Description
Technical Field
The invention belongs to an ore prospecting technical method for an ultra-large type precious metal uranium nonferrous metal rare metal ore deposit, and particularly relates to an ore prospecting method for efficiently, quickly and effectively searching the ultra-large type gold, tungsten, copper and nonferrous metal rare metal ore deposit by comprehensively researching, evaluating and analyzing a former geological background, various geological mineral products and materialization remote data and combining with ore prospecting practice experience and the like by utilizing the technical method means of latest geology, mineralization theory, materialization remote detection and the like.
Background
It is well known that various minerals are distributed very unevenly in the world. The world's oversized deposits are mainly concentrated on the zona pelagica, the Teti zone, the two crustal giant active zones, and the four ancient stabilized Daclaton in south Africa, Australia, Russia and America, and some of the larger ancient parcel margins or deep fracture zones. Not totally 90% of the total amount of mineral resources in the world, such as precious, uranium, non-ferrous and rare metals, diamond, geothermal, etc., comes from deposits distributed in these areas. In recent years, Jiangxi, Ganxiang and Dongpen tungsten-copper mine found to change the distribution pattern of tungsten mine in Jiangxi province and even the world. Increasing tungsten metal content (WO) 3 ) 597 ten thousand tons, which is equivalent to the newly added 124 large tungsten ores. Approximately 57% of the total amount of tungsten resources in the world. And for example, in the area of about 2000 square kilometers of the area of the nanometer biyas Wako Mongolia, dozens of oversize uranium ores are concentrated, the resource amount exceeds 100 ten thousand tons, and the uranium ore resource amount (U) which occupies the world can be recovered (less than $ 130/kg) 3 O 8 ) 30 percent. And 1637 copper ores with a total amount of more than one thousand tons in the world, wherein the amount of the large-ultra large copper ore (the amount of copper is more than 500 million tons) at the position of the bed 116 is only 7.1 percent of the total amount, the resource amount accounts for 71.2 percent, the amount of the ultra large copper ore (more than 2000 million tons) accounts for 1.5 percent of the total amount at the position of 24 (9 in Chilean), and the resource amount accounts for 40 percent of the total amount. Also, although there are nearly two to thirty types of gold ores, controlling the amount of 50% gold metal is a hillside belt type (green rock zone) and karlin type gold deposit.
The development of the oversize deposit is of great significance to the economic development of a country. For example, the discovery and development of the Jiangxi Dexing ultra-large copper mine, the Jiangxi copper industry group company is the only continuous ultra-2000 million yuan production value enterprise in the last five years in the Jiangxi, and is always ranked at about 355 th in 500-st world. The total value of Jiangxi copper industry group company in 2019 is close to 3000 billion yuan, and if the value of the product of the Jiangxi copper industry group company is 5000 billion, the total value of the product of the mining, smelting and extending industries of the Jiangxi copper mine accounts for 1/5 of the Jiangxi province. The international geophysical and geodetic society of the last ninety years has been an important topic of research on ultra-large deposits as solid geosciences.
The national academy of sciences in 1992 initiated a climbing program hosted by the lucent fielders-project "basic research related to ultra-large deposits" category a-30. Then, the systematic study of the mineral formation of the super-large mineral deposit in China is a party of Parry and Rich universities. No report is found on an evaluation system of an ore prospecting technical method related to large-scale ultra-large precious metal nonferrous metal rare metal ore deposits at home and abroad up to now.
Because the distribution of the ultra-large precious metal nonferrous metal rare metal ore deposit in the earth shallow layer is not uniform, the cause is various, the ultra-large precious metal nonferrous metal rare metal ore deposit formed by a simple single layer or a single geological body, such as sand shale type copper ore and uranium ore, is not in the discussion range, the invention mainly discusses the more complex exploration work of the ultra-large precious metal nonferrous metal rare metal ore deposit related to the rock magma. The evaluation of large-scale non-metallic ore and medium-large ore deposit of the same type as the ore species related to the magma hydrothermal solution still has reference value.
Disclosure of Invention
The invention aims to provide an ore prospecting method for an extra-large type gold, uranium, tungsten and copper nonferrous rare metal ore deposit.
