| 摘 要： | 采空区地面沉陷损毁地表耕地是地下开采矿山引发的主要地质环境问题之一,通过对佛子冲铅锌矿104号矿体的工程地质条件、采场结构参数及原岩应力场进行调研,并在此基础上运用FLAC~(3D)建立采空区数学模型,对佛子冲铅锌矿104号矿体采空后采空区地压力分布、岩体变形移动等进行模拟与研究,预测采空区地面沉陷损毁地表耕地的程度,并根据矿山的实际情况提出防治措施,为保护矿山采空区沉陷区内的耕地提供依据和参考。

| Abstract: | Damaged cultivated land caused by ground subsidence in mined-out area is one of the major geological environment problems resulted from underground mining.Based on the survey of orebody No.104 in Fozichong Pb-Zn deposit in terms of its engineering geological conditions,stope structure parameters and in-situ rock stress field,and through building a mathematical model of the mined-out area by applying FLAC3D ,this paper conducted simulation study on the formation pressure distribution and rock mass deformation and mobility in the mined-out area after mining out of orebody No.104 in Fozichong Pb-Zn deposit.This paper also predicted the extent to which the ground subsidence would damage the cultivated land,and put forward controlling measures according to the realities of the mine which could be used as basis and reference for future protection works of the cultivated land at subsidence in mined-out area of the mine. |
