Here, Miners observed many instances where underground mining is more costeffective than surface mining. Underground mining is more costeffective when the
Modeling and dynamic behavior analysis of a coupled multicable double drum winding hoister with flexible guides. Mechanism and Machine Theory, Volume 108, , pp. 191208. Coal bump refers to a sudden catastrophic failure of coal seam and usually can cause serious damages to underground mining facilities and staff. In this
Improve the existing model of power supply of the underground substation in static and dynamic modes of its operation and perform simulation of static and dynamic emergency modes of its operation.The paper is devoted to determining the possibility of modeling static and dynamic emergency modes of operation for a sectional underground substation
The most common types of mining equipment vary depending whether the work is being carried out above or below ground or mining for gold, metals, coal or crude oil. From drilling machines to
Underground Mining–Shaft Equipment. 6.2.1 DRUMS AND SHEAVE WHEELS Drums and sheave wheels should be designed and manufactured in accordance with AS 3785 Underground Mining–Shaft Equipment. 6.2.2 FENCING, GATES, SHAFT ENTRANCES SUPPORTED All shaft entrances from the bottom of every shaft to the
For very selective mining, miners use hand held drilling equipment called airlegs (Fig. 2b). Another standard underground machine is a loadhauldump machine or simply LHD (Fig. 2c) used for loading the broken ore from the draw points of the stopes and tramming (hauling) it to the nearest ore pass or loading a truck.
The task of ore transportation is performed in all mines, regardless of their type (open pit/underground) or mining process. A substantial number of enterprises utilize wheeled machines to perform ore haulage, especially haul trucks and loaders. These machines’ work consists of repeating cycles, and each cycle can be divided into 4 operations: loading,

(2014). Analysis of the impact of increasing mining rate in underground mining using simulation and mixed integer
Cat AD63 is a highcapacity underground articulated truck that has been manufactured in the United States it is used to transport large quantities of material from inside or outside the mines to storage locations it is designed to provide maximum productivity at the lowest operating cost it measures 12.4 meters long by 3.3 meters wide
Transformers are used extensively at mines, both on the surface and underground. In order to keep voltage drop to a low value without using large cables, the electrical power is distributed at 3,300 volts or 6,600 volts. This voltage, while ideal for distribution, is too high for use on coalface machines or the smaller machines elsewhere
It is important that the strategic mine plan makes optimum use of available resources and provides continuous quality ore to drive sustainable mining and profitability. This requires the development of a wellintegrated strategy of mining options for surface and/or underground mining and their interactions.

Drones. Underground mining drones, like Flyability's Elios 3, are used for visual inspections in stopes, ore passes, ventilation shafts, conveyor belts, and other areas of an underground mine.. Drone technology has allowed inspections to be conducted in areas that are unsafe for humans to enter, presenting an invaluable tool in such

The failure of a mining rope poses a serious risk to mining workers, winding equipment and the mining shaft itself. In order to cope with the mine’s harsh environment, Bekaert’s mining rope wire is created with an optimal

Cut and Fill. It is a shorthole mining method, used in ore zones that are irregular or steeply dipping. The ore is dug out in slightly inclined slices or horizontally. And sand will fill it, waste rock, or tailing. This method is a selective and expensive one. It has the advantages of low ore dilution and loss.
High Angle Conveyor system suffers no loss of capacity with increasing shaft depth. 5. High Angle Conveyor system exhibits high availability and very low maintenance costs. 6. The economic advantage of continuous haulage with High Angle Conveyors increases dramatically with increased volumetric rate. 7.
