Description

Roblox association of fans of Coal mines and related topics. The National Coal Board (NCB) was created when the british coal industry was nationalised in 1947 and ran British coal mines until 1984. This group is for discussion of all topics relating to coal mining and to share games related to mining. Deputy- Was in charge of a shift, consisting of about 30 miners with various jobs. Superintendent- At least 1 superintendent was in the mine at any time, Deputy's report any incidents to superintendents. They are responsible for what happens in the mine. How get promoted: Promotion to deputy; Show outstanding of knowledge of mining. Promotion to Superintendent: Meeting with president/ manager and show devotion to group. 'purplediarmid' is currently running the group for me, you can still message me or him for any questions. Feel free to ask questions on the group wall, I or another group member will try our best to answer it! :)

Growth

2 measurements spanning 8 days, net +1. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 184–185 and does not start at zero.
