General Secretary Jiang Zemin pointed out in the report of the 15th National Congress of the Communist Party of China: "China is a country with a large population and relatively insufficient resources. It must implement a sustainable development strategy in its modernization drive." How to rationally develop and utilize mineral resources, effectively protect the ecological environment, and maintain The sustainable development of the mining industry is a major issue facing the current mining development.

Due to historical reasons, there are some vague understandings in the society. It is inevitable that mining development will be a waste of resources, which will inevitably result in waste of resources. The negative effects of mining development on the environment will inevitably bring humanity The destruction and deterioration of the ecological environment, and believe that under the current economic conditions, it is very difficult to cure this big problem. However, after more than 30 years of hard work, the Dalin sand people have not only destroyed the ecological environment, but have effectively improved the harsh environment.
Inner Mongolia Dalin Sand Group Co., Ltd. (formerly Inner Mongolia Dalin Sand Plant) was founded in 1965. It is the first domestic hydraulic sand selection plant invested by the First Ministry of Machinery Industry to solve the foundry sand of Changchun No. 1 Automobile Manufacturing Plant. Later it was placed under the jurisdiction of Tongliao City, Inner Mongolia. The company is located 2.5 kilometers southeast of Dalin Town, Tongliao City. The mining area is 15.75 square kilometers. The reserves of silica sand resources are abundant. At the end of 1998, the recoverable reserves amounted to 4736 million tons.
For more than 30 years, the company has undergone technological renovation and transformation, and its production capacity has been continuously enhanced. It has increased from 800,000 tons/year in the initial period of construction to 300,000 tons/year. The variety of products has been increasing from the original single washing sand. It has developed into six major varieties of washed sand, scrub sand, selected sand, floating sand, and standard sand special sand. The product quality enjoys high reputation in the international and domestic markets. Washed sand is rated as a superior product, scrub sand, and selected sand. as the district preferable products, and won the national industry competitions, "Golden tripod Award"; Zhejiang to expand the sales market days, the Changchun first automobile Works has increased from one development to 28 provinces, municipalities and autonomous regions of more than 300 large and medium enterprises And some colleges and universities. The mining method has also evolved from a single primitive method in the past to the mining method of sand mining vessels and the realization of pipeline transportation. Inner Mongolia Dalin Sand Group Co., Ltd. has become a leader in the same industry in China.
Over the years, with the support of the municipal party committee and the government and the strong support of the land and mining administrative departments, we have focused on protecting the ecological environment while carrying out land reclamation, implementing scientific mining, unified planning, and rational mining while strengthening production management. Improve the beneficiation process, scientific selection, and maximize the availability of resources. Through reclaiming greening, the ecological environment has been improved, and the organic integration of resource efficiency, ecological benefit, economic benefit and social benefit has been realized.
First, the main measures and methods
At the beginning of the plant construction, the wind and sand disasters here were more serious. The plant area and its surrounding areas were bare and flowing sand dunes, and there were no plants. The entire mining area was an infinite desert. The water loss is serious. Every time it is windy, it is dark and dark, the sand is full of sky, the ecological environment is extremely bad, and the sand dunes move to the northeast at a certain speed every year. This not only causes a lot of sand resources to be lost, large grassland and good fields are deserted, but also directly Dalin threat to farmland via the railway lines and north. In response to this situation, the company (formerly Dalin Sand Plant) led a group of people to go deep into the actual situation, conduct on-the-spot reconnaissance of the entire mining area, and through careful investigation and analysis, everyone agreed that in order to effectively use and protect resources, it is necessary to scientifically run mines. Let the sands be cured and let the sand settle in place. In the development of mineral resources, we must make overall plans and rational planning. The combination of mining development and land remediation, mining development combined with wind and sand fixation, timely planting and reclamation of the already-harvested area, can no longer expand the desertification area, use 10 years to control the mobile sand dunes, and strive to make the desert change by the end of the century. Become an oasis. The big policy has been set, and the Dalin sand people