Coal mining Underground mining | Britannica
Coal mining Coal mining Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities ...

The Benefits of Bulk Emulsion Explosives in Underground ...
This paper examines the practical and economic benefits of using bulk emulsion explosives in underground development mining; compared to ANFO, ANFO derivatives and packaged explosives. The key economic benefit of bulk emulsion is the replacement of relatively high cost packaged explosives with a bulk product. Key practical benefits include water resistance, improved coupling of explosive,...

What is Shaft Mining? (with picture) wiseGEEK
19/09/2020· Shaft mining—also referred to as shaft sinking—is a type of mining process used to vertically gain access to an underground mining facility. There are many different components which make up the shaft, all of which play a very important role in the mining process. The entrance to a shaft can go by different names, depending on whether or not the entrance is above or below ground. If it is ...

Communications to cages and elevators in vertical and slope shafts use the same system. Despite their capabilities, hardwired communications systems are generally not robust. The typical network configuration for a hardwired phone system is the bus structure shown in Figure 26. The connecting wires are easily broken or shorted by rock falls. Once a line is shorted, the communications may be ...

Deformation Failure Mechanism of Deep Vertical Shaft .
Vertical shafts play an important role in the safe operation of mines. The stability of vertical shafts has always been a difficult problem in mining engineering, especially with the increasing of mining depth. In order to keep the engineering works stable, it is necessary to make the deformation failure mechanism of vertical shafts clear. This paper describes a case study of the deformation ...
