Coal mining Choosing a mining method Britannica

Social factors include prior history of mining in the area, ownership patterns, availability of labour, and local or regional government support. It is a general rule that technological factors dictate a clear choice between surface and underground mining, whereas economic and social factors determine whether a coal reserve will be mined at all.

What are the next steps? Ongoing research efforts to control airborne contaminants or develop sampling instrumentation include the following:

3 Technologies in Exploration, Mining, and Processing

Surface mining methods can be broadly classified as open-pit mining, which includes quarrying, strip mining, contour mining, dredging, and hydraulic mining. Topography and the physical characteristics of the deposit strongly influence the choice of method.

Factors Affecting Exploitation of Mineral Resources around

Major factors affecting exploitation of mineral resources in the world are as follows: (i) Richness or Grade of the Ore (ii) Size of Deposit (iii) Method of Mining (iv) Accessibility (v) Transportation Facilities (vi) Stage of Industrial Development (vii) Technology (viii) Other Factors.

Topic 5: Mining Methods-Part I-Surface mining

Mining conditions The geometry of an ore body and the topography of the land surface beneath which the ore body exists will affect the kind and cost of a surface mine. The depth and character of overlying rock and the physical characteristics of the wall rock also affect the configuration and cost of a surface mine.

Opencast Mining an overview ScienceDirect Topics

The open-pit or open cast mining method is the obvious choice for a property with wide area of mineralization exposed or exists close to the surface and continues to greater depth. The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks.

ANALYSIS OF TECHNICAL FACTORS FOR UNDERGROUND

experience is the most applicable to the underground mining of the Waterberg reserves. It is probable that total extraction using longwall will be the correct choice of mining method. Finally, this dissertation has illustrated the essential need for fundamental research if

Models for Mining Equipment Selection

The Mining Method selection problem focuses on choosing the correct excavation method for the given mining conditions. Generally, this research is based on anecdotal methods, where a feasible solution is sought, rather than an optimal solution. Much of the literature on mining method selection does not discuss equipment selection modelling in

knowledge and practice in highwall mining (HWM). HWM has become a widely-applied method in surface mining, commonly used alone or in conjunction with contour or slot mining. It provides 800-feet to 1,200-feet of additional recovery when the economic stripping ratio is reached in contour mining or in slot mining when surface
