摘　　要：由于缓倾斜中厚矿体的倾角较小,且中间存在薄弱夹层,开采此类矿体不能依靠自重迁移,因此开采时顶板管理难度大,开采成本高,是一项技术难题。文章分析了充填采矿法、崩落法与房柱法三种缓倾斜中厚矿体采矿方法各自的优缺点和适用条件,详细阐述了采矿方法的选择依据并着重介绍了充填采矿法的最新研究进展,以期能够为后续缓倾斜薄中厚矿床开采方法的选择提供指导。Because the inclination of the thick ore body is small,and there is a weak interlayer in the middle,the mining of such ore body can not rely on the weight of migration,so the roof management is difficult and the mining cost is high,which is a technical problem.This paper analyzes the advantages and disadvantages and application conditions of filling mining method,collapse method and house column method,expounds the selection basis of mining method and introduces the latest research progress of filling mining method.This work can provide guidance for the selection of mining methods for slow,medium and thick deposits.
