摘要
本文通过对普通漏斗电耙底部结构优缺点的分析,提出了新型无颈堑沟电耙底部结构形式,并通过理论分析和实践验证都说明了这种底部结构形式是可靠的,可以在有底柱崩落采矿法中推广应用。
Through analysing strong and weak points of bottom structure of ordinary funnel electric rake,puts forward the bottom structure form of new non neck trenching electric rake.Through theoretic analysis and practical operation,the result explains that this bottom structure form is reliable and it can be used in sill pillars sublevel caving method.
