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.

北方远程砂矿能力的扫描技术
作者考虑了在零度以下空气温度下操作时降低挖泥船性能的问题。这个问题与位于极北地区的沉积物特别相关,那里的疏浚季节受到气候条件的限制。在零度以下的空气温度期间,由于挖泥船结构结冰,挖泥船性能显著下降。因此,疏浚作业将终止,直到出现有利的作业条件。在这方面,作者提出了一种用当代建筑材料制成的机库隔离露天矿的方法。多孔聚碳酸酯具有多种优点,被选为最有前途的绝缘疏浚材料。本文对延长疏浚季节的建议方法提出了技术和技术解决方案。计算了不同尺寸挖泥船的疏浚机库成本及其每年移动成本。开发了一种确定挖泥船最佳操纵角和单面宽度的方法,其值取决于挖泥船的类型和沙子中的黄金含量。疏浚机库面积的确定采用图解分析法。本文介绍了一个疏浚机库一年中气温动态的例子,并确定了采矿季节的持续时间。

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.
