Recently, Jinhua Municipal People's Government issued the "Jinhua Mineral Resources Planning (2021-2025)" (hereinafter referred to as the "Planning"), which is an important means to implement the national resource security strategy and fulfill the responsibilities of mineral resources management according to law, and an important basis for examining, approving, supervising and managing mineral resources exploration, development and protection activities according to law.
The Plan takes 2020 as the base year, 2025 as the target year, and looks forward to 2035.
The Plan points out that 56 kinds of minerals have been discovered in Jinhua City, and 27 kinds of resources have been proved, mainly non-metallic minerals, and metal and energy minerals are poor. The dominant mineral resources are mainly fluorite, limestone and geothermal.
Limestone is mainly distributed in the Carboniferous-Permian strata of Lanxi and Wucheng, and a small amount of limestone is also produced in Zhuge of Lanxi and Zhongyu of Pujiang. 2. Lingdong of Lanxi is a key limestone mining area in Zhejiang Province, with a large scale and good quality of ore, with an annual output of 6.4 million tons. Among them, limestone for cement and metallurgical flux has resources. 1.
Building stones are all over the country. Mining minerals include tuff, granite, diorite, sandstone, dolomite, limestone, basalt, etc., which are the minerals with the highest degree of development and utilization and the largest consumption. Limited by the protection of ecological environment, there are few areas available for exploitation in the future. Mudstone, shale and sandstone for
brick and tile are highly developed and utilized, and they are produced in Cretaceous continental basins. In recent years, construction waste soil is mostly used for brick making, and the mining volume is sharply reduced. Zeolite and perlite are produced in the Lower Cretaceous strata. The inferred resources of Lingshang Zeolite Mine in Wucheng are 100 million tons; the zeolite mine in Zhongshan, Yongkang is associated with perlite, and the inferred resources of perlite are more than 100 million tons. There is only one kaolin in Pan'an, which is produced in the basalt of Shengxian Formation, with an inferred resource of 1092.
During the 13th Five-Year Plan period, the mining rights of solid minerals in Jinhua City were reduced from 130 to 45, and the mining rights of building stones were reduced from 40 to 21 . To achieve the goal of double control of the number of solid mineral mining rights and the number of building stone mining rights in the 13th Five-Year Plan. The average annual production scale of construction stone mines has increased from 280000 tons to 400000 tons, and the total production scale of limestone mines has expanded to 6.4 million tons. Three new construction stone mining rights were set up, and 102 million tons of stone were put into operation, contributing 1.644 billion yuan in transfer income; Mining 46.6295 million tons of building stone, 14.2882 million tons of cement limestone, 911400 tons of fluorite and 169 tons of geothermal energy.
During the 14th Five-Year Plan period, Jinhua's economy will gradually turn to high-quality development , and the strategies of "two cities" and "nine cities" will be implemented. The demand for mineral resources will continue to be high. It is predicted that the contradiction between supply and demand of building stones will continue to increase, the guarantee capacity of limestone for cement is still insufficient, the supply and demand of fluorite is basically flat, and the demand for geothermal energy is strong. Demand forecast and supply analysis of
building stone. The demand for building stones will reach 2. Based on the production capacity of existing mines, the gap between supply and demand will reach 2. Increasing the investment of sand and gravel mining rights, optimizing the layout of development and utilization, improving the production capacity of existing mines, and promoting the comprehensive development and utilization of mines are the main ways to ensure the supply of sand and gravel in Jinhua City. Demand forecast and supply analysis of limestone for
The Plan clearly States that during the "14th Five-Year Plan" period, the level of mineral resources exploration, development and protection in Jinhua City will be comprehensively improved. Basically find out the geothermal resources and realize the orderly development of geothermal resources. We will promote the concentrated exploitation of sand and gravel, comprehensively promote the utilization of mining land, and create a system of "guaranteeing supply and stabilizing prices" for sand and gravel. Promote the integrated development of limestone, optimize the development structure of fluorite, and improve the support capacity of superior minerals. The structure and scale of mineral development will be more reasonable, and the conservation and intensive use of resources will be more efficient. The level of green mine construction has been upgraded iteratively, and the development of resources and the protection of ecological environment have been more coordinated. Deepening digital empowerment and promoting a new pattern of "overall intellectual governance" in geological and mineral management. New breakthroughs have been made in
investigation, evaluation and exploration. Around the key exploration areas, we will promote the landing of provincial fluorite exploration planning blocks and strive to make breakthroughs in prospecting. Carry out investigation and evaluation of geothermal resources, basically find out the resources, and provide five prospecting targets. To formulate the zoning plan of geothermal resources, scientifically guide geothermal exploration and development, and discover three new geothermal mineral resources. Strengthen the investigation of sand and stone reserve resources, and basically identify the spatial distribution of high-quality building stone minerals available for development and utilization. The ability to guarantee
mineral resources has been greatly improved. Nine centralized sand and gravel mining areas have been laid out, and a number of large-scale construction stone mining rights have been put into operation in an orderly manner, gradually forming an annual mining capacity of more than 40 million tons. We will promote the construction of five sand and gravel industrial parks and build a new pattern for the development of the sand and gravel industry in central Zhejiang. We will urge fluorite mines to reach production capacity, promote the integrated development of limestone mines, promote the conversion of fluorite and geothermal resources to mining, and enhance the ability to guarantee mineral resources. Comprehensive development and utilization of
mining land has been carried out in an all-round way. We will coordinate the comprehensive development and utilization of mineral resources and land resources, promote the comprehensive and coordinated development of resource security, mining land utilization and ecological protection, and give priority to the mining rights of mining land comprehensive development and utilization projects. By 2025, the newly available mining area will reach 1000 mu. The level of
development and utilization structure has been continuously improved. The number of solid mineral mining rights shall not exceed 69, and the number of construction stone mining rights shall not exceed 43. The proportion of large and medium-sized mines is more than 70%, and the proportion of large and medium-sized construction stone mines is more than 80%. Improve the utilization rate of resources in an all-round way, and the "three-rate" level has reached the standard rate of more than 95%. Promote the construction of tail-free and waste-free mines, and the comprehensive utilization rate of tailings and waste rocks is more than 90%. The level of green development of
mining industry has been improved in an all-round way. The completion rate of green mines should be 95%, striving to add 7 new mines into the national green mine list, build 2 green intelligent benchmark mines, synchronously explore the construction of underground and open-pit intelligent mines, promote the pilot construction of 3 township mining green development demonstration zones, and promote the overall improvement of the green development level of mining industry in central Zhejiang.
Digital enabling mining administration has new highlights. We will further promote the "overall intellectual governance" of mineral resources management, improve and perfect the management mechanisms of mineral resources exploration, dynamic supervision and inspection, mining rights management and engineering mining, and initially establish a "digital geological and mineral resources" management system. We should refine the terms of the transfer contract, optimize the business environment, explore common prosperity, promote the transfer of "standard mines" and create "net mine transfer +" in central Zhejiang.
