Description
Technical Field
The invention relates to the technical field of deep exploration of mineral resource exploration, in particular to a three-dimensional positioning method for an ore-forming position of a deep mineral deposit.
Background
China is a large mineral resource consumption country, and with the rapid increase of the mineral resource demand in the development of the economic society, the mineral resource supply and demand in China are short, and the national resource safety is seriously threatened. Meanwhile, as ore deposits such as outcrop ores and shallow ores which are easy to find are fewer and fewer, finding a deep large-ultra large ore deposit becomes a necessary choice for relieving the resource crisis. However, the deep ore deposit has complicated geological conditions and very high ore finding difficulty, and how to determine the position of the deep ore deposit is a neck technology for restricting deep ore finding.
In the aspect of metal ore exploration, the traditional ore exploration method mainly adopts a magnetic method, an electric method or an electromagnetic method instrument and a geochemical method to detect possible occurrence positions of ore bodies. However, because the deep ore body (with the depth of 500-3000 m) has a large buried depth and the overlying thick large body has a serious shielding effect, the traditional ore exploration method has difficulty in identifying the information of the deep ore deposit. The invention solves the technical problem of neck clamping for positioning fractured seepage flow alternating type mineralized deep ore body through a large number of experimental researches and exploration practices. The method has important significance for promoting deep mining and improving resource guarantee capability in China.
Disclosure of Invention
The invention aims to position occurrence positions of deep ore bodies and provides a three-dimensional positioning method for the occurrence positions of fractured seepage flow alternating type mineralized deep ore deposits. The method is based on the ore control fracture and ore body coupling of fracture seepage flow cross-substitution mineralization deep ore deposit, aims at the fracture structure occurrence gradient of the complex massive geologic body, provides fracture three-dimensional model data indexes for judging deep ore forming positions through a large number of experimental researches and exploration practices, and realizes deep ore finding technical innovation based on the ore forming rule.
The technical scheme of the invention is as follows: a three-dimensional positioning method for mineral-forming positions of fractured seepage flow substitution type mineralized deep mineral deposits is characterized in that a three-dimensional geological model for controlling ore fracture is established, and favorable mineral-forming positions are defined according to the three-dimensional spatial characteristics of fracture, and the method specifically comprises the following steps:
(1) in a fractured three-dimensional space model, a fracture section with a steep and gradual gradient angle from a shallow part to a deep part is an optimal section for the occurrence of a deep ore deposit, and the ore deposit is in a gentle section with a surface gradient ranging from 10 degrees to 40 degrees;
(2) the surface change rate of the fracture is large, which is beneficial to mineralization concentration, and the surface change rate of the fracture three-dimensional analysis is more than 3.82, which is the most beneficial position for occurrence of ore bodies;
(3) in the fractured three-dimensional space model, the gradient change of the mineralization enrichment region is smaller than that of the peripheral buffer region, and the difference value of the mineralization enrichment region and the peripheral buffer region is more than 5 degrees.
Further, the method comprises the following specific steps:
s1: gathering existing geographic, geological mapping, geophysical exploration, drilling and mining data of a mining area;
s2: processing the data such as geological semantic consistency, format standardization, space consistency and the like, and arranging the data into a data format required by modeling software;
s3: selecting geological map filling data, drilling data, an exploration line profile and the like according to the exploration working degree or a modeling data source, and constructing a three-dimensional geological model by using proper geological modeling software;
s4: extracting ore control fracture data in the three-dimensional geological model, performing fracture three-dimensional space analysis, forming relevant three-dimensional views of fracture three-dimensional morphology, fracture gradient change, fracture surface change rate and the like, and acquiring main numerical indexes;
s5: according to the key characteristics of the positioning ore body (the fracture inclination angle range is 10-40 degrees, the fracture surface change rate is more than 3.82 degrees, and the gradient change difference value is more than 5 degrees), the occurrence position and range of the deep ore body are defined on a three-dimensional space.
The main principle of the invention for positioning the ore-bearing position of the deep ore body is as follows:
the heterogeneity of geological structure. When the earth crust is affected by stress, the rock stratum is broken by mistake or is cracked, namely the fracture is formed. Because the rocks constituting the crust rock stratum are not uniform, a certain area is often composed of a plurality of rock types, the rocks have large differences in physical and mechanical properties, and when a fracture occurs, the fracture resistance of different rock types is different, so that the fracture characteristics, the size of the inclination angle of the fracture surface and the like are different, for example, when the fracture cuts through a relatively brittle rock stratum, the rock stratum is easy to break, the fracture directly cuts through the rock stratum, and the inclination angle of the fracture surface is relatively steep; when the fracture cuts through the rock stratum with relative toughness, the rock stratum is not easy to break, the fracture can extend along the trend of the rock stratum and gradually cuts through the rock stratum in the direction with a smaller included angle with the rock stratum surface, and the inclination angle of the fracture surface is relatively slow. It is precisely because of the heterogeneity of geological structures that fractures do not cut through rock formations generally in a straight line, but often undergo repeated steep and gradual stepwise changes in dip angle from shallow to deep.
