What are the steps of mineral exploration? The three phases of mineral exploration

Mineral exploration Mineral exploration is the study of mineral formation and distribution of geological conditions, deposit occurrence law, ore body change characteristics and industrial deposits of the most effective identification and evaluation methods of practical geology, with a strong comprehensive, practical, economic and policy nature, belongs to the category of economic geology, is the comprehensive embodiment of geological science and economic science, the use of geological science, technical science and economic science achievements, directly serve the national economic construction. The main research object is the exploration and evaluation of minerals (or ore deposits), and the main research method is to carry out geological, technical and economic evaluation according to the natural characteristics of mineral deposits, the needs of the national economy and the technical and economic factors of mineral exploration and development. As the main professional course of mineral exploration, it reflects the nature and training objectives of the major.

Geological work to discover minerals and ascertain their quality, quantity and application prospects to meet the needs of national construction. It is also known as mineral resources exploration, mineral deposit exploration, mineral survey and exploration. It belongs to the field of applied geology. It belongs to the field of applied geology.

The task of mineral exploration is to discover and identify industrial ore deposits; for this purpose, it is necessary to use geological mapping, geophysical prospecting, geochemical prospecting methods, drilling and pit exploration and other prospecting methods; to conduct sampling and study the quality of ore; to use industrial indicators to delineate ore bodies and calculate reserves; to study the technical performance of ore beneficiation and the hydrological and engineering geological conditions of ore deposit mining; to make technical and economic evaluation of ore deposits; and to prepare geological exploration reports.

The theory of mineral exploration mainly solves the problem of how to prove the geological data and mineral resources and reserves required to ensure the development and construction of mines with the least input and in the shortest period of time. The main problems related to this are as follows: Mineral resources are buried underground, which is hidden and complex, so mineral exploration is exploratory and risky. The distribution of minerals is controlled by geological conditions and has a certain regularity, so all the work of mineral exploration should be based on geology and guided by geological understanding, so as to reduce investment risks and avoid mistakes.

It is necessary to establish a reasonable survey procedure, carry out the survey work in stages, gradually narrow the scope of the search, screen the objects one by one, and gradually increase the success rate. The current exploration stages in China are divided into mineral survey, detailed mineral investigation and mineral exploration. It is necessary to determine the optimal degree of exploration and capital investment in each exploration stage.

For example, do not waste time by exploring too much high-level reserves in the near future, and waste time by exploring too many high-level reserves; The information required for mine construction must be comprehensively studied and provided to avoid rework or cause mine investment risks; For the objects that have made negative conclusions, the next stage of work will not be continued, and the work can be accelerated for superior exploration objects. It is necessary to pay attention to the comprehensive utilization and comprehensive exploration of minerals, improve the utilization rate of resources, and reduce the waste of investment caused by duplication of work.

Pre-survey, survey, detailed survey, exploration.

The three stages are survey, detailed survey, and exploration. Survey stage: The purpose and task is to carry out the survey work on the discovered ore points and geological, physical and chemical exploration and other anomalies, find out whether there is value for further work, submit the survey report, and generally explore the D E grade reserves, so as to provide a basis for whether to carry out the lead upgrading work in the detailed investigation stage.

Detailed investigation stage: The purpose and task is to evaluate whether the deposit has industrial value after the survey stage work has been confirmed to have further work value, submit a detailed investigation report, and generally explore C D grade reserves.

Exploration Stage: The purpose and task is to explore the ore deposits that have been confirmed to have industrial value after detailed investigation and are intended to be exploited in the near future, and submit an exploration report as the basis for the feasibility study and design of mine construction.

Hello, I have helped you find the result; The procedures that need to be completed after the exploration of mineral resources are as follows:1Application for mineral rights:

The application for mining rights is a prerequisite for mineral mining, and it is necessary to submit an application to the local mineral resources management department, including the application for mining rights, the geological lifting report of the mining area, the mining right evaluation report and other materials. 2.Approval of Mining Rights:

The examination and approval of mining rights refers to the examination and approval of mining rights applications by the local mineral resources management department, including the review of application materials and on-site exploration. 3.Mineral Resources Tax Declaration:

The holder of the mining right needs to declare the mineral resource tax to the national tax department, and the tax rate and payment standard are determined according to the type and output of the mineral. 4.Environmental Shadow is Yu Lao Xiang Evaluation:

Mineral mining has a large impact on the environment, and it is necessary to conduct an environmental impact assessment and obtain the approval of the environmental protection department. 5.Land to make demolition with application:

The holder of the mining right needs to apply for the land use right to the land management department, and generally needs to pay the land use fee. 6.Safety Production License:

Depending on the type of mineral and region, other formalities may need to be submitted, such as soil and water conservation plans, forestry permits, etc. It should be noted that the procedures will vary depending on the region and type of mineral, and the specific situation needs to be handled according to the relevant local regulations.

Include. Mines include coal mines, metal mines, non-metallic mines, building materials mines and chemical mines. Mine size (also known as production capacity) is usually expressed in terms of annual production or daily production.

Annual production is the amount of ore produced by the mine each year. According to the size of the output, it is divided into three types: large, medium, and small. The size of the mine scale should be adapted to the economic and reasonable service life of the mine, and only in this way can the slag save infrastructure costs and reduce costs.

In the process of mine production, mining operations are not only the production link that consumes the most manpower, material resources, occupies the most capital, and has the greatest potential to reduce mining costs. The main way to reduce the cost of mining is to improve labor productivity and product quality, and reduce material consumption.

What kind of ore is divided, it is generally done by physical and chemical exploration to determine the possibility of mineralization. Then go through the planning first, write the area you want to explore into the mineral resource plan, and then go to the blank land to set up a new prospecting right. Apply for prospecting rights and obtain exploration permits.

on practical geological engineering, such as drilling, trenching, pit exploration. Circle ore body, investigate the geological conditions of the hydraulic ring, argue with the general geological exploration unit to solve the sedan car, and finally issue a detailed investigation report, here a detailed investigation of the general situation can be transferred to mining, individual situations such as coal mines need to reach the exploration level. Finally, the prospecting right is transferred to the mining right.

Apply for mining license and safety production license. This is also accompanied by land acquisition procedures, involving forestry, environmental protection, land, and many departments for approval. The process is complex and the cycle is long.

Detail, including what reports are required

The main research object of mineral exploration is the exploration and evaluation of minerals (or deposits), and the main research methods.

It is based on the natural characteristics of the deposit and the technical and economic factors of mineral exploration and development to carry out geological, technical and economic evaluation.

The exploration work is divided into three phases according to GB T 17766: survey, detailed investigation and exploration. In general, it should be carried out in a step-by-step manner. When merging or submitting exploration results across stages, it is also advisable to implement them step by step with reference to the requirements of the exploration stage.
