潘二矿薄煤层综采工作面旋转回采技术总结

摘要

The exploitation of coal as a protective layer has been made to the liberation of the protective layer, so that a smooth protective layer recovery, Huainan Coal Mining Group II Pan Groove 5 for thin seam of coal, mining as a protective layer, the average coal seam thickness of 1.1 m, 5 groove complex geological conditions of coal, construction and development more. The right to choose the right technology and the production of mining equipment is to ensure a smooth thin seam mining an important prerequisite not only for a thin seam mining, and the liberation of the coal chute 4.%淮南矿业集团,潘二煤矿施工的11125薄煤层综采工作面施工沿方位N119°推进430m后,回采方位改为N137°,为了更好的保证转采期间的工程质量管理,合理的采取煤机割煤方式,对煤机的割煤方式进行调整,并始终保证工作面平、直、稳的要求,确保工作面顺利转采。
