Problems solved by technology

[0005] From the end of the 1980s to the beginning of the 1990s, China mainly introduced the metallogenic theory and prospecting methods of Central Asia. A large number of drilling operations were deployed in many areas of Northwest and Northeast China, but with little success. Characteristics of metallogenic background conditions in China

Embodiment Construction

[0141] The present invention is attached with some specific implementations from the early stage preparation of the technology until the project results come out.

[0142] 1. Field gravity exploration work; first, the GPS geodetic and gravity measurement team of this project completed the fast static GPS positioning measurement and gravity measurement of four profiles, including the data supplementary measurement of two profiles. Field workload - completed the data collection of 685 gravity measuring points planned and designed, with a completion rate of 154.60%. A total of four gravity profiles of NL line, MD line, E400 line and SH line have been completed. Among them, the total length of the profile is 105.4km, and the total number of physical points is 1172.

[0143] 2. Work progress and data collation; according to the design requirements of the project, gravity measurement work will be carried out between Sunid Right Banner and Erlianhot. Since the accuracy of the measu...

Abstract

The invention discloses an ore prospecting method utilizing ground high-precision gravity measurement. The ore prospecting method mainly comprises six methods, namely a wave number domain iteration method of a potential field high-order derivative, a potential field separation method based on an iterative filtering method, a TASD method for identifying a boundary of a geologic body, an Euler deconvolution method for potential field data processing, a potential field abnormal cross-correlation imaging technical method and a gravity man-machine interaction profile forward modeling method. The ore prospecting method utilizing ground high-precision gravity measurement has the advantages of processing and explaining data of a plurality of gravity profiles, adopting the explaining methods covering the wave number domain derivative iteration method, the iterative filtering method of field separation and the cross-correlation imaging technology based on residual anomalies to be applied to gravity data, and achieves a good processing result.

Description

technical field [0001] The invention relates to an ore prospecting technology, in particular to an ore prospecting method using ground high-precision gravity measurement. Background technique [0002] The ore-forming geological background and conditions of sandstone-type uranium deposits in northern China are quite different from those in foreign countries, so there are also different ideas in the exploration of ore prospecting methods. [0003] Central Asia is rich in interlayer infiltration oxidation zone sandstone-type uranium deposits. The ore-forming model of interlayer oxidation zone deposits mainly comes from here. The sandstone-type uranium deposit metallogenic theory and ore prospecting methods introduced by China's nuclear industry in the late 1980s are mainly based on the previous reference. The successful experience of the Soviet Union in Central Asia. However, the special ore-forming geological conditions in Central Asia are not available in China. For example,...
