Manual implementation of extraction management and management
use the mineral as a building material

Minerals made in our country are very rich, distributed across much of the territory of the country: sand, gravel, gravel, flax, clay, limestone, construction sites, decorative tiles ...

Due to its natural distribution and all over the country, mining for the construction material of the country has long been available, these types of mining products have been actively contributing to the construction of the country. In addition to the positive side that meet consumer demand, there is indiscriminate mining, unauthorized use of mineral resources that cause a huge waste of resources. Many have invested in rampant mining, lack of planning and a unified plan that leads to a difficult state of ease. In mining, the regulations of exploitation, safety regulations, the use of explosive materials ... are not respected and performed well. Many fatal accidents have occurred, ensuring the environmental environment of the mining facilities is weak.

To seriously enforce the implementation of the "ordinance of mineral resources" and the development of the exploitation management situation, the use of mineral resources as a building material in the entire section of the manual constructs the management of mining and the use of mineral resources. the mineral as the construction material is as follows:

I. GENERAL REGULATION

1. The mining management of mineral resources as a building material across the country must fully approve the state laws that have enacted on management, exploration, exploitation, mineral resources; right under the right of planning and joint development plans of the country. Construction and construction of construction materials.

2. The mined mineral must use the right purpose of being approved.

3. Mining must follow the right of the approved mining design method and the radical use of the resource.

4. Make sure the environment, environment and labor safety. When the extraction must be returned to use for the next purpose.

II. STATE MANAGEMENT OF MINERAL RESOURCES

1. The geologic investigation is that the work must be conducted in advance as a scientific base for the work to exploit all the construction of the methods or the project of geological exploration of the specialized body. The project, the project, must determine the goal, the content, and the level of rational research that has an economic, technical, high quality, and practical efficiency. The authority to approve or evaluate the census report stipulated at paragraph 3 Article 14 of the mineral resource ordinance.

2. The Ministry of Construction is the organization of strategic construction, planning, long-term planning, and short term planning, drafting the development policies of the manufacturing materials for building materials. Proposals for specific regulations on the management of mineral resource protection as construction materials and the economic regulation of mining engineering economics as construction materials.

The Ministry of Construction is the basis for the review of technical economics and testing the mining design of mineral deposits as the construction material of the management prior to the State Department.

Based on the development of the industry, the construction department helped the Provincial People's Committee to review the economic economic treatises and to browse the mining design of mineral deposits as the construction material inscribed in Section 3 Article 14 of Decree 95-HSBT on 25 March 1992.

For the mines as the construction of the other Central Ministry of Central Management, when the ministry, the presiding industry review of the mining review must have the Department of Construction being the official commissioner of the review review board if the mine is large, or is used. a written agreement by the Ministry of Construction before the review of the testimony if the bill is small.

III. ABOUT MINING.

1. After a license to exploit the mine and register the mining sector at the state agency with jurisdiction under Article 15 Decree 95-HSBT on 25 March 1992, the mining design was established. The exploitation of mineral resources as construction materials is done in accordance with the construction of the construction materials industry to protect the country's mineral resources.

2. Before the mining of mineral resources as construction materials in the exposed mines would have to do well-built basic construction in the mine such as the summit, making roads, cutting floors, cutting off, creating floors, and building manufacturing items in accordance with the design. All right.

3. Mining necessarily on the floor or stage, ensuring high performance and safety for the impulses, transport. Under technical conditions, they may be able to exploit wells and use transportation. Absolute not to exploit a frog function. For deposits of small production, manual exploitation is a suitable small layer.

Here. high or deep positions to ensure the safety of the worker up to the floor in the production process necessarily make the way to the rank.

Mining under the water must ensure no yoke or change of flow; it does not destroy the annual accrets of the floodplains, not causing landslides affecting nearby processes; not polluing many of the living waters of the population.

4. For the mineral deposits of large reserves, but the demand for mining in front of the eyes is not much, producing only as a small bill, as well as the process of exploitation, as well as the process of unimpediable use when switching to major mining.

For mineral resources as rare building materials such as asbestos, insects, natural pigments, when mining has to be responsible for all of that mineral resource.

5. All the mines that exploit the land, stone as a building material must strictly conduct a safety of the safety of both the exploitation, transport and use of explosive materials.

Construction of stone building or other resources as a building material by a mine-explosive drill must have an explosive passport. An explosive passport must be approved by the director of the factory.

IV. SPECIFIC REGULATIONS FOR SOME OF THE MINERAL RESOURCES AS CONSTRUCTION MATERIALS ARE USED.

1. decorative stones

Mining of blocks from sedimentary rocks, metamorphants, magnids, aphits to make stone ornamacal beyond hydraulic separation methods, crafts, should apply advanced technology techniques to cut large blocks according to regulatory extraction design.

