Massive pillars, which have been left in place for stability, limit mining activity. Backfilling allows for safe recovery of the ore remaining in pillars and assures long-term stability. The high rock stresses which result from deep mining operations can be relieved by backfilling. Initially, waste rock was used to fill the openings left by mining operations, though with mixed results. The need to improve safety and reduce costs has prompted the mining industry to investigate alternative backfill methods. Hydraulic filling with Portland cement has shown considerable promise, but little has been done to define the parameters for an effective design. The objective of this paper is to enhance the understanding of current paste backfill practice. Sixty to seventy weight-percent solids-cemented backfill slurries are currently being used in the mining industry (as a matter of practicality). However, deficiencies in this particular ratio need to be examined. Physical properties of mine tailings are unique based on their geology and the milling process. Flaws in the cemented backfill slurries are usually a result of poor hydration and slime build-up to levels that cause additional dewatering, high equipment/operating costs, and work delays. Furthermore, the required strength and quality of the fill may be affected by high water-cement ratios, as well as by its consolidation time, permeability, and volume changes.","PeriodicalId":195550,"journal":{"name":"Mineral Resources Engineering","volume":"10 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":"129134873","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}

Only 10 responded, with 3 from Australia and 7 from the USA One of the responses was from an underground mine, and relevant portions were included in the results. In summary, it was found that inverse distance and geostatistical methods were used the most in calculating resources and reserves in the exploration stage. This was usually done by a team consisting of a geologist, a mining engineer and a metallurgist/geotechnical engineer. In some cases, an outside consultant reviewed the calculated resources/reserves. During production, the polygonal method was most widely used, followed by geostatistical methods. Most mines indicated that duplicate samples were assayed and that statistical analysis was done to check the validity of the sampling and assaying practices during both the exploration and the production stage. The majority of the mines surveyed indicated that a gold content versus particle size distribution study was carried out on the blast hole cuttings.","PeriodicalId":195550,"journal":{"name":"Mineral Resources Engineering","volume":"200 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":"114656719","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}

So far, various types of formulations or solution methods have been proposed with mining systems, but most of them exclusively considered linear functions as objective functions. Real world study is decision making under subjective constraints of different importance, after using uncertain data (linguistic variables), where compromises between competing criteria are allowed. It seems however that this technique is still very little known in mining. It is one of the aims of this case study to disseminate this technology in many mining fields. The paper is divided into four sections. The first section provides an overview of the underlying concepts and theories of multiple attribute decision making in a fuzzy environment and the scope of this type of search. The second section introduces few applications of fuzzy set theory to mining industry problems reported in the literature. Some of these applications are briefly reviewed. The third section presents two case studies which illustrate the application of the system for equipment selection in surface mining and method selection in underground mining in a fuzzy environment, and highlight the flexible nature of the approach. Details of alternative systems and their criterion of each operation are given. And finally the fourth section presents the concluding remarks.","PeriodicalId":195550,"journal":{"name":"Mineral Resources Engineering","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134010985","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}

This paper presents a new approach to quantify the impact of such problems in underground hardrock mining and considers the links between mine planning and ground-related problems. A classification of the various types of potential problems is presented, based on a review of case studies and the surveillance of ground failures in several mines in Ontario, Canada. Despite serious efforts to advance the effectiveness of design in such underground mines, ground-related problems still cannot be totally avoided. A time-dependent internal risk model was established to quantify the impact of ground-related problems in mine production systems. Subjective probabilities provide the input for a reliability analysis, which derives the required input parameters for production simulation. Reliability analyses that are currently used to calculate the reliability of mine equipment were applied for the case of mine subsystems with ground-related problems. A cost impact model is presented that is dependent on the parameters determined in a reliability analysis.","PeriodicalId":195550,"journal":{"name":"Mineral Resources Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128702593","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}
