This document summarizes chromite mining practices on the Great Dyke in Zimbabwe. It describes the current resue stoping method used to mine chromite seams, which involves drilling and blasting waste rock and carefully lifting the chromite ore. It also discusses previous attempts at mechanization that failed. Future mining methods being considered include narrow reef stoping where all material is hoisted out without waste packing, requiring new shaft and layout designs to accommodate increased waste rock hoisting.

Los cientÃficos colocaron cinco monos en una jaula con una escalera y plátanos. Cuando un mono subÃa, los otros eran rociados con agua frÃa. Luego, los monos golpeaban a cualquier mono que intentara subir, aunque ninguno habÃa recibido agua. Cuando los monos fueron reemplazados, continuaron golpeando a los nuevos, a pesar de no conocer la razón original.
Nuclear fusion is the process by which lighter atomic nuclei fuse together to form heavier nuclei, releasing enormous amounts of energy. It is the process that powers stars like our Sun by fusing hydrogen into helium. Researchers are working to develop fusion as an energy source on Earth by containing and heating hydrogen isotopes to fuse in reactors such as tokamaks using magnetic and inertial confinement. Fusion reactors could provide safe, sustainable, and virtually limitless clean energy but developing viable commercial fusion power remains an engineering challenge that requires overcoming high costs and achieving breakeven where energy output exceeds energy input.
