The amount of land disturbed by facilitating these resources which are of vital interest for the development of every modern society can be used as a key indicator for a number of sustainable development issues associated with a mining activity. In this work, a new methodical approach for estimating land requirement for surface copper mining operations is introduced. For the reference year 1998; facts and figures concerning global land requirement for surface copper mining operations are presented. The work closes with a short discussion and gives an outlook to forthcoming research.","PeriodicalId":195550,"journal":{"name":"Mineral Resources Engineering","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126616824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, the mathematical equation that best describes the shape of the extraction drawbody is given by the Bergmark-Roos Equation. The derivation of the Bergmark-Roos Equation is reviewed and a revised version of the equation is developed which accounts for a non-zero opening width. Equations for the area, volume, and maximum width of the drawbody for a given extraction height are developed for both the original and modified forms of the Bergmark-Roos Equation. The equations derived can be used to evaluate existing mine layouts as well as in the design of new mining geometries.","PeriodicalId":195550,"journal":{"name":"Mineral Resources Engineering","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116971811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kahriman","doi":"10.1142/S0950609802000987","DOIUrl":"https://doi.org/10.1142/S0950609802000987","url":null,"abstract":"Although many research studies were carried out in the past to eliminate environmental issues produced from blasting, unfortunately a general approach or formula has not been established yet due to the complexity of the matter. In addition to the wave and ground motion characteristics, the complexity of blasting parameters and site factors restrict the development of a general criterion. Therefore, experimental site-specific studies should still be done for predicting and controlling the blasting effects. This paper presents the results of ground vibration measurements induced by blasting, which were performed during the tunneling for Istanbul Subway. Within the scope of the study, ground vibration components were measured for all blast events using 4 different types of vibration monitors during the advancement of about 300 m length of the tunnels which required blasting over a long period, for the estimation of the peak particle velocity, and to determine the slope of the attenuation curve together with the maximum charge per delay for the test site. At the end of the statistical analysis of the data pairs, a final relation is developed between particle velocity and scaled distance.","PeriodicalId":195550,"journal":{"name":"Mineral Resources Engineering","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133440973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A NEW DIMENSION TO STUDIES OF SPONTANEOUS COMBUSTION OF COAL","authors":"R. N. Singh, J. Shonhardt, N. Terezopoulos","doi":"10.1142/S0950609802000938","DOIUrl":"https://doi.org/10.1142/S0950609802000938","url":null,"abstract":"Spontaneous combustion of coal is a hazard frequently encountered in coal mining. It has been researched extensively but the actual mechanism by which it occurs is not completely understood. Under suitable conditions, the spontaneous combustion hazard manifests itself in all major aspects of coal mining, namely, underground coal mining, surface mining, stockpiling of coal at the pithead, power stations and ports, during sea-borne transport and stacking of reject material. In underground coal mining, the most difficult situation occurs when spontaneous combustion takes place in the presence of an inherently explosive atmosphere which may promote a local spontaneous combustion incident into an explosion hazard involving the entire mine. Such an incident at the Moura mine in Central Queensland resulted in greater pressure on mine operators for the safe management of spontaneous combustion in their underground coal mines than ever before. As not all coal mines are equally liable to spontaneous combustion due to the different propensities of different coals to self-oxidation, the risk assessment for spontaneous combustion is a primary requirement for the development of a spontaneous combustion management plan for a mine. Once the coal seam has been classified into various categories of spontaneous combustion risk, it is necessary to determine a fire ladder for the coal seam. This should be followed by detailed planning of the mine layout including the mine ventilation system and a spontaneous combustion monitoring program before devising a spontaneous combustion management plan as required by the Coal Mines Underground Regulations 1999. In this paper, a case history is presented which includes the development of a spontaneous combustion management plan for a high-risk coal seam in a greenfield site, from the risk assessment stage to the outbreak stage of a spontaneous combustion incident. It is concluded that the risk assessment, evaluation of the fire ladder, comprehensive monitoring by a tube bundle system and trending of carbon monoxide/oxygen deficiency ratio (Graham's ratio) and CO levels were the main elements in an effective spontaneous combustion control system for the mine.","PeriodicalId":195550,"journal":{"name":"Mineral Resources Engineering","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130212167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
