Rational nature management is a system of natural resources use, which is characteristic of intensive farming and has been actively introduced since the second half of the 20th century. Geological aspects of rational nature management include the choice of such methods for the development of minerals that ensure the most complete removal of mineral resources in the absence of extracted minerals, the creation of conditions for the restoration of renewable natural resources (mainly groundwater), land reclamation, the organization of waste-free production, and in the case of the technical impossibility or economic inexpediency of such a solution – the organization of waste storage, which minimizes the harmful consequences of such an event.

How we can classified the resources of the bowels of the Earth

Mineral resources, or resources of the bowels of the earth, which are also called minerals or mineral raw materials, like fuel and energy resources, are the basis for the development of modern industry and scientific and technological progress.

There is no unified classification of mineral resources. There is a fairly conventional classification by type of use:

Combustible fuel and energy: oil, natural gas, coal, oil shale, peat, uranium ore.

Ore:

– non-ferrous metal ores: aluminum, copper, nickel, lead, cobalt, zinc, tin, antimony, molybdenum, mercury;

– mining and chemical: apatites, salts, phosphorites, sulfur, boron, bromine, iodine;

– ores of rare and precious metals: silver, gold,

– precious and semi-precious stones.

Non-metallic:

– industrial raw materials: talc, quartz, asbestos, graphite, mica;

– building materials: marble, slate, tuff, basalt, granite;

– Hydromineral: fresh and mineralized waters;

– Gemstone raw materials;

– Mining and chemical raw materials.

Real situation, and depletion of mineral resources forecasts. How long will this amount last?

Many industries are wholly or partially based on mineral raw materials: ferrous and non-ferrous metallurgy, chemical industry, power plants operating on mineral fuel, construction industry, etc. The main branch of heavy industry – mechanical engineering with its many areas operates on mineral raw materials and mineral fuel. Further development of the world economy is inconceivable without the widespread use of fuel and energy and mineral resources.

To date, all fossil substances (solid, liquid and gaseous) and geothermal energy are concentrated in the upper parts of the earth’s crust. The average content of a chemical element in the earth’s crust is called the clarke of this substance. More than 99% of the mass of the earth’s crust is made up of clarkes of eight elements: oxygen – 47%; silicon – 29.6; aluminum – 8.1; iron – 4.7; calcium – 3; sodium – 2.5; potassium – 2.5; magnesium – 1.9%;

The extraction of mineral raw materials is significantly ahead of population growth. So, in the period from 1950 to 1970, the world’s population increased from 2.5 to 3.6 billion people, that is, approximately one and a half times. During this time the consumption of bituminous and brown coal, iron and manganese ores, potassium salts and phosphates has increased in the world by 2-3 times. The consumption of oil has increased 4 times, natural gas – 5 times, bauxite – 9 times, etc. Growth in demand for mineral raw materials is expected in the future.

 In 1970, the world consumption of metals per capita was 345 kg (including 331 kg – ferrous and 14 kg – non-ferrous).

 Throughout its history, mankind has withdrawn from the bowels about 50 billion tons of oil, 5 billion tons of iron, 125 billion tons of coal and many other minerals.

There are many contradictory forecasts regarding the “timing of provision” of mankind with certain types of mineral raw materials. For example, the American scientists G. Landsberg, L. Fishman and D. Fisher pointed out in 1965 that the provision of the United States with many important raw materials is significantly lower than the possible level of demand for them in 2000.

 According to some estimates of foreign scientists, the reserves of all metals will be consumed on the globe by 2500, and by 1990 the mining of lead, tin, as well as gold, silver and platinum will cease; before 2000—2100 – nickel, molybdenum, tungsten, copper; until 2100-2200 – manganese, cobalt, aluminum. According to other data, there will be enough aluminum for 570, iron for 250, zinc for 23, copper for 29, lead for 19, and tin for 35 years. Many of these predictions are not reliable. They were drawn up several times and turned out to be erroneous.

How human society and mining companies can prevent an immediate depletion of the Earth?

Complex measures for the rational use of minerals and the protection of subsoil include the following:

1. Ensuring the completeness of extraction of minerals during mining:

a) improving the quality of exploration work;

b) expansion of open pit mining;

c) the introduction of systems for the development of minerals with the backfill of the worked-out area;

d) separate excavation of minerals and rocks;

e) redevelopment of sites and deposits;

f) development and use of special methods and measures to reduce losses. 

2. Ensuring the completeness of extraction of minerals during processing:

a) increasing the degree of extraction of minerals by improving processing technology. These technologies include underground leaching, microbiological, physicochemical, hydrometallic and combined methods. For example, the microbiological leaching method promotes the extraction of copper from chalcopyrite by 80%, manganese up to 97.5%, and increases the extraction of gold from refractory ores by about 9 times. As a result of the improvement of technologies, the emission of harmful gases into the atmosphere is almost completely eliminated and the complex use of raw materials is ensured;

b) the use of pre-enrichment methods;

c) processing of dumps and waste;

d) additional extraction of useful components;

e) treatment of mine and waste water;

f) development of measures of economic incentives for more complete extraction during enrichment.

3. Rational use of mined mineral raw materials and products of its processing in the national economy:

a) saving resources is one of the ways of rational use;

b) secondary use of products of processing of mineral raw materials;

c) the maximum reduction in losses during the transportation of mineral raw materials, coal, etc.

Rational nature management is the best solution!

Rational use of natural resources should ensure the full existence and development of modern society, provided that the high quality of the human environment is preserved. This can be achieved through the economic exploitation of natural conditions and resources with an effective mode of their reproduction, taking into account the promising interests of the development of the economy and the preservation of human health.

The use of natural resources is irrational when human impact on nature leads to a decline in the strength of its restorative properties, a decrease in the quality and depletion of natural resources, and environmental pollution. It can arise as a result of not only direct, but also indirect effects on nature.

Compliance with the principles of rational nature management will allow developing measures for environmental protection, restoring broken relationships in ecosystems, and preventing the aggravation of environmental situations.
