Beschreibung
Zusammenfassung:The invention discloses a fully mechanized caving face upper end double-staggered arrangement method which comprises the steps that in the space from the upper section to the end of a working face, an end support with the supporting height suitable for the total thickness of a coal seam, a first transition support, a second transition support and a top coal caving support are arranged in a staggered mode based on a working face bottom plate. Under the condition of a fully-mechanized top coal caving working face of top touching tunneling and bottom exploration, the arrangement method can recycle triangular coal at the bottom of the upper end of the fully-mechanized top coal caving working face, and the coal recycling rate is increased. 本发明公开了一种综放工作面上端头双错布置方法,包括:在工作面上段至端头的空间内,采用支撑高度适用于煤层全厚的端头支架、过渡支架一、过渡支架二以及放顶煤支架基于工作面底板错落布置。本发明在摸顶掘进、摸底回采的综采放顶煤工作面的条件下,该布置方法能够实现回收综放工作面上端头底部三角煤,提高煤炭回收率。
