What is the difference between metallic non metallic mines and non coal mines

There is no difference, but the name is different, it used to be called a non-coal mine, and now it is called a metal and non-metal mine, which seems to be more standardized.

There are 91 kinds of non-metallic minerals, mainly diamond, graphite, autosulfur, pyrite, crystal, corundum, kyanite, sparkite, andalusite, wollastonite, sodium saltpeter, talc, asbestos, blue asbestos, mica, feldspar, garnet, pyrophyllite, diopside, tremolite, vermiculite, zeolite, alumite, miscanite, gypsum, barite, poison barite, natural alkali, calcite, glacial stone, magnesite, fluorite, gemstone, jade, agate, limestone, chalk, etc. <

Coal mines do not belong to the metal industry, they belong to the extractive industry. If it is a filling industry, coal mining is an extractive industry. If you fill in the major, it depends on what major you are engaged in, and you don't need to consider the factors of coal mining, such as secretarial, engineering technology, business management, etc.

The extractive industry is the basic industry of the national economy, and 93% of China's energy, 80% of industrial raw materials, and 70% of agricultural production materials come from extractive products. The development of the extractive industry has provided rich mineral raw materials for various sectors and has played a supporting role in the development of the national economy.

Introduction to Extractive Industries

The extractive industry is an industrial sector that directly extracts various raw materials and fuels from nature, mainly including the mining and dressing of various metal and non-metal minerals (such as coal, iron ore, oil and gas, chemical ores, etc.), timber harvesting and tap water production.

Its characteristics are: 1. The natural substances in nature are the objects of labor, and its products are the necessary raw materials for the manufacturing industry.

2. The construction period is long, the investment is large, and the product transportation volume is large.

3. The finite nature of mineral deposit resources. The development of extractive industries must consider their resources, reserves, grades, occurrence conditions and distribution, the degree of national urgency, and the geographical location of transportation, so as to determine their reasonable exploitation scale, life and development sequence.

Classification of industry status

There are three main categories: oil and gas exploitation, coal exploitation, and mineral exploitation.

Coal mining methods

There are many types of coal mining methods, and the coal mining methods used by the world's major coal-producing countries are generally divided into two categories: wall type and column type. These two different types of coal mining methods are very different from each other in terms of coal mining system and mining process.

According to different mine geology and technical conditions, there can be different coal mining systems and coal mining processes to cooperate, thus constituting a variety of coal mining methods. For example, under different geological and technical conditions, longwall coal mining, pillar coal mining or other coal mining methods can be used, and the longwall and pillar coal mining methods are very different in terms of coal mining system and coal mining technology.

It can be considered that the coal mining method is composed of two parts: the coal mining process and the layout of the mining roadway.

Hello, according to the information query display. Coal mine cover is not a non-metallic mine. Metallic and non-metallic mines refer to all mining enterprises except coal mines, coal-measure pyrites, symbiotic and associated mines with coal, and petroleum mines.

Non-coal mines refer to mining enterprises that mine metal ores, beams, leaks, radioactive ores, petrochemical raw materials, building materials, auxiliary raw materials, refractory materials, and other non-metallic minerals (except coal). Non-coal mines are free of gas hazards, but are not fundamentally different from coal mines in other respects.

Non-coal mines refer to mines and tailings ponds that mine metal ores, radioactive ores, petrochemical raw materials, building materials, auxiliary raw materials, refractory materials and other non-metallic minerals (except coal). Although non-coal mines do not pose a gas hazard, they are not fundamentally different from coal mines in other respects. Due to the variety of ore body conditions, there are three main types of mining methods in non-coal mines: empty field, filling and caving.

Hello, glad to answer for you. <>

Non-coal mines: Non-coal mines refer to mines and tailings ponds that mine metal ores, radioactive ores, petrochemical raw materials, building materials, auxiliary raw materials, refractory materials and other non-metallic minerals (except coal). Although non-coal mines do not pose a risk of gas, they are not fundamentally different from coal mines in other aspects.

In general, it belongs to the mining industry, the resource industry, and to be specific, it can also be directly said that it is not a coal mining industry. Hidden Zen school.
