摘要
介绍了工作面两巷端头超前支护现状,提出了综采工作面两巷端头超前支护方案,即采用多组自移式液压支架对综采工作面两巷端头进行超前支护,该方案解决了工作面两巷端头20 m范围内的超前支护安全问题,提高了支护装备的机械化水平。
This paper introduces the present situation of the advanced support at the ends of intake airway and return airway of mining face, and puts forward an advanced support scheme, which solves the safety problem of the advanced support within the scope of 20 In of the ends of the ends of intake airway and return airway of mining face and raises the level of the mechanization of supporting equipment through adopting multiple sets of self-advancing hydraulic support for the advanced support at the ends of intake airway and return airway of fully mechanized mining face.
