The paper presents the results of comparative laboratorial testings physical and chemical properties ion-change resins: BD-706, BO – 020, BO-008, BD-709S, BD- 710M, А-560, А – 508, MS-2040. There are results present, that resins ВО-008, BD-709S, BD-710M and MS 2040 do not comply with requirements ОSТ 95.291-86. Kinet- ics of sorption uranium from sulphuric acid solution and carbonate solution presented, that resin А-560 has the best indexes.
Gis-Based Approach For Sinkhole Occurrence Risk Mitigation In Urban Areas For Historic Wieliczka Salt Mine, Agnieszka Malinowska, Ryszard Hejmanowski

The article presents the results of the definition of a new methodology for assessing the risk of flooding a shallow slotted mine, which was carried out on the square above the Wieliczka Salt Mine, which is a world heritage. Vertical stresses are estimated on the basis of the theoretical state of rock mass deformation in the area of test chambers. In addition, the risk for chambers indicated in the zone was calculated based on the theory of arctic pressure. The final stage of the study was spatial analysis, which led to the identification of chambers, potentially subject to the influence …

he article describes the history of the development of a new type of analysis of geological samples for gamma-activated gold method. The Central Mining Administration of the Navoi Mining and Metallurgical Combine announces the creation of a gamma-activated analytical laboratory at the Muruntau deposit. The prospect of gamma-activated analysis of gold, silver and rare metals in Uzbekistan and around the world.
