For there is no much practice of steep uphill tunneling in rapid driving with mechG anized comprehensive supporting,through reasonably selecting excavation equipment,improving the hydraulic system of roadheader,optimizing the tunneling construction process & cutting mode and building artificial platform and other measures,Tangshan Mining Branch Company of Kailuan Group has achieved the steep uphill mechanized tunneling with average of 26°and maxiG mal angle of 29°in Y485 working face,which has broken the constraints of steep uphill construcG tion of the roadheader,and explored the construction technology and process for the steep uphill mechanized tunneling.
