(57) Abstract: A tunneling-free and coal pillar-free mining and construction method wherein a coal mine field is not divided into 
mining areas. An upper main tunnel (1) and a lower main tunnel (2) are respectively arranged at upper and lower parts of a field, and a 
central air inlet inclined tunnel (15) is obliquely arranged at a central part. A first workface cutting hole (5) is arranged at the lower side 
of the upper main tunnel of a field boundary, a first workface (6) is arranged along the moving direction, and downward inclined mining 
is performed along the incline direction. The first workface is pushed downward to a lower boundary then moved to a cutting hole of 
- an adjacent replacement workface, to perform upward inclined mining to an upper boundary, and then moved again to a cutting hole 
of a next adjacent replacement workface, thereby moving up and down to perform cyclical pushing and mining. The method shortens 
the shaft depth, reduces the shaft construction period, and saves initial investment.
