KÖMÜR DİKİŞ MADENCİLİĞİ YOLU İÇİNDE ÇEVRELENEN KAYALARIN ARIZA ÖZELLİKLERİ
In order to provide technical support for grouting engineering of broken surrounding rock in roadway. Taking a certain mine in Jin coal mine area as a test mine, drilling TV and segmented water injection tests were used to detect the damage characteristics of surrounding rocks, and the numerical simulation of stress characteristics during the failure process was carried out. The research results show that the crack width of the surrounding rock can be reduced to four areas from the inside to the outside, and the crack widths are different. After the excavation of the roadway, the stress concentration occurs inside the coal and rock mass. With the excavation, the stress exceeds the strength of the coal and rock mass, and the failure occurs, and the stress concentration phenomenon continues to develop deep; the radial direction of the roadway is divided into four areas: completely broken zone, fracture reduction zone, fractured compression zone and proto-rock-like area.
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.