The invention aims to realize the following technical scheme, and the method for prospecting the ore deposit of the extra-large type gold, uranium, tungsten and copper non-ferrous rare metal is characterized in that: taking modern mining theory and practice as guidance, firstly fully utilizing previous data and practical experience, deeply researching geological background, mining characteristics and secondary development 'physical, chemical and remote' multiple abnormal information of a mining zone, and delineating a beneficial section of a mining or a possible existing spatial position of a mining body from large to small and from face to point, wherein the specific implementation mode comprises the following steps:
step 1: finding knots in the zone, finding the nodes of the superposed mineral forming elements, namely a field (a mineral concentration zone), in the existing mineral zone or a new mineral zone divided according to the mineral forming conditions, comprehensively analyzing multiple elements such as geological, mineral, geophysical prospecting, chemical prospecting and remote sensing data in the mineral zone with a scale of 1: 20-50 ten thousand, wherein the multiple elements are closely related to the mineral forming, such as stratum, magma, structure, geophysical prospecting and chemical prospecting, and the like, in the mineral zone, and the field or the mineral concentration zone, such as gold, tungsten, copper and the like, closely related to deep fracture can be formed at the nodes of the complete or superposed mineral forming elements;
step 2: on the nodes overlapped by the mineral forming elements, further analyzing, reducing the mineral finding range, searching for the optimal points, namely mineral deposits, and analyzing the favorable mineral forming structure positions in the area, the favorable surrounding rocks, the lithologic times and the lithologic combinations in the area through the systematic research and analysis of typical mineral deposits in the area from the possible geological structure, the mineral forming rock mass and the node range favorable to the development of the surrounding rocks by the fine research of geological, mineral product, geophysical prospecting, remote sensing data and the latest scientific research results in the middle and large 1: 5-20 ten thousand scale area, finding out the mineral-containing construction, and delineating the optimal mineral forming points, namely the positions of the development of the mineral deposits, in the nodes;
and step 3: finding a body in a point, finding an ore body in a defined ore deposit position, carrying out fine research on geological, mineral products, geophysical prospecting, chemical prospecting and remote sensing data of an ore region with a proportion scale of 1: 2000-10000, analyzing possible structure positions of the ore body in the ore region and deep hidden mineral forming rock mass space characteristics from possible ore containing and mineral guiding structures and favorable surrounding rock alteration characteristics through research and analysis of occurrence forms and scales of typical ore deposit ore bodies in the region, carrying out deep geophysical prospecting data inversion, analyzing possible structure positions of the ore body in the ore region and deep hidden mineral forming rock mass space characteristics, analyzing vertical zonation and multi-position integral characteristic vacancy prediction of a target ore species through a deep prospecting profile surrounding rock alteration zone, and finding the ore body in the optimal ore controlling ore containing structure and mineral forming rock mass position. And the size and occurrence state of the ore body are estimated to predict the resource amount.
The invention provides an ore-finding exploration technical method evaluation system of an ultra-large precious metal uranium nonferrous metal rare metal ore deposit by combining various ore-forming prediction methods and deep detection technology, three-dimensional modeling and big data development in recent years in the process of summarizing ore-finding experiences in China (mainly Jiangxi province) and south Africa, Nanbia, Iran, Congo (gold), Australia, Canada, Peru and the like in nearly 20 years. Reference is mainly made to more than 800 medium-large mineral deposits at home and abroad and to near 1000 medium-large mineral deposit data which are read in various documents or introduced for more detailed description. The evaluation system is open, has prominent key and clear target, is different from the division of predecessors, does not exclude the recognition and reasonable utilization of predecessors, and focuses more on the procedures of the ore-finding step. The method has the advantages of great significance, novel content, practicability and feasibility, is easy to understand and operate, and also has scientific popularization significance. Has great significance for shortening the period of finding the mine, reducing the risk, saving the cost and improving the success rate of finding the mine.
The main content is as follows: one main line is to search large ores and good-benefit ores, and a 'three-three' method is proposed and is shown in figure 1. The first three are three branches of the super-huge ore deposit, namely, the advanced ore-forming theory, the excellent technical management and the effective technical method are used for realizing the large ore finding, and the three aspects are important preconditions or basic prerequisite elements for finding the super-huge ore deposit. Not to be taken to be specific
The theory of ore formation and the technical method means are mainly how to use. The advanced mineralization theory comprises the division and understanding of mineralization zones, new understanding of mineralization processes, material sources, mineralization structures, mineralization event confirmation, various mineralization prediction methods and theories, new ore deposit type discovery and the like. The excellent technical management refers to general project demonstration, design review, project supervision, expert consultation, follow-up visit in the middle of projects, consultation of important problems and the like, and particularly, the suggestion of experts familiar with project mining areas is very important. The breakthrough of finding the mine is often achieved by combining new knowledge or innovation of single aspect in the three aspects. The breakthrough of finding the mine is often achieved by combining new knowledge or innovation of single aspect in the three aspects. Such as: the Jiangxi geological exploration fund center management team finds and determines the tungsten ore of the Jiangxi great lake in the first tungsten ore deposit in the world and the tungsten ore of the Jiangxi xi province which are found and explored by the geological teams of Jiangxi, northwest and 916 in the Ganxi province and the geological research institute in the Jiangxi province in 5 years, the biggest black tungsten ore deposit in the Jiangning Dongshen world which is researched by the geological survey research institute in the Jiangxi province, the first wollastonite ore deposit in the Xinyu bamboo mountain world, and the metal reserves of the Happy Valley white granite uranium ore deposit which are found and sought by the Ming-Shi Min in the Nanbiya (nucleus verification) are mainly achieved by innovation of technical management or breakthrough of ore-forming recognition.
