Panasyuck A. Estimation of spatial placing and productivity of pegmatites with the purpose of them geometrical analysis for the ground of parameters of their development by an underground method

Object: structure and geometrical parameters of pegmatite's beds of the Volynsk quartz's province, purpose: establishment of conformities to the law of structure and spatial placing of pegmatites, them geometrical analysis on this basis for the ground of parameters of underground development of pegmatite's beds, methods of researches: analysis of literary sources and existent experience of secret service and development of beds of quartz raw material; technical and economy analysis; methods of the applied and mathematical statistics with the use of the computing engineering; analytical and graphic analysis methods; mathematical design; methods of the optimum planning of numeral experiments, and also mining and geometrical analysis and high-quality indexes of pegmatites. It is first set that construction of model of pegmatite in isolines is provided by determination of quantitative indexes of high-quality descriptions on the basis of computers and GIS-technology, mathematical description of conformitiesto the law of structure and spatial location of pegmatite's beds, which serves as pre-condition of ground of parameters of underground development of pegmatite's beds. It is set that pegmatites are characterized by the zonal structure; they have the isometric apeak compressed forms which geometrically can be described by the ellipsoid of rotation about longitudinal axis. Volumes of pegmatites, the sizes of quartz kernels and myarol of mineral genesis depend on the geographical location and change from a north to the south and westerly east, described by parabolic dependences. It is first set that productivity of pegmatite's bodies depends on their structure, power of body and color of feldspars. The results of researches are realized in the technological processes of "Kvartssamotsvety" (Zhytomyr region. Volodarsk-Volynsk). The theoretical conclusions of researches are realized in an educational process. Sphere of the use: enterprises which are engaged in booty by a crystal raw material underground method; geological subdivisions.
