Harm of mining

1.

It will accelerate the aging of graphics card

in order to make money, the graphics card works continuously for 7x24 hours and runs at full load. Some people will overclock the graphics card in order to earn more money. The general home game graphics card is not designed for this kind of use environment at all. Long time full load operation will lead to accelerated aging of the graphics card, Generally, the life of the graphics card used for half a year of mining is longer than that of the normal use of the players for three years, so now the major brands have made strict restrictions on the quality assurance of the cards

principles of computer Mining:

starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique. In the metaphor of banknotes, bitcoin is the number of the top word of a banknote. If you know the number of the top word of a banknote, you will have the banknote

and the process of mining is to constantly seek the special solutions of the equations through huge amount of calculation. The equations are designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million

to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client

after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost

2. Mining with the graphics card in the computer requires a long-time operation of the computer, and the graphics card needs a lot of calculation. Compared with the normal use of the computer, it will have greater loss, and the service life will be greatly reced. At the same time, long-time operation, the hardware also emits a lot of heat, if the heat dissipation is not good, it will affect all the hardware

3. The impact of mining proction on the environment includes soil erosion, land subsidence caused by mines, destruction of biodiversity and groundwater pollution caused by wastewater containing chemicals in the mining process
the state has strict laws and regulations on environmental protection and restoration of the surface state of mining instry, which ensure that the mining area should be restored to its original state, or even better than the environment before mining. In countries where the past mining methods are not strictly restricted, the mining instry will cause irreparable harm to the environment and affect human health.

4. Iron ore is one of the earth's mineral resources that people exploit, and it is also used more. Excessive exploitation of iron ore will cause the following problems: (1) over exploitation or even full exploitation of iron ore in a certain area will lead to the formation of fault subsidence, subsidence or the entry of groundwater. (2) there will be environmental pollution Now, it is rare that the main iron ore is to be smelted, which will proce waste slag and exhaust gas and pollute the environment
for the whole earth, I don't think it's a big problem. After all, the distribution of iron ore is not concentrated in a certain area of the earth (such as the oil in Western Asia), but only partially changes the natural environment near the surface, which will not have much impact on the earth.

5. Because the second-hand mine card is in full load working state for a long time, the original of the graphics card is aging, the life of the graphics card is shortened, and the stability is reced. It is easy to appear problems such as screen crash. If you are lucky, you can use it normally.

6. The harm of unreasonable mining, I think, has certain harm to us and the natural environment, so we must abide by the rules.

7. What are the main occupational hazards in machinery manufacturing instry

there are mainly: proctive st in foundry; High temperature and thermal radiation; Harmful gases, such as melting metal and casting, can proce carbon monoxide; And noise, vibration, etc. High temperature and heat radiation in forging workshop; Harmful gases of carbon monoxide and sulfur dioxide; And noise, vibration, etc. Heating furnace and salt bath in heat treatment workshop can cause high temperature and thermal radiation, and high frequency electric furnace can cause high frequency electromagnetic field damage. There will be metal and mineral st in machining workshop. The assembly workshop generally has welding, electroplating, painting and other operations, long-term inhalation of high concentration of welding st can cause welder pneumoconiosis; In addition, if you don't pay attention to eye protection ring welding, you can have electro-optic ophthalmia; Benzene, toluene and xylene poisoning may occur ring painting

What are the main measures to prevent occupational hazards in machinery manufacturing instry

first, the design layout of the workshop should comply with gbzl-2002 "Hygienic standard for instrial design", so as to prevent the cross pollution of occupational hazards among various processes and types of work. For example, the melting furnace in the casting process should be placed outdoors or far away from the place where people gather; Riveter, welding and painting process should be arranged separately. Secondly, the sand with low free silicon dioxide content should be selected for casting, and manual molding and sand cleaning should be reced; Water blasting and sand cleaning should be adopted to remove sand. Large power ventilation and st removal system should be installed to spray wet operation to rece the st concentration in the air of the workplace. Workers should wear anti st masks that conform to the national standards. Third, for the equipment procing chemical poisons in the process of heat treatment and metal smelting, it is necessary to take sealing measures or install local ventilation device; For some workplaces where quenching, electroplating, painting or adhesive are easy to proce high concentration of toxic and harmful gases, emergency rescue plan for acute occupational poisoning should be formulated, warning signs should be set, and relevant operators should wear gas masks or gas masks ring operation. Four is to do a good job in casting, forging air hammer, air compressor, mechanical processing of grinding, polishing, stamping, shearing, cutting and other high-intensity noise equipment governance. For high-intensity noise sources, centralized noise prevention measures can be taken, and sound insulation shield can be set; For aerodynamic noise sources, noise elimination measures should be taken at the inlet or outlet; Sound insulation and absorption measures shall be taken for centralized control room and post operation room; When entering the workplace with noise intensity over 85dB (a), operators should wear anti noise earplugs or earmuffs. Fifth, for riveting, forging press, molding sand tamping machine, sand dropping, sand cleaning and other vibrating equipment, vibration rection measures should be taken for the equipment or rotation operation should be carried out for the operators. Sixthly, shielding measures can be taken to the equipment procing high frequency, microwave and other radio frequency radiation to isolate the magnetic field and shield the electric field; The radiation of microwave in the workplace can be shielded by two kinds of shielding methods: reflection type and absorption type. In addition, distance isolation protection measures and time protection measures can be taken for operators. The seventh is to prevent heatstroke of high temperature workers. For the high-temperature workers of casting, forging and heat treatment, a series of comprehensive preventive measures should be taken from the aspects of engineering technology, occupational health care, labor organization and management, such as reasonable arrangement and control of heat sources, supply of heatstroke prevention drinks, rotation operation, and setting air conditioning in the centralized control room and operation room.

Indiscriminate mining and abuse of mineral resources, harmful to the human body of mercury, lead, cadmium, arsenic and other elements, as well as radioactive elements, from the depths of the excavation, without proper treatment, let it scattered all over the surface, polluting the environment, and so on

Most of the wasteful and excessive exploitation is in the form of extensive exploitation, so the utilization efficiency is generally not very high

e to human destruction, the mineral resources are facing depletion. We need to save resources. After all, mineral resources cannot be regenerated

The classification of mineral resources in

extended data

mainly includes:

according to the genesis and formation conditions of mineral resources, it can be divided into endogenous mineral resources, exogenous mineral resources and metamorphic mineral resources

According to the material composition and structural characteristics of minerals, they can be divided into inorganic minerals and organic minerals

According to the output state of mineral resources, it can be divided into solid mineral resources, liquid mineral resources and gas mineral resources

according to the characteristics and main uses of minerals, they can be divided into energy minerals, metal minerals, non-metal minerals and water and gas minerals

Mining instry is one of the ancient fields in which human beings engage in proctive labor. The development of mining instry and the expansion of the exploitation and utilization of mineral resources have played an irreplaceable role in promoting the development and progress of human social civilization. The ancestors of the Chinese nation, like many other nations in the world, began to engage in mineral development and utilization activities from the date of their birth

historians divide human history into Paleolithic age, Neolithic age, bronze age and iron age, which are all characterized by the main types of mineral resources developed and utilized by people at that time
