Roadheader applications in mining and tunneling industries
Roadheaders offer a unique capability and flexibility for the excavation of soft to medium strength rock formations, therefore, are widely used in underground mining and tunneling operations. A critical issue in successful roadheader application is the ability to develop accurate and reliable estimates of machine production capacity and the associated bit costs. This paper presents and discusse...
متن کاملEstimation of reliability-based maintenance time intervals of Load-Haul-Dumper in an underground coal mine
Reliability estimation plays a significant role in the performance assessment of mining equipment, and aids in designing efficient and effective preventive maintenance strategies. Continuous and random/irregular occurrence of failures in a system could be the main cause for performance drop of machinery. The accomplishment of a projected level of production is possible only by an efficient oper...
متن کاملApplication of Heavy Duty Roadheaders for Underground Development of the Yucca Mountain Exploratory Study Facility
Heavy duty roadheaders of 100 ton weight class are being considered for the excavation of the test rooms and alcoves along the main ramp and in the main repository level at the Yucca Mountain site. The current design of the candidate machines was studied and appropriate modifications are proposed. Computer programs for design optimization and performance prediction of roadheaders were developed...
متن کاملA New Mathematical Model for Production Scheduling in Sub-level Caving Mining Method
Production scheduling in underground mines is still a manual process, and achieving a truly optimal result through manual scheduling is impossible due to the complexity of the scheduling problems. Among the underground mining methods, sub-level caving is a common mining method with a high production rate for hard rock mining. There are limited studies about long-term production scheduling...
متن کاملComprehensive Technical Support for High-Quality Anthracite Production: A Case Study in the Xinqiao Coal Mine, Yongxia Mining Area, China
The effective production of high-quality anthracite has attracted increasing global attention. Based on the coal occurrence in Yongxia Mining Area and mining conditions of a coalface in Xinqiao Coal Mine, we proposed a systematic study on the technical support for the production of high-quality anthracite. Six key steps were explored, including coal falling at the coalface, transport, undergrou...
