Research on the development and utilization situation and governance measures of sand and stone resources in Chongqing City

Based on statistical data and existing research, this paper systematically analyses the current situation of development and utilization of sand and stone resources in Chongqing City, including the planning layout, mine distribution, production and price trends, supply and demand security, and summarizes the problems of development and utilization. It has been discovered that: ① the supply of river sand has significantly decreased, and the trend of limestone mine reduction and scale development has strengthened, and the production of sand and stone has increased, which has become the main source of sand and stone supply guarantee. Due to the economic growth pressure, property market downturn and other factors, the prices of sand and stone show a declining trend. ② Due to the resource endowment, topography and geography, control conditions, production and processing level and other factors, there is uneven development of the area, the scale level is not high, the actual production capacity is not enough to put, sand and stone quality stability is not high, the project sand and stone disposal supervision and management difficulties and other problems. In order to effectively serve the economic and social development and industrial needs, and to develop and utilize sand and stone resources with higher quality, countermeasures and proposals have been put forward. These countermeasures include building a spatial system for the coordinated development of mega, large, medium and small mines, promoting the optimization of the development and utilization structure and the coordinated development of the region; actively promoting the transfer of “net mines”, the mines that have been put into the classification of policy, and actively supporting the release of effective production capacity; strengthen the upstream and downstream convergence and departmental supervision, and promote the quality of sand and stone improvement; coordinate the establishment of a protection list system for major engineering projects to stabilize the supply of sand and stone, and strengthen the supervision and management of sand and stone for construction projects.
