In the mid-range service market, both large and small service providers will participate, so the competition is more intense. If developers pay attention to technology, security, schedule, management and other factors, they will generally choose large service providers, and if they pay attention to price factors, they will choose small and medium-sized service providers. The mining engineering construction industry follows a strict market access and qualification examination and approval system, and requires corresponding qualification levels. According to the "Qualification Standards for Construction Enterprises" issued by the Ministry of Housing and Urban-Rural Development, the qualification levels of mining engineering construction enterprises are divided into super grade, One grade, two grade and three grade in terms of net assets, professional and technical personnel, management level and completed project performance. Mining project construction enterprises may engage in mining project construction activities within the scope permitted by their qualification levels only after they have passed the qualification examination and obtained the corresponding grade of quality certificates.

2. Development opportunities
First of all, the mining engineering construction general contracting industry is closely related to the macro economy. Although it was dragged down by the financial crisis in Europe and the United States in the past few years, it is currently affected by the new coronavirus epidemic, but China's economic growth trend will not change, and the growth rate of the industry will remain stable. Mineral resources are the foundation of national economic development, and resource shortage has become increasingly prominent in China, and resource security has risen to the national strategy. A series of policy documents issued by the national industry authorities clearly propose to further strengthen the development and integration of non-ferrous metals, gold, iron, phosphorus and other mineral resources and exploration work, and promote the construction of large and medium-sized mine projects.
Secondly, China is still in the industrialization stage, and the economy will continue to grow for a long time. At the same time, China's urbanization process will advance steadily, and fixed asset investment will still be an important endogenous force to pull economic growth. The importance of the mineral industry in the national economy is getting higher and higher, and the sustainable and stable development of the mineral industry provides a broad market space for the owners of the general contract of mining engineering construction. In addition, China's large open pit mining consumption of recoverable resources is very large, every year there are a number of open pit mining enterprises released into the underground mining project bidding information. The market increment of large-scale open-pit mines to underground mining provides new market opportunities for service providers engaged in underground mining.
Finally, China's economy continues to develop, and it is difficult to meet the development needs by relying on domestic resources alone. The state and relevant departments have issued a number of policies to support enterprises to "go global" and support qualified enterprises to mine overseas solely or jointly, so as to enhance the ability to secure resources. It has become an inevitable trend for the mining resources development industry in China that the mining development enterprises and the general contractors of mining engineering construction work together to "go out" to develop overseas resources. At present, many domestic mining enterprises have acquired a number of mineral resources projects in short supply in China overseas, which has driven the general contractor of domestic mining engineering construction to go abroad and obtain the development opportunities of overseas markets.
3. Face challenges
First of all, with the acceleration of economic globalization and the promotion of the national "going out" policy, China's mining development service industry will gradually integrate into the international market, and the proportion of international business will increase year by year. However, compared with the developed countries, the relevant enterprises in China have a big gap in professional technology, business structure, machinery and equipment, financial strength, enterprise scale, market experience and development concept, and are facing greater competitive pressure.
Secondly, the mining operation outsourcing model of the domestic mining development service market is an effective reference to the international "contract mining" model. This new model can give full play to the professional ability of service providers, promote the in-depth integration of both parties, and build long-term cooperative relations; However, due to the short running time of this model in China and the complex composition of the participants in the mine development service market, the operation advantages of this new model can not be fully utilized. In terms of contract execution and mutual trust between the supply and demand sides, further running-in is needed, and similar operating models derived from various types of low-end markets in the industry need to be further standardized.
