The coal geological map filling method has the advantages that the reliability is good, the measuring accuracy is high, the use effect is good, the design is reasonable, the operation is simple and convenient, one set of novel coal geological map filling method with feasibility, three-dimensional viewing and good effect is formed, and the coal geological map filling method is suitable for being popularized and applied.
Description
Technical field
The present invention relates to a kind of geologic mapping method, especially a kind of coal geological exploration map plotting method.
Background technology
Coal field geology charting is the element task of coal geological exploration, its object is exactly by surface geology observation basement rock natural exposure and engineering geology point etc. being carried out to system acquisition, edit and record, synthetic study succession of strata, rock, structure, seam contrast and surficial geology rule, the relevant geological map of establishment reflection coal field geology feature, Oceurence Patterns of Petrographic Facies, for coal geological exploration respective stage provides foundation ground geologic information.
Existing coal geological exploration charting order: collecting zone topomap → indoor Data acquisition, → field reconnaissance → measured section, trenching construction edit and record → charting → Report workout.
Selected the topomap of corresponding proportion chi according to the different exploration stage in the past, hand-held topomap contrasts with natural actual landforms in the wild, particle definitely on figure, originally geological phenomenon is being described by special paper record, manual drawing sketch map, operating accuracy and field work amount are all very large, when running into severe weather conditions, also cannot carry out the work.Have the geological work cycle long, artificial amount is large, inefficiency, and charting achievement is not directly perceived, mainly utilizes planimetric map and sectional view to carry out combinational expression, masks the in-layer heterogeneity of reservoir, have some limitations.
At present, along with the development of informationization technology, adopt computer technology can carry out 3 D visible geologic mapping completely, one is that topomap, minute book etc. are not carried in field, two is that field geology point sketch both can directly have been taken a picture generation, also can cut one piece of object profile at artificial filling geology lines from satellite photo through the stereographic map of 3D processing.Three is utilize ALOS satellite image map clearly interpretation can go out the geological phenomenons such as landslide, avalanche, after striograph determines position, can observe fast.Thus overcome the defect of the method for traditional coal geologic mapping.
Summary of the invention
The invention provides the coal geological exploration map plotting method that a kind of result of use is good, measuring accuracy is high.
Realize a kind of coal geological exploration map plotting method of the object of the invention, comprise the steps:
(1) collecting zone image picture: according to Coal Exploration demands, selects certain proportion chi precision to collect aviation, the satellite image picture information of digitizing and three-dimensional, directly loads portable computer;
(2) indoor Data acquisition: collect topomap according to the certain proportion chi precision of designing requirement, through digitized processing, or directly collecting Digital Topographic Map ' and digitized solid, to defend sheet stacked, field according to map size and charting requirement, very convenient identification terrain and its features;
(3) the direct charting in field: directly fix a point on computers, describes rock, describes structure phenomenon; Adopt recourse method, pass through method, stratum should be divided in detail, set up correct succession of strata, determine mapping unit;
(4) material computation machine input: appear in rock stratum, outcrop of coal seam, structure, old kiln earth's surface exposure place, fix a point with high-precision GPS, Unified number, the source book of rock characteristic, structural attitude, the distribution of old kiln, direct editing is in computing machine, and it is hiding to build storehouse, directly clicks display when needing;
(5) geological map generates: according to the planimetric coordinates (X of geologic mapping earth's surface observation station, Y), the geological information point data of elevation (Z), to the feature such as coal-bearing strata, coal seam growth, structure in geologic mapping district carry out visual, demonstrate intuitively; The primary scale terrain and geologic map corresponding to national standard specification, regional geological map, measured section map can be generated by interpolation of data;
(6) Report workout.
The beneficial effect of a kind of coal geological exploration map plotting method of the present invention is as follows:
A kind of coal geological exploration map plotting method of the present invention, good reliability, measuring accuracy is high, and result of use is good, reasonable in design, easy and simple to handle, has defined a set of feasible, three-dimensional visible, effective novel a kind of coal geological exploration map plotting method, has been convenient to promote the use of.
