Designing Suitable Variants for Stripping Layla Coal Mine in Samangan

Abstract

Mine stripping is one of the important stages in the planning and preparation of solid mines. Choosing the right stripping method has a direct impact on making the mine as easy to extract as possible and more economically efficient. The Leila coal mine in Samangan Province is one of the largest coal mines in Afghanistan that has not yet been professionally mined.  The purpose of this research is to investigate and select the appropriate variant for stripping this mine based on its geological, topographic, and geographical location characteristics. To prepare the mine for future mining planning and extraction. Regarding the research method, it should be noted that this scientific research was conducted based on field studies and also library studies in the geological section and denudation methods. The necessary information in this article has been collected from relevant authorities of the Ministry of Mines and Petroleum and the Northern Coal Enterprise Directorate. To select the appropriate extraction method, two stripping variants, including inclined piles with horizontal cure slags and piles with horizontal cure slags, were compared in terms of excavation costs and excavation consolidation, and the appropriate method was selected. The research findings show that the total costs of excavation and maintenance (consolidation of excavations) in the first variant are significantly lower than in the second variant. Based on this, it is concluded that the inclined stool with horizontal cure slag is the most suitable method for stripping the Leila mine in Samangan.
