Problems solved by technology

This data processing method only considers the average value of the original data The simple linear relationship between the standard deviation S and the standard deviation S ignores the spatial change characteristics or correlation of the data itself, and cannot effectively reflect the spatially related geological phenomena.
The method is relatively rough and theoretically flawed

Embodiment Construction

[0043] The present invention will be described in further detail below in conjunction with accompanying drawings and examples.

[0044] Taking the Naren area in the central part of the Erlian Basin as an example,

[0045] Such as Figure 1-Figure 4 Shown, the present invention provides a kind of sandstone type uranium ore soil radon data processing method, and this method comprises the following steps:

[0046] Through the measurement of soil radon in the Naren area in the middle of the Erlian Basin, the project layout is 100m in point distance and 500m in line distance, and a total of 1485 raw data of soil radon gas measurement points have been obtained.

[0047] Step 1. Data correction

[0048] Step 1.1. In the coordinate system with the No. 9 (L10-9) point on Line 10 as the origin of the coordinates, in the four quadrants and two coordinate axes, select a measuring point closest to the origin, a total of 8 measuring points ; Table 1 is a schematic diagram of data distrib...

Abstract

The invention belongs to the technical field of sandstone type uranium ore prospecting, and particularly relates to a sandstone type uranium ore soil radon data processing method. The sandstone type uranium ore soil radon data processing method comprises the following steps of: step 1, correcting data; step 2, processing the data; step 3, determining an anomaly threshold; and step 4, drawing a soil radon gas isoanomalic contour map according to the anomaly threshold. According to the sandstone type uranium ore soil radon data processing method, components with spatial self-similarity are highlighted or geologic phenomena related to space are reflected, and the influence of non-natural or environmental factors on the soil radon gas observation value is eliminated, so that the delineated soil radon anomaly better conforms to the geological law, and the sandstone type uranium ore soil radon data processing method is more precise.

Description

technical field [0001] The invention belongs to the technical field of sandstone-type uranium ore prospecting, and in particular relates to a data processing method for sandstone-type uranium ore soil radon. Background technique [0002] Radon is mainly manifested as a non-polar monatomic molecule. It is a colorless, tasteless, and odorless radioactive inert gas. It generally does not participate in chemical reactions, which makes it have a strong diffusion ability. Radon in nature mainly comes from the decay of radium, and radium has an inseparable relationship with uranium. Sandstone-type uranium deposits have been paid more and more attention because of their large reserves, easy mining and low environmental burden. Due to the good permeability of sandstone-type uranium deposits, the radon gas produced by its decay can be well distributed in the soil around the ore body. The distribution characteristics of underground sandstone-type uranium mineralization can be well re...
