【Abstract】 In this paper,two key technologies for the construction of inclined roadway in large-scale opencast coal mines are put forward:the technology of building ramps by throwing blasting and the technology of building ramps by bulldozer by means of downward grooving. The application of the two ramp construction techniques in Haerwusu opencast coal mine has obtained good effects,which not only improves the operation efficiency but also reduces the production cost,so it has very high popularization value.更多还原