Natural property of fluid mineralization. The formation of deposits is the result of the redistribution and redistribution of elements, i.e. the process of element migration. The mineralizing fluid is a liquid or gas which dissolves, transports and precipitates mineralizing substances, and is generally based on water or water vapor and contains super-soluble gases, such as CO2、CH、H2S, HF et al and H+、HS-、Cl-、K+、Na+、Ca2+Simple ions, chloride complex ions and the like, and various mineral elements are dissolved in the solution. The mineralizing fluid is typically present or trapped in fissures, crystal voids, pores, layers, etc. in the subterranean rock. When the rock stratum is fractured, local physical and chemical conditions are changed, the stress balance of the underground space is broken, fluid is gathered to the fracture, and the fluid is transferred from a high-stress area at the deep part of the fracture to a low-stress area at the shallow part of the fracture. When meeting the position with large change rate of the fracture surface, the temperature and pressure conditions of the fluid are changed rapidly, and the fluid can unload part of mineralized substances, so that the mineralized elements are enriched into the mineralized ore at the position with large change rate of the fracture surface; when the ore-bearing fluid moves along the fracture steep slope section, the ore-bearing hot fluid rises from the relatively high-pressure area of the deep part to the relatively low-pressure area of the shallow part, and flowsThe body is quickly dissipated, and is not suitable for enriching into ore, when the ore-forming fluid is transported to the fracture gentle-inclination section, the fluid transversely and slowly flows under the conditions of relative equal pressure and constant temperature, and the ore-forming substances are preferably enriched into ore. Therefore, the ore body is mainly in a fracture gentle dip section.
And thirdly, the effectiveness of the three-dimensional modeling technology and functions on deep geologic bodies. The technology for carrying out three-dimensional geological modeling according to geological and geophysical related data is mature, deep geologic body characteristics and three-dimensional geological structures can be effectively displayed by utilizing the established three-dimensional geological model, and big data analysis can be carried out. After the fracture structure is extracted, enough data such as fracture dip angle, surface change rate, gradient change and the like can be obtained, and data analysis, delineation of data change abnormal areas and positioning of favorable three-dimensional space positions of the mining area are carried out.
The invention has the following main beneficial effects: the traditional prospecting method mainly carries out deep mineralization prediction and engineering verification according to two-dimensional geological data of the earth surface; the main mining idea of the invention is as follows: the traditional ore finding method is combined with the modern informatization technology, the deep geological structure is visually displayed by utilizing the three-dimensional visualization technology, and the deep ore forming position is defined by utilizing the big data analysis technology. The method has the characteristics that the process and the result of the deep ore deposit positioning can be directly observed, the determination of the mineral-forming position is supported by data, and the positioning precision is high, so that the problem of the precise positioning of the fracture seepage flow alternating type mineralization deep mineral-forming position is effectively solved. The invention has remarkable effect in deep prospecting of charred families in Laizhou city of Shandong province and ultra-huge gold deposits in Sanshan island.

Detailed Description
The following describes the embodiments of the present invention in detail with reference to examples.
In the ultra-huge gold mine exploration of the Jiaodong san shan island, a deep mineral deposit endowing position three-dimensional positioning method is adopted to determine the position of a deep mineral deposit, and the specific steps for implementing the method are as follows:
(1) and (6) collecting the data. Gathering data of exploration results of the three-mountain island northern sea area, the three-mountain island gold mine, the west ridge gold mine and the Xinlijin mine, wherein an exploration line section diagram is 81, a drilling column diagram is 311, and 1:1 geological map of 5 ten thousand areas, 5 geological maps of 1:1 ten thousand topography and 1 part of digital elevation data.
(2) And (6) data processing. Firstly, coordinate conversion is carried out on original profile data and ground coordinate data, all the data are uniformly converted into a Xian 80 coordinate system, and a uniform coordinate system is established. And secondly, extracting position information and attribute information used for three-dimensional modeling. Then, the zone file in the profile is converted into a line file, and the part which is irrelevant to ore body modeling is deleted. After the topology error check, the line file is converted into a new zone file, and the new zone file only contains the ore body objects.
(3) Modeling methods and ranges. A three-dimensional modeling method based on multi-source data is adopted, basic geographic data, drilling data and geophysical prospecting interpretation profile data are fused, a three-dimensional spatial data field is constructed by utilizing a spatial interpolation technology, a three-dimensional hardware texture direct drawing technology is adopted for stereoscopic visualization, and spatial distribution characteristics and internal attribute information of a regional stratum structure are expressed in a true three-dimensional form.
