综放工作面沿空布置切眼技术研究

摘要

The arrangement of open-off cut of fully mechanized caving face along gob is bold exploration and beneficial practice of roadway layout and construction technology. this paper discussed the supporting principle, supporting parameters, and construction technology of small coal pillar along gob from the theory and practice, analyzes and summarizes the good supporting results in practice, which arranged the open-off cut of fully mechanized caving face along gob, have important guiding signiifcance for construction the fully mechanized caving face open-off cut.%综放工作面沿空布置切眼是一次巷道布置和施工技术方面的大胆探索和有益实践。本文从沿空小煤柱支护的原理、支护参数、施工工艺三个方面进行了较为深入的理论和实践探索，分析并总结了深井综放工作面沿空布置切眼支护在实践中取得了很好的效果，对综放工作面开切眼的施工有较为重要的指导意义。
