Comprehensive coal-mining process by using long wall mining method

The invention relates to a long-wall coal method, which can be used in stable coal bed, rigid top plate, non-broken incline middle-thickness coal bed, and thick coal bed layered long-wall method. Wherein, it arranges hydraulic support, scrape transporter, and roller coal machine at the long-wall working surface; arranges groove transporter and flexible band transporter at the transport channel; the working surface has ultra long length, which is two times of integrated coal surface; it uses two coal machines on one scrape transporter, to scrape the upper half surface and the lower half surface; and it can arrange middle channel at the middle of integrated surface as the transport channel; and arranges scrape transporters at the upper and lower half working surfaces. The invention has high efficiency, while it can reduce the digging rate and improve the resource recycle rate.
