Underground Construction (Tunneling)

The OSHA underground construction regulation (29 CFR 1926.800) applies to the construction of underground tunnels, shafts, chambers, and passageways. It also applies to cut-and cover excavations connected to ongoing underground construction as well as those that create conditions characteristic of underground construction.

Chapter 13 Underground Surveying Engineering360

In an underground transport system, for instance, the tunnels are driven to connect inclined or vertical shafts (points of surface entry to the transport system) whose relative locations are established by surface surveys. Thus the underground control networks must be connected and orientated into the same coordinate system as the surface networks.

State of the art and vision During the deployment of the shaft sinking equipment in Kuwait, a total of five 15 to 27 m deep shafts with 8 m diameters was constructed. The jobsite team familiarized themselves quickly with the new technology. On the first construction day, 2 m of shaft could already be built.

Excavation MethodsVertical Shafts Introduction

Excavation Methods. Vertical Shafts. There are 4 methods in general use Conventional drill, blast & remove stone ("muck out") to surface with a winder.If the shaft is to be "lined" (i.e. sides to be covered with a concrete or even a steel lining), this is normally placed as the shaft is excavated.

The vertical shaft is the most risky mine entry. You should be aware of the dangers of a bad collar on the shaft, some shafts just shouldn't be entered, if in doubt don't do it. Any time you are in the shaft while descending or ascending you are potentially in the path of any falling object from above.

Shaft Mining, Mining Techniques, Underground Mining

Shaft Mining. Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It is found mostly all over the world.

Mine Shaft Sinking Methods

Conventional mine shaft sinking methods involve the performance of a cycle of different operations—drilling and blasting, removal of smoke and cleaning of fly-rock lodged on overhead timbers, mucking and hoisting of the broken rock, and timbering. The latter (a) may be the last operation of the cycle, (b) may be carried on during drilling and mucking, provided it is done from a substantial
