Abstract

Abstract:

Based on the background of Xihe Mine in Shanxi Province, using geotechnical engineering mechanical analysis calculation software FLAC3D, the surrounding rock stress field and the falling condition of the overlying strata in small coal mining broken area were analyzed, and on this basis, the optimum placement for the floor roadway excavation was determined, the roadway support scheme and the roadway support measure in special condition were put forward, successfully guided the floor roadway layout and supporting in coal seam broken area and has important theoretical and practical significance.

Key words: residual mining, floor roadway, roadway layout, roadway support
