    • Abstract
  • Through the analysis and comparison of dual-channel type fully mechanized main, auxiliary withdrawal support construction technology before end mining and blasting and mining machine with the construction of single withdrawal support channel after end mining, combined with large mining height support type, withdrawal support transport equipment, digging machine tunneling parameters, it selected reasonable withdrawal support channel construction technology according to the pressure law of the mine roadway itself and the deformation characteristics of the surrounding rock, achieved the process of joint construction withdrawal support channel of digging machine and coal mining machine.
