China News Agency, Beijing, March 27 (Reporter Zhou Rui) China's National Development and Reform Commission issued a news on the 27th that the agency, in conjunction with the Ministry of Natural Resources and other departments, issued a "Guiding Opinion on Promoting the Healthy and Orderly Development of the Sand and Gravel Industry"
Sandstone is the most basic and indispensable building material in engineering construction. Construction sand is divided into natural sand and machine sand. Among them, natural sand includes river sand, land sand, and sea sand, and machine sand is sand and gravel made by mechanical crushing.
In the past, the use of natural sand and gravel in China was mainly derived from mountains and rivers. With the depletion of natural sand and gravel resources, increasing ecological protection requirements, and continuous increase in demand for construction projects, machined sand gradually replaced natural sand to make up for market demand. At present, the sandstone of the mechanism has accounted for about 70% of the sandstone used in construction.
The relevant person in charge of the Price Division of the National Development and Reform Commission pointed out that in recent years, the amount of sand from major rivers in China has fallen sharply, and the number of sand and gravel enterprises has decreased significantly. At the same time as the project construction cost, it affects the construction progress of the project and brings hidden dangers to quality and safety.
The "Guiding Opinions" issued this time have clearly put forward a series of measures around the promotion of scientific use of mechanism sand, river sand, sea sand and alternative sand sources.
The first is to promote the high-quality development of the mechanism sand and gravel industry. This includes vigorously developing and promoting the application of mechanism sand, optimizing the development and distribution of mechanism sand, accelerating the formation of high-quality production capacity of mechanism sand, and reducing transportation costs.
The second is to strengthen the comprehensive regulation and utilization of river sand. This includes strengthening the comprehensive management of illegal sand mining, rationally developing and utilizing river sand resources, increasing the use of dredged sand in river channels, and exploring the use of silt sand in the Three Gorges Reservoir area.
The third is to gradually promote the orderly exploitation of sea sand. Including the reasonable exploitation of sea sand resources, the establishment and improvement of a long-term mechanism for the management of sea sand mining; strict regulation of sea sand use, and strict implementation of sea sand use standards.
The fourth is to actively promote the alternative utilization of sand sources. This includes supporting the comprehensive utilization of waste rock tailings, encouraging the use of solid waste resources for the production of recycled sand and gravel, promoting the overall use of sand and gravel for engineering construction, and actively promoting the assembly of steel structure buildings.
The Guiding Opinions emphasize that at present, under the premise of scientifically preventing and controlling the new crown pneumonia epidemic, and in accordance with the orderly resumption and resumption of production of engineering projects, it is necessary to effectively ensure that the supply and price of the sand and gravel market are basically stable.
