Description

I

The invention relates to exploratory geology and relates to methods for locating minerals that do not surface.

There is a known method for detecting hidden deposits by drilling boreholes with coring and subsequent chemical or physical analysis.

However, this method requires a lot of time, the use of sophisticated drilling equipment and analysis. for and therefore expensive.

A known method of detecting a field is: minerals (x, including the installation of a sampler on the surface of the Soil, its heating at a sampling point to a temperature that ensures the release into the air of mineral fumes and analysis of air for its C 2 content.

The disadvantage of this method is the limited amount of minerals that can be destroyed, since the evaporation of most minerals requires heating the surface layer to high temperatures.

The purpose of the invention is to increase the economic efficiency of the method.

The goal is achieved by the fact that according to the method of detection of mineral deposits, including sampling from the surface layer of the soil, their analysis and subsequent interpretation of the data obtained, the Irob sampling is made from heat-affected zones, the temperature exceeds 1 point and air dew over these zones.

The method is based on the following.

In the soil surrounding the pipeline, moisture is heated to a temperature above the dew point of air, which causes its evaporation from the surface of the soil. At the same time, minerals dissolved in moisture or their indicator are lifted together with moisture through capillaries from the lower layers of the soil and remain after evaporation of moisture in the surface layer. Over time, the concentration of the mineral or its indicators in the area of thermal influence of the pipeline increases. Typically, the heat-affected zone of the pipeline extends, for example, for trunk gas pipelines to 20 meters in both directions from the pipeline and to 5-7 meters in depth. To detect, for example, ore deposits, the following operations must be performed. Soil samples are taken at a distance of up to 15 m from the pipeline at a depth of 0.2-0.3 m and, for example, spectral analysis of metals is carried out. A high metal concentration indicates where the mineral is located. In the case of a mineralogical analysis, minerals are indicative of indicators, the high concentration of which also indicates the location of the mineral. Increasing (concentration of the mineral or its indicators in the heat-affected zone of pipelines, allows the method to be used to detect weakly developed deposits and at the same time reduces the cost of prospecting by using a simpler technique for analyzing samples; Formula of inventive method of detecting mineral deposits , including sampling from the surface layer of the soil, their analysis and subsequent interpretation of the obtained data, characterized in that, in order to increase the economic efficiency The method's cores, sampling, are derived from heat-affected zones of pipelines whose temperature exceeds the dew point of air above these zones Sources of information taken into account in the examination 1.
