Temporary Support Technology of Roadheader

Temporary supporting is a requisite working procedure for bolting work in fully mechanized mine roadway heading face.The reliability of temporary supporting affects directly safety of bolting work.Temporary supporting technology was one of the key factors that restricted fully mechanized mine roadway excavation.Adding a supporting device to the roadheader has totally changed the traditional supporting method.Because the device effectively supports the roof,the miners are no longer working in an unsupported area as usual,which dramatically improves the safety of a mine.With the help of the device,supporting metal net can also be easily put when it is necessary.It will stretch out when be used and will fold after using.It is hydraulically driven and very helpful to save time and improve efficiency of supporting.The device can be optionally added to the different boom-type roadheaders from EBZ100 to EBZ260.
