,进行了岩体工程稳定性分析,结果表明:(1)工程地质条件中等,岩体的失稳形式主要表现为岩体顺片理面滑落;(2)矿区巷道破坏形式主要有两种:一种是破碎带型破坏;第二种为片帮型破坏;巷道破坏主要表现为沿节理面或层理面的片帮和掉块,沿节理裂隙等弱面出现滑移;(3)总体上该矿山的岩体是稳固的;得到的结果能够为进一步的采矿设计提供理论基础。更多还原

【Abstract】 Based on the analysis for the present situation of Yin-bo lead-zinc mine, the stability analysis is done for the rock mass according to the geology situation of mining area, the analysis results show that, (1) engineering geological conditions is in the middle class. The failure modes of rock mass mainly exhibit in the form of slipping along joint plane; (2) failure modes of mine tunnel contain two type, fault failure and rall falling failure; the failure of tunnel mainly contains slipping along the joint plane, or the weakness plane with crannies; (3) the general stability of rock mass in the mine is stable; The analysis results can give further theoretical guidance for the mining design.更多还原
