specific Embodiment approach 1

[0009] Specific implementation mode one: the following combination Figure 1 to Figure 6 This embodiment will be specifically described. This embodiment includes the following steps: 1. Taking twice the side length of the square survey network grid determined according to the ore body stability and structural complexity, geostatistics or fractal geometry method as the side length of the basic square, for coalfield exploration Generally speaking, the exploration grid is determined according to the degree of stability of the coal seam and the degree of structural complexity. The state has stipulated the network degree standards for various types of coal fields. The basic line distance of the proven reserves is 250-500m, the common one is 500m, its double is 1000m; 2. One control point is arranged at each of the four vertices of the basic square, and three control points are scattered in the basic square, see diagram figure 1 , D(0,0), E(1000,0), F(1000,1000), G(0,1000), a(200,2...

specific Embodiment approach 2

[0033] Specific implementation mode two; see illustration Figure 8 to indicate Figure 13 , the difference between this embodiment and Embodiment 1 is that in step 2, the three control points distributed in the basic square are a(300,300), b(400,750), c(800, 400); other steps are the same as those in Embodiment 1.

[0034] Compared with Embodiment 1, this embodiment has better dispersibility along the trend and inclination of exploration wells or boreholes in the basic unit in Embodiment 1; in this embodiment, the dispersion of exploratory wells or boreholes along the direction and inclination in supporting units 2. The length between two adjacent control points in the survey network is reduced compared with Embodiment 1, within the range of 0.43 to 0.67 times the side length of the basic square.

specific Embodiment approach 3

[0035] Specific implementation mode three: see Figure 14 to Figure 19 , the present embodiment comprises the following steps: 1. Take twice the side length of the square survey network grid as the side length of the basic square; 2. Arrange one control point at each of the four vertices of the basic square, and distribute three The above-mentioned internal three points are connected to form a triangle, and then a control point is arranged at the midpoint on the right side of the basic square, which is added to the control points on the four vertices of the basic square and the three control points scattered in the basic square. A total of eight control points, connect the control point at the right midpoint of the square with the two control points of the nearby triangle inside, and connect the two square vertices on the same straight line as the control point at the right midpoint of the square with the interior A control point of the nearest triangle is connected respective...

Abstract

The invention discloses a mineral exploration method adopting a rotary and crossed type mineral exploration network, which relates to a mineral exploration method with the aim of solving the problems that the traditional exploration network type exploration method has lower control and investigation degree and the drafting method is unreasonable. The method comprises the following steps of: respectively arranging one point at the four top points of a base square with a definite side length, arranging three points in a scattered manner, connecting the three points into a triangle, and respectively connecting the top points and the inner close control points to form base units; rotating each base unit counterclockwise to form a first unit body, a second unit body and a third unit body; splicing the base unit, the first unit body, the second unit body and the third unit body to form a matched unit, and translating and duplicating to form a crossed net; connecting adjacent two base units with triangle top points which are at the two sides of the common side of two matched units and respectively in two different base units and two different matched units to form an exploration network;arranging exploration wells or bore holes at the control points of the network; making a profile map of two adjacent exploration wells or bore holes in the network; making an ore form map on the basis of the profile map; and making an ore inclination and strike profile map on the basis of the ore form map and completing the exploration work of ores.

Description

technical field [0001] The invention relates to a mineral prospecting method. Background technique [0002] Existing exploration network types (such as square, rectangular, triangular, hexagonal and radial networks) have low fault capture rate, unsatisfactory fold control, The accuracy of ore-breaking intersections is low, the accuracy of ore body boundaries is low, and it is not conducive to geological analysis and research. The improvement of the quality of exploration mainly depends on the grid (exploration well or drilling density). Using the existing exploration network type mineral exploration method, due to the low degree of mutual echo and cooperation between adjacent exploratory wells, boreholes or profiles, it is difficult to carry out geological analysis. The positions can only be directly connected with the trend, and the accuracy is low; the ore body morphology map can only be made according to the parallel inclination and trend profiles, and the echoes and coo...
