Description

Technical Field

[0001] The invention relates to sampling device technology, in particular to a portable sampling device for geological and mineral exploration. Background Art

[0002] Geological and mineral exploration refers to a series of work to investigate, explore and evaluate the mineral resources on the earth. Its purpose is to determine the type, distribution, reserves and grade of mineral resources, and to provide scientific basis and technical support for mineral development. The main purpose of geological and mineral exploration sampling is to obtain information and data about geological and mineral resources to support mineral exploration and development decisions. The following are several main purposes of geological and mineral exploration sampling:

[0003] Determine the existence and distribution of minerals: Sampling and analysis can be used to determine the existence and distribution of mineral resources. Different types of mineral exploration sampling can provide information on the mineral composition, element content, grade, etc. in rocks, soils, water bodies and ores, thereby determining the potential value and scale of mineral resources;

[0004] Evaluate the potential of mineral resources: Data obtained through exploration sampling can be used to evaluate and predict mineral resources. By analyzing the sampling results, including the geochemical characteristics of rocks, soils and water bodies, the formation mechanism, enrichment rules and reserve potential of the ore deposits can be inferred, providing clues and guidance for subsequent exploration work;

[0005] Feasibility assessment of mineral resource development: Exploration sampling can provide information on the nature and characteristics of the ore body, such as ore grade, ore type, ore structure, etc. This information is crucial for the feasibility assessment of mineral resource development and helps determine factors such as mining methods, process flow and economic feasibility;

[0006] Environmental impact assessment: Exploration sampling can also be used to assess the impact of mineral exploration and development activities on the environment. By analyzing the chemical composition of soil, water and rocks, we can understand the potential impact of mineral exploration activities on the surrounding environment and take corresponding environmental protection measures;

[0007] Scientific research and academic exchanges: Exploration sampling can not only be used for industrial purposes, but also provide important samples and data for research in the fields of geology and earth sciences. These samples can be used to study geological processes, structural evolution, mineralogical characteristics and other aspects, promote the accumulation of scientific knowledge and academic exchanges. Through geological and mineral exploration sampling, comprehensive and accurate geological and mineral information can be obtained, providing a scientific basis and decision-making support for the rational development and utilization of mineral resources.

[0008] Impurities in the soil sampled for geological and mineral exploration may interfere with the exploration results. The main hazards are as follows:

[0009] Error: Impurities in the soil may interfere with the determination of target elements, resulting in errors in the analysis results;

[0010] Low: The moisture content, organic matter, etc. in the soil may cause the concentration of the target element in the sample to be low;

[0011] Interference: Mineral particles, rock fragments, oxides, etc. in the soil may form compounds with the target elements, resulting in deviations in the analysis results;

[0012] Pollution: The soil may contain pollutants such as heavy metals and organic pollutants, which may have a significant impact on the accuracy of exploration sampling and environmental impact;

[0013] All of the above factors may lead to inaccurate exploration results, and may even affect the evaluation and development decisions of mineral resources, causing serious impact on mineral exploration work. Therefore, when taking samples for geological and mineral exploration, appropriate sample treatment measures must be taken to reduce or eliminate the interference of these impurities. At the same time, possible interference factors must also be considered and corrected during the analysis process to obtain accurate exploration results.

[0014] The impurities that may exist in the soil sampled for geological and mineral exploration mainly include the following:

[0015] Organic matter: Soil may contain various organic substances, such as plant residues, animal feces, etc. These organic substances may interfere with the determination of target elements during the analysis process, so care should be taken during sampling and analysis;

[0016] Mineral particles and rock fragments: Mineral particles and rock fragments of different sizes often exist in the soil. These particles and fragments may contain components unrelated to the target elements and may interfere with the exploration results;

[0017] Oxides: Oxides, such as silicon dioxide and iron oxide, are often found in soil. These oxides may form compounds with the target elements, leading to deviations in the analysis results.

[0018] Heavy metals and other pollutants: The soil may contain some pollutants, such as heavy metals (such as lead, mercury, cadmium, etc.), organic pollutants, etc. These pollutants will have a significant impact on the accuracy of exploration sampling and environmental impact.

[0019] When the existing sampling devices for geological and mineral exploration are used, the impurities in the sampled soil are not screened and processed. These impurities may lead to inaccurate exploration results and even affect the evaluation and development decisions of mineral resources, causing serious impact on mineral exploration work; and in order to reduce unnecessary errors and deviations and improve the accuracy and reliability of data when sampling in the field, the samplers will inevitably take multiple samples. When encountering a place where the car cannot drive in and the sampling can only be done on foot, the samplers need to carry multiple samples. If the samples contain a large amount of impurities, it will increase the physical burden of the samplers and affect the sampling progress and sampling quality of the samplers; and the existing sampling devices for geological and mineral exploration are not easy to collect the samples obtained, which will increase the sampling time of the samplers and reduce the sampling efficiency.
