Mining is the process where minerals or other geological materials are extracted from the earth, from an orebody, lode, vein, (coal) seam or reef. This eventually is the platform for a miner/ mining company to gain monetary benefits and commercialize the output of the activity.
Mining operations are differentiated into five major categories based on their resources such Oil and Gas extraction, Coal mining, Metal ore mining, Nonmetallic mineral mining and Quarrying, and Support activities for mining.
Mining is carried out to discover materials like base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock salt and potash, which cannot be grown through agricultural processes, or created artificially in a laboratory or factory. It also includes extraction of any non-renewable resources (e.g., petroleum, natural gas, or even water).
COUNTRIES focusing on Mining:
Many countries carry out Mining, but USA, Canada, Australia, South Africa and Chile have become the leaders in mining, exploration methods and technology across the globe.
There are two common excavation types of mining techniques such as Surface Mining and Sub-Surface (underground) Mining.
Surface mining is much more common. Targets are divided into two general categories of materials: placer deposits and lode deposits.
Placer deposits include valuable minerals contained within river gravels, beach sands, and other unconsolidated materials.
Lode deposits comprise of valuable minerals that are found in veins, in layers, or in mineral grains generally distributed throughout a mass of actual rock.
Underground mining is executed when the rocks, minerals, or precious stones are located at a distance far beneath the ground to be extracted with surface mining. The miners construct underground rooms to work in, to assist the minerals to be taken out of the mine.
Two prominent ways through which underground mining is done are: Underground mining (hard rock) and Underground mining (soft rock), which requires different techniques.
The other mining methods are shrinkage stop 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 which is removing ore from rooms while leaving pillars in place to support the roof of the room.
Generally the act of extracting is performed by the government authority, individual entrepreneurs or may be by small business owners as the entire process of extraction requires a large amount of capital.
Since 1955, the World Bank has been involved in mining, primarily through grants from its International Bank for Reconstruction and Development, with the Bank’s Multilateral Investment Guarantee Agency offering political risk insurance.
Some of the major bodies engaged in mining industry are employment, machinery, business and safety of the workers.
A wide number of individuals are directly or indirectly involved in mining industry. The individuals involved directly with this mining industry are workers who perform activities such as digging, extracting etc, while the indirectly involved are accountants, lawyers, sales representatives etc.
Heavy machines play a vital role in Mining industry to implement explosions, digging, etc. The machines are used to break or remove rocks, drilling and a specially designed wagon is used for conveyance purpose which operates on tracks in a mine to transport mine workers, minerals and wastes.
Safety issue is one of the main concerns of mining industry, as poor ventilation, some poisonous gases and toxicants can severely harm miners’ health, which may also cause trauma or even death to the miners.
The government plays the role of a regulatory body that facilitates clear policies and guidelines in order to boost the allied sectors and various stakeholders. The government plays a vital role of responsibility towards the general development of the industry and its dependents.
Opportunities within the mining industry are floated through government Tenders and Projects worldwide.
Examples of the kind of Tenders floated can be like:
Mining tenders, coal mining tenders, mineral mining tenders, Provision of Mining operations in affect road, Vehicle restraint systems, mining and temporaries, Supply of Consumables of mining drilling, Development of a Sustainable Mining Development Policy, Consultant Services for Legal and Policy (Review and Development of Mining (Safety) Act Regulations), Supply of mining flameproof switch-gear, Technical assistance in planning specific mining engineering and many more.
