采煤工作面使用柱鞋的分析与设计

Analysis and Design of Hydraulic Prop Shoes Used at Coal Face

在煤矿炮采、普采工作面开采遇到底板松软时,单体液压支柱容易插入底板。为了减少单体液压支柱插入底板量,文章作者设计了一种新型柱鞋,既提高了工作面支护效果,又便于柱鞋的回收。

At the blasting or general coal face, when the bottom floor is soft, the single hydraulic prop is easy to insert in the bottom floor. In order to reduce the amount of inserting in the bottom floor of hydraulic props, a new type of hydraulic prop was designed. Not only the face supporting effect was improved, but also the recovery of prop shoes was convenient.
