The present work substantiates the method of mathematical modeling of metal migration assessment during the exploitation of primary and secondary deposits. The coefficient of environmental load was developed, which represents the dependence of metal migration into the environment on toxicity and time.
The results of the research on justification of the technology of hydraulic transportation of lead-zinc ore of secondary mining in the underground development of Spornoe deposit of Salair ore administration are presented. The developed technological scheme of hydrotransport combines into a single technological chain the transportation and lifting of ore mass with associated water removal and partial preparation of oxidized ores for concentration, significantly reduces the technogenic load on the environment and allows to significantly increase the efficiency of mining and processing as a whole.
The methodology and structure of the database (DB) on methods of elimination of local man-made pollution in rock massifs has been developed. At the stage of DB information model development, the relational data model with the use of the mathematical concept of the theoretical-multiple relation was applied. The choice of a way of the organization of a DB is defined as a result of the analysis of character of the placed information taking into account requirement about maintenance of direct access to it. The database is a set of normalized tables containing modules of information. Compared with databases, the construction of which is based on other principles, normalization provided more efficient operations with the database: adding, modifying and deleting data. Table normalization also allowed reducing the physical volume of the database (the size of its record on the medium) and increasing its performance.
The methodology of database construction on methods of local technogenic pollution elimination in rock massifs is considered. The characteristic of optimal conditions of database application is given, rational type of its data organization is justified. The system of relational relations between the database objects is built on the basis of the information-logical model of the subject area.
