浅埋深综采工作面收尾回撤通道锚网索支护技术应用

Application of Anchor Cable Support Technology for the End Retracement Channel in Shallow-buried Fully-mechanized Mining Face

以串草圪旦煤矿5102工作面为例,对浅埋深综采工作面收尾回撤通道锚网索支护技术的应用进行了探讨。通过利用工作面采煤机自开通道,顺序施工锚网索支护巷道,并在上下出口架设锚索U型钢梁,有效控制顶板,为工作面快速拆除创造了有利条件。

Taking the 5102 working face of Chuancaogedan Coal Mine as an example, this paper discussed the application of anchorage cable support technology for the end retracement channel in shallow-buried fully-mechanized mining face. The channel is self-opened by using the working face shearer, the anchor cable is used to support the roadway in sequence, and the U-shaped steel beam of the anchor cable is installed at the upper and lower exits to effectively control the roof, which creates favorable conditions for the rapid removal of the working face.
