I guess the town's committee, who are asking for submissions, want to glorify their mining history. The research I have done reveals that mining was hard work, hazardous, involved children aged 12 and below, and meant a life expectancy of 30 - 40 years!
I did consider featuring a father and son but I'm not sure they want that aspect of mining to be represented.
A miner would have to spend up to 2 hours climbing down wooden ladders just to get to his place of toil. And he would have to climb the trecherous ladders 'up to grass' at the end of an exhausting 8 hour shift. So I thought a miner on a rickety ladder could be quite poignant. But from distance it could look like a fireman.
A 'static' figure would have to be very sympathetically sculpted to convey a look which shows the years of toil, steely determination with a touch of fear etched on his face.
An action figure may have more immediate impact and a look of exertion easier to achieve but I think a statue should evoke an emotion. But then again maybe I'm setting the bar too high.
