The invention relates to a mining method of a single-layer vein and a mining method of the vein. The mining method of the single-layer vein comprises the steps that a, a plurality of cutting wells are constructed along the tendency of the vein, and the cutting wells are arranged at intervals along the trend of the vein; b, layer-by-layer stoping is conducted on the vein in the lateral direction of the cutting well in the cutting well in the direction of the vein; and c, after each layer of lateral stoping is completed on the vein along the trend of the vein, filling the stoped layer of space of the vein. Layered stoping is conducted in the cutting well towards the side face, the stoped space is filled after stoping of one layer is finished, and therefore it is guaranteed that only a small part of space of the vein is in the mined-out state all the time in the stoping process, ground pressure can be effectively reduced, and the problem that the vein collapses due to the fact that the mined-out space is too lar