began to challenge the desert. First of all, in the urgent need to manage the land, planting trees around the dunes. Every time the afforestation season, all the cadres, employees and family members of the company go all out to plant trees. Due to the harsh environment, the survival rate of planting trees is particularly low, and some planted in the first year. In the second year, it was not killed by sandstorms, it was exhausted by drought, and the survival rate was very low. But we are not discouraged, do not compromise, use our brains and think of ways. In the upper wind, branches and wooden stakes are used to form a wind protection fence, and the wells are regularly watered, so that the survival rate is greatly improved, and the sand sea begins to appear green. Although the company’s leadership has changed a few, the governance plan for remediation and replanting has not changed, and the momentum has not decreased. While we are planting trees, we pay special attention to the management of forest trees. In order to better protect the trees, the company set up a full-time forestry team consisting of 8 people, responsible for the people, and the care and management of the forest land. [next]
In the 1990s, especially in the past five years, the company's leaders paid more attention to the land reclamation and environmental protection work, and effectively regarded land reclamation and environmental protection as a major event for the benefit of future generations. A leading group for comprehensive management, land reclamation and environmental protection planning led by the company's leaders was set up. The office was set up to be responsible for daily work, and supervisors were supervised and inspected. According to local conditions, land reclamation and environmental protection plans and medium- and long-term development plans will be formulated in a timely manner, and large-scale reforestation and land reclamation projects will be started, and the single reforestation model of the past will be changed. The soil left by the beneficiation is used to cover the mined surface. After the sand is covered by the soil, the farmer's fertilizer is applied. The soil is used to build the field and the pit is developed into a fish pond. By the end of 1998, the soil will be rebuilt and the fish pond will be developed. The three cumulative investments of replanting and planting trees amounted to more than 600,000 yuan, and the accumulated investment in the protection of the wind and sand to control the ecological environment has reached more than 800,000 yuan.
Second, the main results and results
For more than 30 years, the company has organized production, while sand-fixing and afforestation to control the environment. Rehabilitation and control of the ecological environment have invested a lot of manpower, material resources and financial resources every year, especially in recent years, large-scale reforestation and land reclamation. Greening and planting trees have completely changed the face of the yellow sands that have been in the past, showing the tree-lined shelterbelts, the farmland, the fish ponds and the forests that can’t be seen at the margin. A variety of wild animals have been settled here to achieve an organic unity of resource, ecological, economic and social benefits.
By the end of 1998, 240 mu of land had been rehabilitated, including 100 mu of paddy fields, 140 mu of water-irrigated farmland, more than 300 kg of rice per mu, and more than 400 kg of corn per mu. The 240 acres of farmland can be irrigated by the cycle of sand washing, and the two incomes can reach more than 40,000 yuan per year. The freshwater fish culture surface reaches 30 mu, and the annual income is only 20,000 yuan. More than 8,000 mu of afforestation, including more than 3,000 mu of replanting trees, more than 2,000 mu of forests in reforestation, more than 3 million yuan of forestry output, and more than 90% of the area of ​​reclamation.
Third, the future development vision
In the future development of mineral resources, the company will continue to do a good job in land reclamation and environmental protection work, and strive to achieve a piece of mining and reintegration. It is planned to plant 2,000 mu of trees in the year 2000 (including 200 mu of farmland shelterbelt), and the total planting green area will reach 100,000 mu. At the same time, the planting species will be increased, and the coniferous cypress trees will be gradually increased from a single broad-leaved poplar. In order to reduce the cost of afforestation, the company built a nursery, cultivated seedlings, continued to renovate the land, and re-created 260 acres of land, including 100 acres of paddy fields, and the total reclamation area reached 500 acres; 20 acres of fish ponds were redeveloped, and the fish surface reached 50. mu. By 2005, the reforestation and tree planting area will reach 12,000 mu, and the land will be rebuilt to 100 mu. At the same time, the high-yield fields will be transformed into medium and low-yield fields, and the fish surface will be 150 mu. The rice fields will be raised to raise fish, and at the same time, ducks will be raised and raised. Pigs, etc., take the road of sustainable development.
