The underground filling method drills large deep holes from one side to the other side using the machines like tunnel boring machine (TBM), where all the drilling holes pass through the center of the mining asteroid. The waste produced from the open cutting method and drilling holes can be used to fill the mined-out areas.

Mining - Drifts, Tunnels, Shafts: All horizontal or subhorizontal development openings made in a mine have the generic name of drift. These are simply tunnels made in the rock, with a size and shape depending on their use—for example, haulage, ventilation, or exploration. A drift running parallel to the ore body and lying in the footwall is called a …
