摘    要：采用数值模拟方法,以康家湾铅锌矿1号矿体采后充填为模拟对象,分析了盘区矿柱留设与否、胶结充填体力学性质2个因素对顶板围岩中导水裂缝发育情况的影响,得出了有益于指导现场生产的重要结论,同时,也为进行导水裂缝扩展高度的预测提供了一种新的方法。

Abstract: Aimed at the extraction of No. 1 ore body at Kangjiawan Zinc-Lead Mine with two-stepback-filling method,the effect of pannel barrier(arranged or not)and mechanical propertiesof cemented filling body on the development of water-conducting fissure in overlying rockwas analyzed by means of numerical simulation. Some important conclusions are of great sig-nificance to the mine production, and a new method used to predict the maximum developingheight of water-conducting fissure has been provided.
