Mining engineering is divided into colliery Lei Hefei collieries class mining (English names：Ore mining) it is from the earth's crust or earth's surface
The technology and science of exploit mineral resources.Refer generally to the exploitation of metal or nonmetal depdosit, the mining of broad sense also includes coal and stone
The exploitation and ore dressing of oil.Its essence is a kind of collection of the selectivity of material and handling process.Mining industry is a kind of important original
Expect extractive industry, such as metallic ore is the primary raw material of metallurgical industry, non-metallic ore is industrial chemicals and construction material, coal and
Oil is the important energy.Most ores need to can be used as the raw material of industry through beneficiation enrichment.
The basis of mining science and technology is catalase, bulk material migration, fluid conveying, mine rock mechanics and mining industry
System engineering scheduling theory.Need with subjects such as mathematics, physics, mechanics, chemistry, geology, systematic science, electronic computers
Newest fruits.Mining industry on the basis of the high mechanization basically reached, by improve the design of fully-mechanized mining equipment, moulding,
Material, manufacturing process, the method for inspection and maintenance etc., will further improve its production capacity and utilization rate of equipment and installations.While ore deposit
Well will realize automation and remote control in many links such as lifting, transport, draining, ventilation, gas-monitorings.Underground and opencut all will
Realize that computer concentrates automatic management and monitoring.Some countries try out robot in underground stope, exploit to personnel
The larger mineral of infringement.On the other hand, the continuous exploitation with the mankind to underground mineral, from high to low, resource is tight for mining grade
Lack, force using low-grade mineral products, the appropriate mining of selection and beneficiation method, progress integrates selecting and purchasing, comprehensive utilization, improves mineral products
The utilization rate and the rate of extraction of resource, reduce the loss late and the rate of dilution of ore.Mining and ore dressing process in generate toxic gas,
The factor such as the materials such as waste water, barren rock and dust and noise and vibration, causes harm to environment, soil, air and water quality etc., and one
It is directly the problem that people are concerned about.The long-term Utilizing question of resource is further provided in various countries' research environmental issue, is especially had in mind
In land reclamation etc. after waste residue, barren rock, the reuse of waste liquid, destruction.Strong law is worked out, adopting an effective measure ensures
Mine environment.
