Development of design features of nanosensors for oil branch is shown. It is established that in modern nanosensors usually influence formation of a working signal as environment qualitative quantitative indices (values of temperature, pressure, speed of migration of fluids, contents of chemical elements, sizes рН, etc.) and the nature (predetermining properties), structure and extent (the geometrical sizes) of nanoparticles of sensitive elements which the studied environment influences, forming as a result this working signal. The basic design of nanosensors and the mechanism of their work is described. Distribution of nanosensors on classes depending on the principles and mechanisms of action …

The article presents the results of thermal analysis of samples of minerals – calcite (limestone), dolomite, magnesite and quartz, as well as their mixtures in the host rock of uranium ore. It has been established that thermal decomposition (dissociation) of calcite occurs in one stage at a temperature of 870°C, magnesite - in one stage at 6500° C, and dolomite - in two stages at 7300°C and at 9100°C. Thermal analysis of a sample of uranium ore showed that, as host rocks, it contains calcite, dolomite, and quartz.

The efficiency of irrigation of stacks is an important component, ensuring the intensification of the heap leaching process in the extraction of metals from poor ores. The study of the irrigation process in heap leaching should be aimed at improving the economic and technological efficiency of the applied irrigation methods. In this regard, the study of the factors affecting the evaporation of leaching solutions in HL will make it possible to make new and improved decisions regarding the devices and methods for the supply of solutions. The influence of coarseness and agglomeration on irrigation efficiency was also considered.

An integrated study on the sandstone hosted uranium deposits on the base of hydrodynamic simulation has been carried out to define optimal field opening schemes. The reservoir simulation and mass-transfer models for selected field opening schemes, ways of optimizing existing facilities and building of optimized scheme are the main results of this investigation.

The Middle and South Tien Shan as orogenic regions with accompanying sharp changes in temperature and pressure (Koshmansai diatreme) are characterized by conditions for the formation of diamond manifestations. Prospects of Uzbekistan for radical manifestations of diamonds are assigned to the activated regions of the Archean (?) With manifestations of Lower Proterozoic eclogite-like formations with a complex of associated alpinotype ultrabasites, as well as alkaline intraplate basaltoids, K1.
