What is the new construction, reconstruction and expansion of coal mines, and the technical transfor

New coal mine refers to the coal mine in the application, according to the submitted geological exploration data, after applying for the relevant mining license, the coal mine starts construction, on this basis in order to complete the scale of the previous design of the coal mine is called a new coal mine. However, if the geological reserves change, in order to give full play to the potential of coal mine construction, the state will not waste the actual existing coal mine resources, and do new exploration data on the basis of the original, so that the coal mine has the geological conditions for capacity expansion. All mines that have been successfully built and mines under construction, as long as the production scale is re-changed, they are considered to be technologically transformed coal mines. The requirements for geological reserves are not the same as those for new coal mines, the new coal mines are one-step coal mines do not need to apply for a new scale, and all the coal mines that have received the mining license and need to re-apply for new certificates are called technical coal mines, in the application process, called technical transformation application coal mines, ** according to the reserve scale of coal mines and local policies for approval, if the approval is passed, it belongs to the approved technical transformation of coal mines, if it does not pass the technical transformation approval, it belongs to the technical transformation on the basis of the new coal mines, However, it does not affect the nature of the coal mine.

In short, all coal mines that have installed mining licenses for the first time are called new coal mines, and all coal mines that have changed the original design plan and need to change the mining license to expand their mining capacity on the basis of the construction of mines that have already started construction are all technical coal mines. At present, there are many small coal mines that carry out technological transformation and expansion on the basis of existing coal mines in Shanxi, Inner Mongolia, Shaanxi, Liaoning, Guizhou and other major coal-producing provinces, and each place has different policies for technological transformation. The state is now working on this.

Not to mention the new construction, the reconstruction and expansion is a transformation project approved on the basis of the original coal mine, and the technical transformation is to carry out the corresponding technical transformation on the original production system.

Coal mine construction refers to the start of coal mine construction after applying for the relevant mining license according to the submitted geological exploration data, so as to complete the scale of the previous design.

Coal mine reconstruction and expansion is a transformation project approved on the basis of the original coal mine, including technical transformation of coal mines and new coal mines. Technological transformation of coal mines refers to the corresponding technical transformation of the original production system to meet the new production needs.

In general, new construction, reconstruction and expansion of coal mines and technological transformation are all aimed at improving the production capacity and efficiency of coal mines to meet market demand.

Legal analysis: The Ministry of Land and Resources and other departments recently issued a notice requiring strict control of the scale of coal mine construction, and in principle, no application for reconstruction and expansion of coal mines shall be allowed within 3 years after the coal mine is put into operation.

The circular demanded that the provincial-level coal mine project approval organs should strictly implement the relevant regulations on project approval and should not exceed their authority in approving coal mine projects. Coal mine construction projects shall be designed and constructed in accordance with the approved construction scale, and the construction and design units shall not expand the production capacity without authorization. In principle, a coal mine construction project shall not apply for reconstruction or expansion within three years after it is handed over for production, nor shall it be expanded through the verification of production capacity.

Legal basis: "Criteria for Determining the Hidden Dangers of Major Coal Mine Accidents" Article 1 In order to accurately identify and eliminate the hidden dangers of major accidents in coal mines, this standard is formulated in accordance with the "Law of the People's Republic of China on Production Safety" and the "Special Provisions on the Prevention of Coal Mine Production Safety Accidents" (Order No. 446) and other laws and administrative regulations.

Hello, coal mine technical transformation project can be classified as a kind of coal mine engineering project. Because coal mine technology transformation projects are usually aimed at improving the production efficiency and safety of coal fiber brothers, improving production destruction processes and equipment, or adopting new technologies and methods for coal mining and processing. These transformation projects can involve the transformation and upgrading of coal mine production lines, the introduction of new equipment and technology, the optimization of existing equipment and technology, etc., these projects need to carry out engineering design, equipment procurement, construction management, project acceptance and other aspects of the work, belonging to the scope of coal mine engineering projects.

Of course, you can't produce, you have to go through the joint trial operation approval, 3 to six months trial production, obtain a coal production license, and a safety production license before production.

It is specially stipulated that production while technological transformation is one of the major hidden dangers in the 15th Five-Year Plan of Violations.

Not producible, consider safety first!

Summary. Hello friends, it's an honor to <>serve you

The problems of coal mine reconstruction and expansion projects mainly include the following aspects: 1During the period of reconstruction and expansion, the validity of the safety production license and mining license of the coal mine may be affected, and it is necessary to change or re-obtain the relevant certificates in a timely manner; 2.

During the period of reconstruction and expansion, it may lead to the imperfection and unreliability of the safety facilities such as the ventilation system, drainage system, and gas extraction system of the coal mine, which need to be constructed and operated in accordance with the design and national regulations; 3.During the period of reconstruction and expansion, it may increase the safety risks of the coal mine, such as flooding, rock burst, and outburst, and effective prevention and control measures need to be taken. 4.During the period of reconstruction and expansion, it is necessary to strictly control the scale and scope of production, avoid over-capacity, over-strength or over-quota organization of production, and avoid over-layer cross-border mining or unauthorized mining (destruction) of safety coal (rock) pillars; 5.

During the period of reconstruction and expansion, it is necessary to strengthen the safety education and management of underground operators to avoid illegal operations and accidents.