The extension distance of the ultra-huge mineral deposit in the direction of the three-mountain island is larger, and a planar geological map scale is adopted to be 1:1 ten thousand, survey line section map scale is 1: 2000, horizontal control mesh size 60m × 60 m. The minimum thickness is set to 0.1 m. Modeling range: 4129876-4147127, Y: 41490458-41503702, the earth surface is-4000 m.
(4) And (5) analyzing the fracture three-dimensional space. The three-mountain island fracture in the three-dimensional geological model is extracted, the general trend of the fracture is 35 degrees, the fracture tends to the south east, and the inclination angle is 35-50 degrees. The fluctuation of the fracture surface is obvious, the inclination angle of the shallow part is steep, the shallow part is gradually reduced towards the deep part, and the body is in a dustpan shape or a ladder shape with the gradient from top to bottom along the inclination direction (figure 1). The relationship between fracture surface slope, surface variation and gold deposit was analyzed as follows:
a. the fracture surface slope. The fracture surface gradient and the ore body grade multiplied by thickness value controlled by the fracture surface gradient are extracted, the average value of the structural surface gradient and the ore body grade multiplied by thickness in different elevation ranges is calculated by taking 20m as a unit, and a distribution broken line graph (figure 2) of the fracture surface gradient from shallow to deep and the ore body grade multiplied by thickness value is manufactured. It can be seen that the fracture surface slope varies greatly, generally slowly-steeply-slowly from shallow to deep, with a large number of local variations; the ore body grade x thickness value is also changed greatly and is in a trend opposite to the fracture surface gradient on the whole, namely the ore body grade x thickness value at the position with the large fracture surface gradient is as small as 0, and the ore body grade x thickness value at the position with the small fracture surface gradient is obviously increased. This indicates that the fracture gentle dip section is likely to be mineralized.
b. Rate of change of fracture surface. And calculating the surface change rate of the three-mountain island fracture, and grading the calculation result by adopting a natural discontinuity grading method. The variance of each kind of data is calculated firstly, then the sum of the variances is calculated, and the variance sum is compared and used as a classification basis. The three-mountain island fracture zone is divided into 8 grades according to a natural discontinuity classification method, wherein the grades are respectively 0.00-1.91, 1.91-3.82, 3.82-5.73, 5.73-7.64, 7.64-9.55, 9.55-11.46, 11.46-13.37 and 13.37-15.29. In summary, the fracture surface is relatively flat, the surface change rate is generally less than 1.91, and the contour line of the grade x the thickness of the deposit and the value of the change rate of the structural surface are superposed (fig. 3), so that the ore body is mainly provided with a region with a large change rate of the structural surface, and the position with the change rate of the structural surface being more than 3.82 is the main distribution range of the ore body.
c. The gradient of the mineralization enrichment area changes. Gradient analysis is carried out on the mineralization enrichment region (the grade is multiplied by 4 times of the thickness value to be used as the mineralization enrichment part) and the peripheral buffer region (the buffer distance is 400m) (as shown in figure 4). The gradient of the buffer zone is 19.24-87.33 degrees, the average is 52.06 degrees, the gradient is mainly concentrated between 30-70 degrees, and the gradient change coefficient is 26.23 percent; the inner gradient of the mineralization enrichment region is 19.24-51.97 degrees, the average is 43.39 degrees, the concentration is mainly between 35-50 degrees, and the gradient change coefficient is 14.09 percent. On the whole, the slope area in the buffer area range is wide, the slope change is large, and the buffer area is in an abnormal part with large slope change of the structural surface; the concentration of the gradient distribution in the mineralization enrichment region is low, the mineralization enrichment region is positioned at a relatively flat part of a structural surface, and the difference value of the two is 8.67 degrees.
(5) And (4) performing position analysis on the deposit. The comprehensive three-dimensional fracture analysis result shows that the occurrence position of the deep part of the Sanshan island ultra-giant gold deposit accords with the following 3 key technical indexes:
a. in a three-dimensional fracture model, a fracture section with a steep inclination angle and a gradually-changed angle from a shallow part to a deep part is an optimal section for the occurrence of a deep deposit, and the deposit is caused to have a surface gradient within a range of 10-40 degrees.
b. The surface change rate of the fracture is large, which is beneficial to mineralization concentration, and the surface change rate of the fracture three-dimensional analysis is more than 3.82, which is the most beneficial position for the occurrence of the ore body.
c. In the three-dimensional space model, the gradient change of the mineralization enrichment region is smaller than that of the peripheral buffer region, and the difference value of the mineralization enrichment region and the peripheral buffer region is more than 5 degrees.
By adopting the method and the implementation steps, the three-dimensional space characteristics of the ultra-huge gold deposit in san shan island, Lai, Jiaodong are analyzed and guided. The method of the present invention was confirmed to be effective.