Decorative stone mining is not used in the method of detonation, in the case of an economic thesis that allows only detonators, detonators, and detonators. Deposits of heavy rock that need to be removed are also able to drill down small mines, but to avoid the phenomena that cause the rock to consider the solution of the soil, it is necessary to remove the soil, and it must be determined to allow the height of the class to be located in the middle of the ground. A fresh stone

The open-drilling passport for the access class must be approved by the factory engineering board and the director of the browsing technique.

Depending on the structure of the lava class, the mining engineering board decides whether to layer between the access layer and the fresh rock. If you see the need to have a buffer, the layer thickness is required. Hey. 0.1m for all kinds of lava. The buffer method needs to be conducted by mechanical or manual methods and only to exploit the newly developed buffer.

2. Stone built

The mineral is allowed to exploit the construction stone to comply with the safety of the TCVN 5178-90.

Here. Stone deposits built if there are other useful minerals to accompany (or lie in the upper mantle) during the extraction of the main mineral, there is a need for the extraction of mineral products.

The production facility must regularly test the physical properties, contamination of contamination, product flatness. During the construction of the construction stone must regularly adjust and develop the machine's features, ensuring that the space shuttle controls, on the other hand, against debris under the size of the product.

3. Shinto, sand

Gravel products mined from terrestrial or underwater mines must ensure adequate quality as built stone products. If there is a coating that must be removed first, the product must be clean, must remove the impushable impushones and must be classified in accordance with the right rules.

Sand mining in the terrestrial or underwater quarry is also subject to article 2 of this text in terms of government exploitation, which must be able to ensure the right to be clean and the product of the product.

Here. The mines that make up both the pavement and the gravel and the gravel and the sand, and the sand that they exploit must take advantage of both kinds of materials, which are not yet to take advantage of it, are not prevented from being exploited.

Sand or gravel fields are formed in the form of lenses and are large in depth when mining must have anti-mudslides and the extraction method must proceed in horizontal layer.

White sand in a highly valued form of resource is the primary ingredient for producing glass of the type and some of the required addits. When mining of white sand must be selected, the classification follows the standard of chemical composition and the composition of the body by means of recruiting for each type of mine. No white sand is available for use in the standard industry, used in the construction of a warrant and other normal employment.

4. St and flax

Organizations and individuals when delivered and allowed to exploit the clay, the flax as construction materials must fully comply with regulations at Articles 45, 46 and 48 land laws. If we exploit the clay to make the tile tile to comply with the provisions of the L/LB/TT on 1-8-1992. When mining must take advantage of the first layer of lightning, the flax or the extraction to the maximum depth that the technique uses. No small lava mining causes a lot of resources and resources. The case of either the lightning or the flax under the water performs as the two-item III has specified.

Depending on the product of the products and the construction of the clay and the flax is used to produce materials that build the base into the chemical composition and their physical properties during the extraction process must be used to ensure the correct quality. quantity, the regulation of sale to consumers such as Decision 255 /BXD-VLXD issued on the quality of construction materials built on 15 -10-1989.

V. PROTECT AND USE RESOURCE RATIONAL

1. mineral resources used as construction materials of various types. Thus, in the course of the extraction of every individual organization, it has to apply the appropriate scientific measures to exploit with the rational sense of use for each mineral resource as a building material. Highly valued mineral resources such as limestone to make cement, white sand has a SiO content. ₂ High levels of oxygen and low oxygen levels for the production of glass, glass, clay, and clay. ₂ O. ₃ High for the production of construction ceramics and marble building materials and granitomas with great monolithic height, all individual organizations are not exploited in arbitrary use of waste. These mineral resources are only mined using the approved evidence material.

2. In the field of mineral resource processing technology as construction materials must ensure the high recovery of raw materials and the accompanying raw materials using a synthesis of the synthesis of mineral resources as the construction material when mining includes both the mineral resources. The scrap of the mine.

3. Mineralogical resources that do not yet exploit, or in the exploitation of the minerals that accompany or are poor minerals that have not been well protected.

The highly valued mining case is the construction material that the type of building material is standard of using only the same type of mineral, but in the near production where there is no production, it must take into account economic efficiency. It is made and has to be granted a specialized jurisdiction to be used.

VI. THE ORGANIZATION.

1. This information is in effect since the date of signing and applying unity in the country to all units, individuals are Vietnamese citizens as well as organizations and individuals who are foreigners when conducting mineral mining as building materials.

The organization, the individual when conducting mining and the use of minerals as a building material must fully enforce the existing state texts, must study and perform the full terms of this information.

2. The provinces, cities and the Construction Department are tasked with sending a six-month recurring report on the Ministry of Construction by the content:

The production of products and products has been processed for six months and all year.

The rate of product recovery for the year.

Manufacturing technology changes (if available)

The consumption and economic efficiency of the mining and processing facilities are based on the ./.
