POSSIBILITY OF USING GEOMETRIC MODELING TO SOLVE SOME PROBLEMS OF TECTONIC NATURE OF THE POLE CORE BY MEANS OF CAD SYSTEM

Guriev T.S., Tsabolova M.M., Kalinichenko A.V.

Proficient and rational use of wells in various aspects of exploration and delineation of mineral deposits is undoubtedly an urgent task, which includes various mountain-geological scientific and engineering problems and which can be solved through geometric modeling and wider use of CAD system. Geometric modeling of wells allows to solve problems of exploration and delineation of mineral deposits and designate them as the system of design automation.
Examined one of the directions of subsoil geometry, associated with extensive use of computers for solving different geological, scientific and engineering problems.
The pole core is used to obtain various information about the geological structure of a site of tabular deposits. With its help it is possible to obtain physical-mechanical, structural properties of the deposits and estimate its reserves. For this purpose certain amount of exploration wells in the survey area of the mineral deposit are used.
Geometric modeling of wells is based on the techniques of their approximation with classic geometric images. From a geometrical point of view a well is a cylindrical surface. Consequently, geometric shape of a core is a circular cylinder, the section of which with a plane can represent in a variety of situations circle, ellipse or two parallel lines. Form of obtained cross section depends on the position of cutting plane relative to the cylindrical surface.
Some positional and metric tasks by the pole core can be solved using the methods of descriptive geometry. Developed geometric algorithm and its mathematical description allows us to make the program automated solution to the problem of determining the occurrence of a layer in the pole core.
