Application Case Introduction

1. Concept and positioning

Adhering to the concept of "green and sustainable, life community", the company has gradually formed the core competitiveness of mine ecological restoration and soil restoration of "germplasm resources + ecological big data". Main location services The following main contents:
 To solve the government's urgent needs of the government, help solve the main problems of environmental degradation and ecological degradation in mining areas, so as to achieve the status of maintenance free, self-restoration and self-maintenance; how to use the environmental governance fund reasonably and compliant.

Help mining enterprises to build green mines, and provide whole-process consultation and guidance for the construction of mining industry, including the rational use of environmental governance funds, the management of the surrounding environment of mining enterprises, and the improvement of scientific research ability and achievements of mining enterprises. And how to extend the industrial chain in the process of green mine construction, adjust and upgrade the consultation of mining enterprises.

At the same time, we will actively extend to the comprehensive land improvement of the whole region, make efforts in the comprehensive improvement of farmland and desertification control, supporting related industries, and invigorate, do well and strengthen the land industry.

2. Current situation of mine ecological restoration

 At present, the mine ecological restoration is still in the traditional restoration mode, which is basically based on land reclamation. The restoration method adopted is simple and crude, and simple green restoration. When the mine ecological restoration project is completed, the vegetation is easy to degrade, resulting in a single plant variety and disharmony with the surrounding environment.

After the use of the mining enterprise ecological management fund, there is no other additional income. Just do "clear waters and green mountains", did not turn "clear waters and green mountains" into "gold and silver mountains".

3. Difficulty of mine ecological restoration

(1) The problem of landform remodeling mainly refers to the elimination of potential disasters and adapting to the surrounding natural terrain.

(2) The problem of soil reconstruction, mainly for the damaged soil reconstruction in the mining area, taking engineering measures and physical, chemical and biological methods to reconstruct a soil profile suitable for plant growth, improve the productivity of reconstructed soil in a relatively short time, and improve the environmental quality of reconstructed soil.

(3) The re-establishment of water system mainly includes the improvement of water interception and drainage system and making full use of the topographic characteristics of geomorphic remodeling. The precipitation will be diverted in a reasonable and orderly manner, and the excess precipitation will be collected and utilized.

(4) The difficulty of vegetation reconstruction is mainly on the basis of landform reconstruction and soil reconstruction, according to different land damage types and degrees of the mine, combining the local climate, superior construction plants, altitude, slope, slope and effective soil thickness, and configure other advantageous plants. Through reasonable planting and management, the restored plants will naturally evolve, and finally form a sustainable and stable plant community.

(5) The difficulty of "clear water and green mountains" becoming "gold and silver mountains". At present, in the construction process of "clear water and green mountains" of mining enterprises, most of them only have input and no output. There is an overall problem of greater pressure. How to truly transform the "clear waters and green mountains" into "gold and silver mountains" through the adjustment, integration and upgrading of the industrial model.

4. Pain point of mine ecological restoration

(1) Lack of systematic, holistic and insufficient understanding of the ecological restoration of mines leads to high cost of restoration and unsustainable ecological restoration.

(2) One mine, one plan, one mine and one measure, leading to no fixed repair measures. At the same time, the promotion and application of new technology is insufficient, the technology innovation is not enough, and the technology renewal cycle is long.

(3) There is no clear planning goal for land use after restoration, and there is no unified standard and specification for restoration.

(4) The overall economic chain of mining enterprises is relatively fragile, and the ability to resist risks is relatively weak. How to extend the industrial chain and increase the anti-risk economic unit. How to combine the local industrial advantages, make reasonable planning and design, form a regional industrial advantage cluster, increase the income of enterprises.

5. Advantages and scientific research ability of Mongolia grass

 We focus on mine restoration and environmental governance. The company has a Research Institute of Mine Restoration, gathering domestic and foreign mine restoration experts, to provide customers with systematic mine restoration, environmental governance, and industrial upgrading solutions, from planning and design to product technology research and development, and then to engineering construction.

(1) A perfect mine ecological restoration technology system, and a standardized restoration system integrating design, planning, construction and maintenance.

(2) Mine ecological big data platform navigation, accurate repair, and appropriate medicine.

(3) Domestic data and scale of the leading local plant germplasm bank.

(4) Mature construction team and construction technology.

(5) Perfect research and development system, a strong scientific research team.

(6) Mature consultant and planning and design team.

In the past 20 years, a total of 38.68 million square meters of mines and slopes have been restored, with a project output value of nearly 2 billion yuan.

 In the continuous exploration in the field of ecological restoration and scientific research, the mature technologies are gradually solidified and stabilized.

At present, the company has applied for 75 patents, 24 authorized patents, including 5 invention patents and 19 utility models. It has undertaken one major project of the autonomous region, one major project of Ordos, and two transformation of scientific and technological achievements. Serving 2 scientific research projects of mining enterprises. Responsible the preparation of 2 local standards and 2 group standards.
