Problems solved by technology

Alkaline granite-type uranium deposits are one of the important types of uranium resources in the world. However, due to the constraints of dressing and smelting technology, the research on this type of uranium deposits in my country is still relatively weak.
There are few studies on 3D fine modeling methods for alkaline granite-type uranium deposits
[0003] In addition, the existing modeling methods for ore deposits are generally "cubic" three-dimensional modeling, which can only highlight the core main body. The real boundary of the ore deposit is often based on reasonable speculation, and it is an overall model, and the module has not been realized. change

Embodiment Construction

[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0049] A modularized three-dimensional fine modeling method for alkaline granitic uranium deposits provided by the present invention specifically includes the following steps:

[0050] Step (1): Build a surface elevation module based on topographic measurement.

[0051] Taking the ore deposit as the center, carry out topographic survey within the scope of the ore deposit, and provide basic data for the construction of the surface elevation module. The measurement accuracy is 1:2000, the data acquisition line distance is 20m, and the point distance is 5m. Using RTK-GPS on-site collection, data processing using CASS software. The elevation control survey selects the GPS fitting elevation, and all coordinate records should maintain the same coordinate system. Import the collected data into Arcgis software to generate a topographic map with a c...

Description

technical field [0001] The invention belongs to the field of geological prospecting of uranium deposits, and in particular relates to a three-dimensional fine modeling method of alkaline granite type uranium deposits. Background technique [0002] The construction of ore deposit model is an important link in geological exploration activities, and its visualization characteristics play an important guiding role in guiding the deployment of further exploration work. Different types of deposits have different geological characteristics, and the parameters and modeling steps required in the modeling process are also different. Alkaline granite-type uranium deposits are one of the important types of uranium resources in the world. However, due to the constraints of dressing and smelting technology, the research on this type of uranium deposits in my country is still relatively weak. There are few studies on 3D fine modeling methods for alkaline granite-type uranium deposits. ...
