Problems solved by technology

[0002] At present, the method of geological prospecting for metal ore and oil and gas mines usually adopts the geoelectric extraction method, which is to set sampling points on the soil in the prospecting area, set electrodes at the sampling points, and pass 220V high-voltage electricity for 48 hours to extract the minerals in the soil. Element information, and then sampling for laboratory analysis, according to the data of laboratory analysis, and then drilling for prospecting, this method of prospecting is costly, has many interference factors, and has low accuracy

Embodiment Construction

[0020] The present invention carries out ore prospecting effect tests on more than ten known deposits such as Kangjiawan lead-zinc-gold-silver mine, Dachang tin mine and Dahongshan copper mine in my country, all of which have obtained very good verification effects. Utilize the present invention to carry out prospecting in Tongling mining area, and drill. The specific implementation steps are as follows:

[0021] According to the point distance of 20 meters, the B-layer soil at a depth of 0.6 meters was collected, and processed into 18 samples larger than 120 meshes. In the room, 20 grams of the samples were weighed and put into an electric adsorption container, and a chlorobenzene solution with a pH value of 4.5 was used as a sample. Auxiliary, use nitrofoam as the adsorption medium, insert the platinum electrode, power on, after 4 hours of electro-adsorption, take out the adsorbent, incinerate and dissolve, and use atomic absorption test, the result is abnormal in the east o...

Abstract

The present invention discloses a method for discovering metallic mine and oil-gas field by using electric adsorption process. Said method includes the following steps: placing the collected sample into electric adsorption instrument, adding adjuvant and absorption medium, then inserting electrode into the interior of adsorption instrument and energizing said electrode with direct current to make electric adsorption, extracting mine-forming element and accompanying element which are transferred to ground surface from deep ore body band and adsorbed by soil under the epigenetic geochemical action, then analyzing and testing these element components, utilizing computer to make electric adsorption abnormal graph, according to the abnormal graph utilizing abnormal mode to make comprehensive judgement to define the positions of ore body and dead body. Said method is simple, low in cost and high in working efficiency.

Description

(1) Technical field: [0001] The invention relates to an ore prospecting method, in particular to an electric adsorption ore prospecting method suitable for metal ore and oil and gas mines. (two) background technology: [0002] At present, the method of geological prospecting for metal ore and oil and gas mines usually adopts the geoelectric extraction method, which is to set sampling points on the soil in the prospecting area, set electrodes at the sampling points, and pass 220V high-voltage electricity for 48 hours to extract the minerals in the soil. Elemental information, and then sampling for laboratory analysis, according to the data of laboratory analysis, and then drilling for prospecting, this method of prospecting is costly, has many interference factors, and has low accuracy. (3) Contents of the invention: [0003] The purpose of the present invention is to provide a fast, low cost, high work efficiency, large detection depth, less interference factors, suitable ...
