Embodiment Construction

[0055] The present invention is described in further detail below in conjunction with embodiment.

[0056] A method for detecting paleochannel uranium deposits, the method comprising the following steps:

[0057] (1) According to the distribution position of the ancient river channel in the study area, four "Feng"-shaped seismic survey lines are laid out

[0058] The principle of seismic survey line deployment: According to the distribution position of the paleo-channel in the study area, three parallel survey lines are laid out. Contact seismic survey line, contact seismic survey line is perpendicular to the main survey line, the contact seismic survey line and the three main survey lines are in the shape of "Feng", and the contact seismic survey line is used to contact the contact seismic survey line of the three main seismic survey lines .

[0059] (2) Arrange geophones, excitation sources and seismographs on the four "Feng"-shaped seismic survey lines in the above steps ...

Abstract

The invention belongs to a method for detecting a uranium mine, and specifically discloses a method for detecting a paleochannel type uranium mine. The method includes: four seismic lines in the shape of a Chinese character "feng" are laid; the seismic lines in the shape of the Chinese character "feng" are provided with detectors, an excitation source, and a seismograph; the excitation source is started, seismic vibration signals are generated, and the seismograph is turned on to observe seismic amplitude data received by the detectors; seismic data processing of seismic original single-shot data is performed; seismic data stratigraphic interpretation of seismic result data C is made, and stratigraphic data D is obtained; standardization processing of sound wave data and density data in a research region is performed, and the sound wave data SON_standard and the density data DEN_standard after standardization are obtained; according to C, D, SON_standardj, and DEN_standardj, wave impedance data volume [omega]res is obtained by employing jason inversion software and an inversion method based on a model; and according to the wave impedance data volume [omega]s, preferable mineralization areas of the paleochannel type uranium mine on the four seismic lines are determined. According to the method, the mineralization environment of the paleochannel type uranium mine can be rapidly, economically, and effectively detected.

Description

technical field [0001] The invention relates to a method for detecting uranium ore, in particular to a method for detecting ore-forming environment of paleochannel type uranium ore. Background technique [0002] Paleochannel uranium deposits are an important type of uranium deposits. The formation of this type of uranium deposits is controlled by the paleo-ore-forming environment such as stratum lithology and structure, so it is difficult to detect. In the past, there were not many methods to detect the ore-forming environment of paleochannel-type uranium deposits, and the overall effect was not good. The drilling method was relatively expensive and inefficient; the detection accuracy of the electromagnetic prospecting method was low, and it was difficult to find out the ore-forming environment of this type of uranium deposits. ; The detection depth of the seismic imaging method is shallow, and the interpretation results are greatly affected by personal experience.
