Extension of expansion projects!The scale of millions of mining mining mining segments of Jinfeng Sulfa Factory is ensured

A few days ago, Guizhou Jinfeng Mining Co., Ltd. has been reviewed by the expert group in the deep extension and expansion project of the sulfa factory ditch and mining section of the sulfa factory (30 meters to -250 meters), and was reviewed by the Guizhou Provincial Department of Emergency Management.

The underground mines of Jinfeng Company consist of the two independent mining production systems of the sulfa factory ditch and the redundant semi -mining section. After years of production and mining, the resources of the redundant semi -mining section are close to the end. The extension of the sulfa factory ditch and mining section (205 meters to 30 meters) passed the completion acceptance and obtained a safety production license in February this year. In order to avoid the sharp decline in production capacity and supplement the production capacity of mining as soon as possible, the extension project below 30 elevations of the sulfur plant ditch section is imminent.

In order to ensure the continuous and stable mining production capacity, under the high attention of the company's leadership, in July 2021, the Jinfeng mining technology and safety team actively cooperated with the Changchun Gold Design Institute to start the deep extension project of the sulfa factory ditch and mining section (Phase II) Security Facilities design. After the Spring Festival in 2022, the initial design of the project passed the review of CICC Gold Co., Ltd., and the safety facilities were completed in May this year. During the period, the Jinfeng team actively cooperated with the careful design of the design institute, and optimized the design solution in combination with the actual production of the on -site production to ensure the quality of the safety facility design plan.

The design is designed for the deep extension of the sulfa factory ditch section (30 meters to -250 meters), with a total investment of nearly 200 million yuan. The design continues to adopt the slope development method. The two -wing diagonal ventilation scheme and the relay drainage system are delayed to fill the hierarchy in the hierarchy to fill the mining method. Under the premise of ensuring safety, make full use of existing large underground mobile devices, and continue to give play to the advantages of mechanized mining for deep mining production. After the project infrastructure is over, the sulfa factory ditch section can provide an annual production capacity of 500,000 tons below 30 meters. scale.

On May 30, the expert group listened to the reporting of the design and establishment of the sulfur factory ditch and mining section expansion project (30 meters to -250 meters). In other ways, the design of the depth of the sulfur pitch and mining section was inspected and reviewed in detail.

At the expert review meeting, the expert group believed that the expansion project of the sulfur factory ditch section of the Jinfeng Company (30 meters to -250 meters) safety facilities, reliable safety facilities, and production safety system settings complied with safety standards and "metal non-metal mines Safety Regulations GB16423-202 "and other relevant regulations, unanimously agreed to pass the review, and required the project construction to be accepted in a timely manner after the specifications were completed.

Gao Rong, Secretary of the Party Committee and Chairman of the Jinfeng Company, said that in the next step, the company will continue to carry forward the work style of "do it right away, do the real work", and actively accelerate Promote the construction of the project, and at the same time, the construction and construction of the "Safety Facilities" are strictly carried out, and the safety management of the construction site is strengthened to ensure the safety of construction site operations, continuously consolidate the essential safety and compliance production and operation capabilities of the enterprise, and make further promoting the high -quality development of enterprises to promote the development of high -quality development of enterprises New contribution.
