Abstract
The authors consider the problem of reducing the dredge performance when operating at subzero air temperatures. This problem is particularly relevant for deposits located in the Far North, where the dredging season is limited by climatic conditions. During the period of subzero air temperatures dredge performance decreases significantly due to the icing of dredge structure. In consequence, dredging operations are terminated until the occurrence of favorable conditions for work. In this regard, the authors propose a method for isolating the open-pit mine with a hangar made of contemporary construction materials. Cellular polycarbonate, which has several advantages, was chosen as the most promising material for insulating dredging works. The article offers the technical and technological solutions for the proposed method of extending the dredging season. The costs of a dredge hangar for dredges of different sizes and the annual cost of its movement are calculated. A method has been developed for determining the optimal maneuvering angle of the dredge and the width of the single face, whose values depend on the type of dredge and the gold content in the sand. The areas of dredge hangars are determined by the graphical-analytic method. The article presents an example of the air temperature dynamics in a dredge hangar during the year, as well as determines the duration of the mining season.
期刊介绍:
Scientific Mining Journal, which is published i n open access electronic environment and i n printed, is a periodical scientific journal of Union of Chambers of Turkish Engineers and Architects Chamber of Mining Engineers. The name of the journal was "Mining" until June 2016 and it has been changed to "Scientific Mining Journal" since September 2016 because it can be confused with popular journals with similar names and the ISSN number has been updated from 0024-9416 to 2564-7024. Scientific Mining Journal, published four times a year (March-June-September-December), aims to disseminate original scientific studies which are conducted according to the scientific norms and publication ethics at national and international scale, to scientists, mining engineers, the public; and thus to share scientific knowledge with society. The journal is in both Turkish and English. The journal covers theoretical, experimental, and applied research articles, which reflects the findings and results of an original research i n the field of mining engineering; review articles, which assess, evaluates, and interprets the findings of a comprehensive review of sufficient number of scientific articles and summarize them at present information and technology level; technical notes, which may be defined as a short article that describes a novel methodology o r technique; a case studies, which are based on the theoretical o r real professional practice and involves systematic data collection and analysis.
