What are the provisions of Article 475 of the Coal Mine Safety Regulations on the use and management

The management and use of miner's lamps shall comply with the following provisions:

1) The total number of good lamps in the mine should be at least 10% more than the total number of people who regularly use the lamps.

2) Mining lamps should be centrally and uniformly managed. Each miner's lamp must be numbered, and the person who regularly uses the miner's lamp must have a special person.

3) The miner's lamp should be kept in good condition, and it is strictly forbidden to issue it when there is battery leakage, insufficient brightness, broken wires, failed lamp locks, poor sealing of the lamp head, loose lamp head ring, broken glass, etc. The miner's lamp should be able to be used normally for at least 11 hours.

4) It is strictly forbidden to disassemble, knock or hit the miner's lamp by personnel using the miner's lamp. After the personnel go out of the well (the ground receives the miner's lamp, after work), the miner's lamp must be returned to the lamp room immediately.

5) Within 2 hours of each shift change, the personnel of the lamp room must report the list of personnel who have not returned the lights to the mine dispatching room.

6) The miner's lamp must be equipped with a reliable short-circuit protection device. High gas mines should be equipped with short-circuit protectors.

Legal analysis: (1) The first electromechanical team shall equip the personnel entering the well with special lamps and special self-rescuers for sliding and annihilation, and the users shall take them up and return them to the shelves. (2) Special lamps and special self-rescuers must be kept clean when they are returned to the shelves.

3) The user receives a special lamp and a special self-rescuer to enter from the north gate of the lamp room, and enters from the south gate when leaving the south gate, and the north gate must walk according to the designated route when leaving the lamp room. (4) During the period when the miner's lamp and self-rescuer are put on the shelf, the first electromechanical team shall carry out maintenance and maintenance. (5) When outsiders need to use miner's lamps and self-rescuers, the mine escort shall be responsible for collecting and returning the mine.

Legal basis: Mineral Resources Law of the People's Republic of China

Article 30 While exploiting the main minerals, the symbiotic and associated minerals with industrial value shall be uniformly planned, comprehensively exploited and utilized to prevent waste; Effective protective measures should be taken to prevent loss and damage to minerals that cannot be comprehensively mined for the time being or that must be mined at the same time and cannot be comprehensively utilized for the time being, as well as tailings containing useful components.

Article 31 The exploitation of mineral resources shall comply with the national regulations on labor safety and health, and shall have the necessary conditions to ensure safe production.

Dear, I'm glad to answer for you. According to your question, you will be provided with the following, for reference only: Article 164 of the "Coal Mine Safety Regulations" "The location where the local ventilator is used for the return type must implement wind power lockout and methane electric lockout, so as to ensure that when the normal operation of the local ventilator stops operation or the wind stops, the power supply of all non-intrinsically safe electrical equipment in the wind shutdown area can be cut off."

When the normal local ventilator fails, when switching to the standby local ventilator to work, the local ventilator shall stop working within the ventilation range and eliminate the fault; Work can be resumed only after troubleshooting and local ventilation is restored to normal operation. If two local ventilators are used to supply air at the same time, both local ventilators must realize wind power lockout and methane electric lockout at the same time. ”

When the coal seam is far away from the surface, it is generally chosen to dig a roadway underground to mine coal, which is an underground coal mine. When the coal seam is very close to the surface, it is generally selected to directly strip the surface soil layer to excavate the coal, which is an open-pit coal mine. The vast majority of coal mines in China belong to underground coal mines.

The scope of the coal mine includes a large area above and below ground, as well as related facilities. Coal mine is a reasonable space excavated by humans when excavating coal-rich geological layers, usually including roadways, shafts, mining faces, etc. Coal is the most important solid fuel and is a type of combustible organic rock.

It is formed by the flourishing plants that grow in a certain geological age, gradually accumulate into a thick layer in a suitable geological environment, and are buried in the bottom of the water or in the sediment, and formed by natural coalification in a long geological age. Among the geological periods in the world, the Carboniferous, Permian, Jurassic and Tertiary strata produce the most coal, which is an important coal-forming age. The carbon content of coal is generally 46 97% and is brown to black in color with a dull to metallic luster.

According to the different degrees of coalification, coal can be divided into four categories: peat, lignite, bituminous coal and anthracite.

Hello kiss Kaiyouxin, I'm honored to answer for you. <>

Article 663 of the Coal Mine Safety Regulations stipulates that special safety technical measures shall be formulated when mining near the grouting area where the wheel has not been consolidated, the abandoned Mochai shaft roadway with silt, and the rock cave.

I hope you will find the following related extensions: It is the area where humans exploit coal resources in coal-rich mining areas, which are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally chosen to dig a roadway underground to mine coal, which is an underground coal mine.

When the coal seam is very close to the surface of the earth, it is generally selected to directly strip the surface soil layer to excavate the coal, which is an open-pit coal mine. The vast majority of coal mines in China belong to underground coal mines. The scope of the coal mine includes a large area above and below ground, as well as related facilities.

Among the geological periods in the world, the Carboniferous, Permian, Jurassic and Tertiary strata produced the most coal in Zhoushan, which was an important coal-forming era. The carbon content of coal is generally 46 97% and is brown to black in color with a dull to metallic luster. According to the different degrees of coalification, coal can be divided into four categories: peat, lignite, bituminous coal and anthracite.

Still have questions? Kiss, can you talk about it specifically? Or is there anything you'd like to talk about? <>
