Abstract

In order to mine efficiently and safely in upper coal seam working face, upper mining of 2394 working face in Donghuantuo Mine was studied and optimized, the concrete position was settled by relative technology theory and actual experience, with obvious effect and valuable experience, which provided technical data and relative experience of upper mining.

Key words： upper mining working face design boundary corner protection coal collumn
