Embodiment Construction

[0027] A method for forming a profile map of a sandstone-type coal mine reserve estimate, comprising the following steps:

[0028] S1: Select an area that requires geological exploration, draw a rectangular exploration line map of the area, and the rectangular exploration line includes several drill holes; and determine the basic exploration line in the exploration line map through the drill holes;

[0029] S2: Determine the scope of the exploration line map, that is, the length and width:

[0030] Taking one end point of the rectangular exploration line diagram determined in the first step as the origin, establish a coordinate system, then the coordinates of drilling hole 1 to drilling hole m in the rectangular exploration line diagram are (X1, Y1, Z1), (X2, Y2 , Z2), (X3, Y3, Z3), ... (Xm, Ym, Zm)

[0031]

[0032] Width of the rectangular exploration line map = [(the highest elevation of the rectangular exploration line map - the lowest elevation of the rectangular expl...

Abstract

A sandstone type coal mine reserve estimation profile map forming method comprises the following steps that S1, an area needing geological exploration is selected, and a rectangular exploration line map of the area is drawn; S2, an exploration line map extent is determined; S3, the position, relative to the lower end of a first geologic body, of a first drill hole in the rectangular exploration line map is determined; S4, an ore body boundary is delineated on the geological profile map; and S5, ore body connection is carried out.

Description

technical field [0001] The invention relates to a method for automatically forming a profile diagram of a sandstone-type coal mine reserve estimation for a digital coal mine exploration system, and in particular to a method for forming a diagram of a sandstone-type coal mine reserve estimation profile diagram. Background technique [0002] In the past, the reserve estimation profiles were mostly completed manually, with heavy workload and cumbersome calculations. With the improvement of the exploration level in the work area, a large amount of drilling data has been accumulated. In order to complete the estimation profile of resource reserves, it is necessary to use the geological data formed by predecessors to form the latest and most complete resource estimation profile, which needs to be rearranged, Mapping greatly increases the workload and reduces work efficiency. With the comprehensive and rapid development of computer technology, the nuclear industry system has devel...
