1. How to deal with the difficult use of mineral resources in the ** dynamic incentive plan in February?
According to the "new classification standard", the remaining mineral resources of closed pit mines are mineral resources that are still difficult to use, and there are no resources and reserves, but in order to retain the original mineral resource information, the original resource type before the closure is counted separately. If the construction project overlays important mineral resources, it shall be classified according to the type of original resources when compiling the compaction assessment report. After the approval of the overlying mineral resources of the construction project, they should be counted separately as mineral resources that are still difficult to use. If there are resources within the scope of mining rights that cannot be expected to be economically exploited, such as large burial depths, complex mining technical conditions, refractory smelting and coal resources with sulfur content of more than 3%, etc., when applying for the review and filing of mineral resource reserves, the relevant chapters of the report shall describe the geological characteristics of such resources, but the resource reserve estimation chapter shall not separately submit the quantity of such resources, and the resource reserve estimation scope shall not include the occurrence scope of such resources.
2. Are all kinds of protected mine (coal) pillars and ground damage still difficult to utilize mineral resources? Who will define?
Situations in which the mineral resources are lost by design but are not still difficult to utilize include: surface structures (structures) such as roads, railways, high-voltage transmission lines, oil and gas transmission pipelines, towns, cultural monuments, villages, etc., as well as protected mine (coal) pillars such as rivers and reservoirs; The amount of coal pillars protected by coal mine faults, waterproofing, well field boundaries, industrial sites, main roadways in the shaft, etc., and the amount of coal pillars on all sides of the open-pit coal mine and the coal pillar of the river; The amount of ore that needs to be set up to protect the pillars of metal and non-metallic mines, open-pit stopes, industrial sites, shafts, etc. The above-mentioned mine (coal) column volume should be ultimately defined by a pre-feasibility study, feasibility study or preliminary mine design. When submitting the report on mineral resource reserves, if only a brief study of mineral exploration is carried out, it should also be based on the actual measurement of "roads, railways, high-voltage transmission lines, oil and gas transmission pipelines, towns, cultural monuments, villages and other ground buildings (structures), as well as rivers, reservoirs, water sources" and other facts, standardize the estimation of overlying resources, and include them in the total resources, but need to be separately statistically explained. When drawing an overlapping map of the estimated scope of resource reserves and the scope of mining rights, the extent of the fact overlay should be marked in the map.
3. How to define mineral resources that are still difficult to utilize?
Mineral resources that are still difficult to utilize refer to the identified mineral resources that cannot meet the development needs of mining, processing and metallurgy, infrastructure, economic market, law, environment, community or policy conditions at present and in the foreseeable future. It is still difficult to utilize mineral resources, which are not expressed in terms of resources. It is not expected that the low grade of economic mining (including low-grade ore buried deep, complex mining technical conditions, refractory smelting resources, raw coal sulfur content of more than 3% coal resources, are still difficult to use mineral resources, should be reasonably defined through industrial index demonstration and rough research, approved construction projects overlay important mineral resources, policy closure, closed pit mine residual mineral resources according to the documents issued by relevant departments, define mineral resources that are still difficult to use.
