The potential value of new mineral deposits in Hunan is 500 billion yuan

The potential value of new mineral deposits in Hunan is 500 billion yuan Nearly 50 newly discovered mineral sites have been discovered. The potential economic reserves of the discovered reserves have reached 500 billion yuan; the world-class lead-zinc mine base has been identified in the Huayuan-Fenghuang area of ​​western Hunan, and the unique Tin Tin prospecting model has been created... This is A “Transcript Sheet” submitted by Hunan Provincial Bureau of Geology and Minerals in the past three years.

Recently, the reporter learned from an interview with the Bureau that in the past three years, the Bureau has seized the favorable opportunity of the country’s full implementation of ore-breaking breakthrough strategic actions, led by geological prospecting, and adhered to the principle of “big geology, great service, and great development”. The concept of work, in accordance with the "geological work of the Bureau, the strong development of industry, harmonious construction and development" plan and advance the work, the overall geological work and reform and development has made considerable progress.

A major breakthrough has been made in geological prospecting. In recent years, the Bureau has undertaken 110 national financial geology projects, ranking first in the five provinces of Central South China; 280 provincial-level fiscal geological projects, accounting for 70% of the total number of such projects; and are important at the national level in Nanling, Qinhang and Xiangxi. Nearly 50 mineral deposits have been newly discovered in the metallogenic belt, and a number of reserves of coal, tungsten, tin, lead, zinc, gold, manganese, antimony, iron and copper resources have been discovered. The potential economic value amounts to 500 billion yuan; in the Huayuan-Phoenix area Proved the world-class lead-zinc mine base, the Huangshaping and Dongpo old mines have been highly commended by Premier Li Keqiang for the prospecting results of the old mines in Huangshaping and Dongpo, and they have discovered a super-large tin-tungsten polymetallic deposit in Xiling, Chaling, and have created unique characteristics. Tinfield model."

The exploration and development of new energy and clean energy started well. Through the work in recent years, the Bureau has basically ascertained the status of geothermal resources in the province and found a number of medium- and large-scale geothermal fields in Changsha, Zhangzhou and Yueyang, and conducted shallow geothermal energy in important cities such as Changde, Changsha and Zhuzhou. The development demonstration has systematically carried out the investigation and evaluation of shale gas in Hunan, and the shale gas survey in important basins. In cooperation with Hualing, it has obtained the exploration right of shale gas in the Longshan block.

At the same time, the pace of "going out" has accelerated and preliminary results have been achieved. The Bureau has established cooperative exploration and development relations with large-scale central enterprises such as China Minmetals and China Electric Power, Hualing Group and Chenzhou Mining, etc. In 14 provinces (regions) such as Xinjiang, Inner Mongolia, Qinghai, and Yunnan, Southeast Asia and South America Twelve countries in Africa and other regions have conducted ore prospecting work and undertaken more than 70 projects outside the province and abroad. A number of overseas exploration and development bases for gold, copper and iron have been initially established in Cambodia, Myanmar, Brazil, and Australia.

Geological services have achieved significant results. In the past three years, the Bureau has completed 20,000 square kilometers of large-scale regional geological surveys and geophysical geochemical explorations; the province’s mineral resources potential assessment, mining rights verification, and mineral resources status survey have also been completed on schedule, and the province’s Mineral resources have been developed; more than 1,500 mines have been surveyed for their geological environment, more than 100 major disasters have been prevented, and major water shortages and water-seeking projects in urban areas have been actively implemented to solve the problem of drinking water for more than 500,000 farmers. Changsha, Six cities including Zhuzhou, Xiangtan, Yueyang, Changde, and Yiyang provided a batch of emergency water sources; identified 80,000 square kilometers of soil and water quality in the Dongting Lake and Xiangjiang River basins, and used Hunan Province to declare control of heavy metal pollution in the Xiangjiang River Basin. The direct basis provided by major projects; the geological survey and zoning of the urban agglomeration of Changsha, Zhuzhou and Xiangtan was basically completed, and the underground three-dimensional geological structure was initially established, which provided a geological basis for the construction of the “two-type” society in Changsha, Zhuzhou and Xiangtan; and the completion of the Changsha Metro, Changsha International Finance Center, Shenzhen University, Shenzhen, Aiken Ditch and Azhai Bridge and other major projects of engineering investigation and construction, security It has impeded the engineering safety of major infrastructure construction in the country and Hunan.

The development of geological prospecting reforms has made important progress. The Bureau’s geotechnical survey economy has maintained a growth rate of more than 20% for three consecutive years, the total economic revenue has doubled, the total global assets have doubled, and the industrial structure has been further optimized, basically forming geological surveys, engineering surveys, prevention and control of geological disasters, surveying and mapping Multi-polar and multi-polar support for large geological industrial systems such as geographic information engineering, land consolidation, basic construction, and engineering inspection; the management foundation has been consolidated, and three new mechanisms for investment, employment, and distribution have been established and improved; A group of high, precise and pointed equipment represented by human aircraft has been put into use. Core drilling, geophysical exploration, surveying and mapping technologies are at the advanced level in the country, and the integration of mineral exploration technology in the Nanling area has won the second prize for national science and technology progress; Continuously improving, the average income of employees on the job has maintained a growth rate of over 12% for three consecutive years, the retirement pension has been secured, the families of the disabled workers have been effectively rescued, and the geological exploration culture has developed and flourished. On the basis of carrying forward the fine tradition of "Sanguangrong", Formed the "science, innovation, dedication and harmony" of Hunan's geological prospecting core value body .

The Bureau Director Ye Aibin said in an interview with reporters that he will strive to reuse a period of 5 to 8 years to form a strategic replacement of important mineral resources such as coal, lead, zinc, tungsten, tin, iron, manganese, gold, copper and shale gas. Base; More active geology services for Hunan's “two-type” society construction; Scientifically plan the reform and development of the geological survey system, Accelerate the pace of industrial economic development, Promote the reform of institutional mechanisms, Focus on upgrading the ore prospecting ability and level , Effectively safeguard and improve people's livelihood, develop and prosper Hunan Geological Survey Culture, build a strong main force for geological work with strong prospecting ability, high service level and excellent working style, and make new contributions to building a well-off society in an all-round way and fulfilling the Chinese Dream.

Proper Application of PDC bit

1. When designing the PDC bit hydraulic parameters, the pump pressure must be greater than 13.0 MPa, using equal or approximate diameter.

2. Due to the poor impact resistance of diamond, the upper and lower drilling rigs cannot touch hard objects, and there must be no falling objects in the well. It is strictly forbidden to drill and dig.

3. It is strictly forbidden to press down when the drill is blocked. Should be connected the Square Drill Pipe to open the pump stroke, but it should not exceed 30 meters Large section ream .

When drilling down to the last two single roots, the joint drill pipe is flushed to the bottom of the well and the circulation is large, and the bottom of the well is circulated clean. Then use a small drill pressure, low speed drilling 0.5 meters, the bottom hole shape.

4. Normal drilling is the preferred drilling parameter. The drilling pressure is 30~60KN and the speed is 217~117 r/min. For every 250~300 meters, a halfway trip must be made.

5. It is not allowed to use PDC bit in the gravel layer and soft and hard staggered formations, and drill when there is falling object at the bottom of the well.

6. It`s good effect in large sections of homogeneous soft to medium hard formations .
