About scientific and practical conference explosives of the Urals

The article reviews the results of the VIII Scientific and Practical Conference with international participation "Technology and Safety of Drilling and Blasting Operations in Surface and Underground Mines of the Urals" which was held at the Ekaterinburg-EXPO Exhibition Center and the Uralasbest Industrial Complex as part of the IX Urals Mining Industry Forum and the URAL MINING' 21 Exhibition dedicated to the Year of Science and Technology in the Russian Federation and the 30th Anniversary of the Urals Mining and Industrial Association. The article also informs about the winners of the Ural Mining Award 2021 and about the research and engineering reports and presentations made during the conference and dedicated to blasting operations. Results are summarized of the visiting seminar at the Uralasbest Industrial Complex, where the Chief Engineer of Promtekhvzvzryv Company N.A. Chistyakov and General Director of the Urals Explosives Association G.P. Bersenev conducted tours to the open-pit mine, the 'Poremit' Plant - the first emulsion explosives production facility in the Urals, a bulk explosives storage, the museum and training center of the Urals Asbestos Mining and Processing Complex. Following the tours of the training center site of the Processing Complex, the second part of the conference was held, during which a number of reports were delivered. Upon completion of the seminar, the Urals Explosives Association awarded honorary certificates and valuable gifts to specialists of the Promtekhvzvzryv Company for their contribution to improvement of drilling and blasting technology and organization of labor on blasting sites. The article is concluded by a summary of the Conference's decisions.

Archaeological Evidence of Migration from the Southern Taiga of Western Siberia to the Urals in the Early Middle Ages: The Vodennikovo-1 Cemetery

We describe 15 burials at the Vodennikovo-1 group of mounds in the northern Kurgan Region, on the Middle Iset River, relevant to migration processes during the Early Middle Ages. On the basis of numerous parallels from contemporaneous sites in the Urals and Western Siberia, the cemetery is dated to the late 7th and 8th centuries. Most of single and collective burials are inhumations in rectangular pits with a northwestern orientation, with vessels, decorated by carved or pricked designs, placed near the heads. These features, typical of the Early Medieval Bakalskaya culture of the Tobol and Ishim basins, are also observed at the Pereyma and Ust-Suerskoye-1 cemeteries in the same area. However, there are innovations such as inlet burials, those in blocks of solid wood and plank coffi ns, western orientation of the deceased, and placing vessels next to the burial pits. These features attest to a different tradition, evidenced by cemeteries of the Potchevash culture in the Tobol and Ishim basins (Okunevo III, Likhacheva, and Vikulovskoye). Also, Potchevash and Bakalskaya vessels co-occur at Vodennikovo-1, and some of them (jugs with comb and grooved designs) are typologically syncretic. To date, this is the westernmost cemetery of the Potchevash culture, suggestive of a migration of part of the southern taiga population from the Ishim and Tobol area to the Urals.

THE USE OF CHILD'S AND WOMEN'S LABOR AS A SOURCE OF REPLENISHMENT OF LABOR IN THE MINING PLANTS OF THE URALS AT AN EARLY STAGE OF THE GENESIS OF CAPITALISM

The article deals with the issue of the use of children and women there, their number in metallurgical plants, mines and gold mines of the Urals at an early stage of the emergence of capitalism. The methods of both economic and non-economic coercion of young children and women are investigated. The study examines working conditions, working hours, wages, food, housing conditions, and the state of medical care.

Productivity and quality of fiber’s varieties and selection numbers of flax in the Urals of the nonblack earth zone of Russia

In the Ural of the nonblack earth zone of Russia, fiber flax variety Diane from France and selection number ER-138 from Russia stood out in fiber yield. One of the parameters for obtaining a homogeneous fiber of fiber flax is the technical length of the stem - not less than 60 cm, the thickness of the stem - not less than 500 units. The selection number K4196 × 1288/12 and the variety TOST 4 from Russia, which were characterized by a high technical length (61.2 - 61.8 cm) and dryness (472 - 509 units) of the stem in all the years of study in relation to the standard grade. The indicated breeding numbers and varieties, distinguished by yield, technical length and stem thickness, can serve as a starting material in the breeding process.

Radioepidemiological studies in the Urals: outcomes and future directions

The paper presents the key milestones and outcomes of 65-year studies of the carcinogenic consequences of accidental radiation exposure of the population of the Urals region. The radioactive contamination of the Techa River and the 1957accident at the Mayak PA were the reasons for the long-term exposure of the population at a wide range of doses. The most important tasks of the study were the reconstruction of individual doses, follow-up of the health and life status of cohort members. The research results have shown that chronic human exposure, in comparison to acute exposure, does not reduce the risk of developing malignant tumors and leukemias, and the value of the dose-rate factor does not exceed “one”. Thus, according to our data, the current recommendations of the International Commission on Radiological Protection underestimate the radiation risk of malignant tumors and leukemias in case of chronic exposure of the population by a factor of two. Prospects for further radio-epidemiological studies in the Urals are associated with the analysis of the cohort of Southern Urals Populations Exposed to Radiation (SUPER), which includes about 63 thousand exposed people and makes it possible to assess the radiation risk of solid cancers of certain localizations, certain types of leukemia, and non-cancer effects.
