Research and application on the support technology of deep soft surrounding rock horse head door roadway
LIU Long
Abstract：Based on the destroy of thousand deep horse head door roadway, the deformation destroy and sup-port technology property of large section soft roadway were analyzed, the support technology rule and scheme of suitable to deep soft roadway were improved and applied in coal mine in-site.By analyzing to the deforma-tion, supporting material force and concrete strain of deep soft horse head door, all of the data change to stable and in the safety scope, result showed the support scheme were suitable to the deep soft roadway deformation property, gain the batter technology and economy result, and with the application value in approximately same roadway conditions.
