本发明公开了种长壁开采N00工法，其特征在于，在个全新盘区的N个工作面，实施种无巷道掘进，且无煤柱开采，整个盘区设置回风下山通道、皮带下山通道和轨道下山通道，其中回风下山通道和轨道下山通道位于所述盘区的端，所述皮带下山通道连通所述盘区的另端，并与所述回风下山通道连通。本发明不但可以保证整个采煤区的通风，而且在进行盘区中每个工作面开采时，利用采空区的部分，实施切顶卸压自动成巷，不再需要掘进任何顺槽巷道，也不再需要留设煤柱，从而节约资源，提高效率。 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 sa
