1 de ene. de 2021 · This article is focused on underground mining of narrow-width deposits (veins) and the role of economic geologists in the definition and development of these deposits.
Do you see drones playing a bigger role at underground narrow vein mining operations in the future as the complexity of these operations increases? E&MJ asked Gray.
The mining method must be varied for different specific deposits. In summary, there are three dominant techniques worldwide for mining gently-dipping narrow vein: Longwall mining method: this method is suitable for mining bedding deposit with a dip less than 35°, 3-4 m thickness and poor roof.
There are continuing developments in underground narrow vein mining, from innovative mining methods using low-profile equipment to adaptations of current mining methods using equipment such as road-headers.
In this paper, a practical long-term plan and schedule for an underground mine located at Costerfield in Victoria is presented, discussing all main areas of concern regarding narrow vein mining. Enhanced production scheduler (EPS) software is the current tool that is used for long-term planning and production scheduling at this mine.
AMC’s underground capability includes specialization in all aspects of narrow vein underground Mineral Resource and Mineral Reserve estimation, narrow vein mine planning, design, production operations and technical assessments.
Narrow vein stoping is performed in an underground excavation along geological ‘veins’ — distinct sheet-like bodies of crystallized minerals within a rock – where the mineral is mined and removed.
