Abstract

Combining with the equipment removing and finish work of 11413 fully mechanized mining face in a mine in Huainan Mining Area, adopting anchor net support technology and the secondary bottom discharge method of coal mining machine can quickly form the support-removing channel based on optimizing the condition preparation of finish work. The adoption of support-removing without pitwood can greatly improve the removal efficiency of the support, shorten the closing time of the working face, reduce the goaf ignition hidden danger, and save the material cost while improving the safety.
