The Research On Structure And Key Technology Of Temporary Support Equipment Used In Rectangular Roadway

At present excavation and support of the mine roadway have no good cohesion thathas greatly affected machine tunneling efficiency and mining speed. Because tank andcut eye are all rectangle. In order to solve this problem，we develop a self advancingroadway temporary support equipment which sets temporary support and spread anchornet at a suit. Its top beam is network design. The temporary support can be set into thebolt that will connect temporary support with permanent support it improve the machinedriving efficiency.Firstly we begin to calculate the coal rock rectangular roadway in mechanicalproperties and numerical calculation through the comparative we take the maximum. Weget the roadway roof calculation method. And according to the actual situation ofroadway, we put forward rectangular roadway anchor net support methods. At the sametime we base on calculation method to design the temporary support structure.Temporary support equipment design concept is to use existing products on the marketas the temporary support equipment components. It will realize temporary supportmovably. It meets the strength requirement at the same time, it also need the lightweight, the simple structure to guarantee the practicability. When temporary supportequipment design is completed, we use ANSYS Workbench to analysis the roof beams.When the bottom is rough, we use ANSYS Workbench to analysis the base. Wecomplete to check the roof and base intensity in the most dangerous situation. It willprovide theoretical basis for the rationality design. Finally, we use ANSYS Workbenchto optimize the base and beams. It will optimize the structure.
