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.
Underground mining has historically occurred in surface and near-surface (shallow) mineral deposits. While no universal definition of deep underground mining exists, humanity's need for non-renewable natural resources has inevitably pushed the boundaries of possibility in terms of environmental and technological constraints.

By reviewing the development status of the Chinese directional drilling technology in coal mine in recent years, the authors described the performance characteristics and R & D direction of directional drilling equipment at home and abroad, and analyzed the key equipment of directional drilling and drilling technology.
Full-face tunnel boring machine (TBM) tunnelling has unparalleled advantages over conventional drill-and-blast (D&B) techniques in terms of higher advance rates and lower risk levels in favourable ground conditions. However, there are only a few successful TBM applications in mines.
The tunnel boring machine (TBM) is used extensively to mechanically excavate tunnels. To optimize the mechanical drilling and work safely, an estimate of the geology to be drilled is necessary. We consider using the elastic waves produced by the TBM cutting wheel to obtain seismic-while-drilling (SWD) information for predicting the …

To understand the characteristics of the TBM drilling noise, field tests were conducted in the Jinan subway project. Based on the near-surface investigation and borehole geological exploration, the geology along the subway line was found to be composed of alternating soft and hard rocks, mainly containing granite with different …
Master Drilling is readying its Mobile Tunnel Borer (MTB) technology for a contract at Anglo American Platinum's Mogalakwena mine in South Africa.
Such methods are time consuming and add expense. As a result, most mines excavate mining drifts and access tunnels through slow and arduous drill-and-blast techniques. Robbins, headquartered in Solon, Ohio, has now developed a non-circular tunnel boring machine, the MDM5000 (Mine Development Machine), to address these …
