Drift mining Wikipedia
Drift mining is either the mining of an ore deposit by underground methods, or the working of coal seams accessed by adits driven into the surface outcrop of the coal bed [1] A drift mine is an underground mine in which the entry or access is above water level and generally on the slope of a hill, driven horizontally into the ore seam2022年10月1日 The results showed that applying biochar and calcite to post nickel mining soil significantly increased soil pH, available P, organic C, cation exchange capacity, growth of Mucuna sp and Improvement of postnickel mining soil fertility with 2021年12月10日 In evaluating the most suitable mining method, workability, safety and ore dilution and recovery factors of different mining methods were considered and the most suitable method for Bogala mine Critical Evaluation of Industrial Mineral Mining Methods in Sri Lanka2022年11月21日 An extremely important role in the underground method of mining deposits is the type of access, which is the initial stage of the mining operations The main feature of mineral deposits is their exhaustiveness and the inability to restore resources This necessitates the rational management of deposit resources, especially the minimization of resource losses Access to Deposits as a Stage of Mining Works MDPI
