Kiruga asked:
What element is buried in the ground in especially mining areas and telecommunication masts?
I am told the same substance used for conducting lightening into the ground in preventing strikes against lives and property, is what is applied.
Could i know also why and what the colonialists several decades ago were burying especially on hill-tops in say; East African countries and highly protected?

There are no special elements that would be buried for these purposes. Any good conductor will do. Copper was probably used in many cases, but lightning conductors can as well be made of steel. Zinc plated materials come to mind (for rust protection) and Zinc might also have been used for sacrificial electrodes (to keep the main electrode from corroding). The Zinc forms a kind of battery with the dirt and moisture in the ground. The current from that “battery” protects the actual metal that would provide the grounding in case of a lightning hit. I do not know if this was or is common practice in Africa.
It might be that the technology has changed between colonial times and modern times. But that would be based on better knowledge of how to make lightning protection systems and likely occurred worldwide. It would not be a particular feature of colonialism in Africa.
