Abstract:
A longwall N00 mining method includes performing a no-entry excavation and non-pillar mining in N working faces of a new district, and the whole district is provided with an air-return dip, a haulage dip and a track dip, wherein the air-return dip and the track dip are located on one end of the district, and the haulage dip is connected to the other end of the district, and connected to the air-return dip. This method can not only ensure ventilation of the whole coal cutting are, but also when mining is performed in each working face in the district, entries can be automatically formed due to top-cutting pressure release by using a part of a gob area, and thereby it is not required to separately excavate any gateroad entry during mining coal nor need to retain any coal pillar, so as to save resources and improve efficiency.

Claim (Index 7):
The longwall N00 mining method according to  claim 6 , wherein, a wood plate is arranged on the hydraulic prop.
