Mining methods & equipments - Mining | Liddell Coal

Truck and excavator mining method is the primary method currently utilised. The sequence of mining involves clearing and stockpiling of vegetation and topsoil; drilling and blasting of overburden; excavation and haulage of overburden from a series of sequential mining blocks to the emplacement areas; coal excavation and haulage; and rehabilitation of overburden emplacement areas.

What types of plant are found on mining operations?

Plant can be described as being either fixed (e.g. conveyor) or mobile (e.g. truck). The term plant is defined in Part 1, Section 4 of the Mines Safety and Inspection Act 1994. High risk work licences are required to operate certain types of plant (e.g. some cranes, fork lifts, elevating work platforms, boilers).

Mining Methods Environment Guide

Mining Methods. There are four key stages of work involved in mining for minerals. These include: 3415, 3416 Prospecting The purpose of this stage is to identify areas that are likely to contain mineral deposits. The work includes geological, geochemical and geophysical surveys (e.g. seismic surveying), aerial surveys, including the taking of samples by low-impact mechanical methods.

Open-pit mining - Wikipedia

Open-pit mining, also known as open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful ore or rocks

Coal mining - Choosing a mining method | Britannica

Surface coal mining generally involves the following sequence of unit operations: (1) clearing the land of trees and vegetation, (2) removing and storing the top layers of the unconsolidated soil (topsoil), (3) drilling the hard strata over the coal seam, (4) fragmenting or blasting the hard strata with explosives, (5) removing the blasted material, exposing the coal seam, and cleaning the top of the coal seam, (6)

3419 Techniques which may be utilised include blasting, excavators, and, in the case of underground coal mines, high-pressure water cannons. 3420 Techniques for mining minerals in the marine environment may involve seafloor suction dredging, seafloor slurry pipes, use of tracked vessels on the seafloor and seafloor cutting/fragmentation. Following extraction and processing, tailings (unwanted material) are

Digging deeper: Mining methods explained | Anglo

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them

Appendix E: Coal Mining and Processing Methods | Coal

Room-and-Pillar Mining. In the room-and-pillar method, a set of entries, usually between three and eight, are driven into a block of coal. These entries are connected by cross-cuts, which are usually at right angle to the entries. The entries are commonly spaced from 50 to 100 feet apart, and the cross-cuts are usually about 50 to 150 feet apart.

Methods and Techniques of Uranium Mining - Nuclear

As with other types of hard rock mining there are several methods of extraction. In case of uranium mining, it strongly depends on the concentration of uranium in the ore. For example, the ore extracted from the Australian Olympic Dam Mine has a concentration of 0.05 %.

Mining - Wikipedia

Other methods include shrinkage stope mining, which is mining upward, creating a sloping underground room, long wall mining, which is grinding a long ore surface underground, and room and pillar mining, which is removing ore from rooms while leaving pillars in place to support the roof of the room.
