Research on application of anchor-net combined supporting technology of the great span cut lane in Huang Sha Coal Mine
Abstract：Based on real engineering geology condition of the 2147 coal face in Huang sha Coal Mine,through theoretical calculation,design anchor-net combined supporting parameter of the 2147 coal face cut lane,and put forward some specific construction craftwork in construction process,and supply technical sustain for field construction of the cut lane.Supporting effect observation of the cut lane showed that displacement magnitude of the cut lane surface,abscission layer magnitude of the roof,and anchorage force size of the cable are all controlled within the adjacent rock deforming permitted dimension.The results indicate that the anchor-net combined supporting effectiveness of the cut lane is preferably,and satisfy service need of the cut lane.