And the second step of finding oversize ore, the initial step is in-zone finding, the forward step is in-zone finding, the target step is in-zone finding, and a complete ore-finding exploration technical method evaluation system is formed. The method not only accords with the process that the geology and the ore finding rule are recognized from shallow to deep and gradually from thick to thin, but also accords with the steps and procedures that people carry out exploration work in one area, and overcomes the interleaving or contradiction and inconvenient use caused by the division and discussion of the geology and the ore forming zone of one area from one side by different experts and scholars. In most cases the cause of the deposit that has been found or exploited is not yet in the future, and the fact that it is the most urgent to find the deposit, especially to the first place of the new or foreign country where the job is to first sign on the right or the best place, the research can be done simultaneously or later. For example, in many divisions of the mineral formation zones, theoretical research is very correct from the perspective of mineral formation time and space, namely, the mineral formation region → the first-level mineral formation zone → the second-level mineral formation zone → the third-level mineral formation zone, and the like, but the authors accept unintentional refusal, but the use is inconvenient, and in most cases, the mineral formation zone is determined only when more minerals are found in one area. Therefore, the author proposes to find the knot in the belt, the point in the knot and the body in the point, and the image is visual and has hierarchy.
The initial layer step is a zone-in-zone finding junction, namely, geological and materialized remote information data (mainly with a medium-small scale) of geological and materialized remote information of a comprehensive analysis region, latest results and the like, various resource potential evaluation methods including a fuzzy mathematic method, a specialist method, large data processing and the like are fully utilized, and abnormal zones, gradient change zones or regions with deep fracture and rock mass development regions can be found from the edges or deep fracture zones of possible ancient Kraton, two huge tectonic zones and ancient plots, so that a mineral finding junction is identified and determined, namely, the junction is found from the mineral forming zone, namely, a mineral concentration region (a mineral field).
The forward step is to find points in the junction, namely large-scale geological and materialization remote data in the further analysis of the range of the junction or the ore accumulation area, mainly comprises the characteristics of a structure, a rock mass, an alteration zonal and the like, and identifies and determines an ore finding target area, namely an ore deposit point.
The target step is a point medium body finding, namely, various mining area data (mainly with large scale) are further analyzed in detail, including various latest detection data (three-dimensional) in the deep part, geochemical indicating elements, a directional prediction theory and a directional prediction method, and the like, so that a mining (chemical) body is found.
And the third step of finding three key points of the oversize mine, wherein the first point is a specific mining mode, the second point is expert judgment (preference), and the third point is comprehensive verification and the like. The three can complement and promote each other. So far, different scholars propose hundreds of mineralization patterns of different ore species, but a specific mineralization pattern refers to a few mineralization patterns which have been or are considered to form oversized deposits. Thus, finding oversized deposits is primarily a matter of seeing that the major features of the deposit do not fit into these few deposit patterns, although perhaps new types of deposit discovery do not preclude the possibility of finding oversized deposits. Such as gold deposits greenbelt, altered rock and karlin gold deposits can often form oversized gold deposits. If experts think that the geological characteristics and the altered mineralization characteristics of gold ores in a certain area are very similar to one of the three mineralization modes, large gold deposits are very easy to find in the area. For example, in the discovery process of Zhuxi super-large tungsten ore, according to related personnel, firstly, the layered copper ore in the center area of the Qinzhang finished ore zone and secondly, the slightly shallow layered copper ore is discovered by applying a multi-bit-integrated mode vacancy prediction and finding that 50 meters of white tungsten mineralized small-layer front edges except for copper mineralized in ZK4205 holes in the drilling data of the former people, and the discovery of finding towards the deep part by the technical personnel is most important.
The oversize deposit in the invention is a deposit with a large reserve size more than 3 times larger than the metal amount of the ore. In view of the many similarities in the habits of gold and uranium and the many large ultralarge auricles that tend to accompany them, such as the uranium-bronze rare earth deposit in the olympic dam of australia and the uranic deposit in the rubble rock type of vittwolland in south africa, gold and uranium are always mineralised together. In the latest research, tungsten and copper mineralization conditions are similar to the background and are also mineralized together, the quantity of associated copper metal in the first and second large tungsten ores in the Gangxi north world can reach large scale, and tungsten and copper are main nonferrous metal ores, so that the nonferrous rare metal ores of gold, uranium, tungsten and copper are discussed together. The method is practical and feasible, has great significance for shortening the period of finding the mine, reducing the risk, saving the cost and improving the success rate of finding the mine, and has strong guidance on the actual work of finding the mine, particularly the strategy of finding the mine and purchasing the right (going out) of the participating stocks in a new area or country.
