Campaigners against plans for a new opencast mine in Shropshire say they fear the impact on their health and possible damage to historical sites.
Local residents fear noise and dust will spoil the area
UK Coal wants to mine 900,000 tonnes of coal in the Wrekin over five years and is applying for planning permission.
The firm has already had two applications for the beauty spot turned down by Telford and Wrekin Council.
Campaigners say there are concerns for several ancient wells on a smaller hill on the Wrekin, the Ercall.
The Wrekin is a popular Shropshire landmark and visitors can see 15 counties from the peak, according to tourism information.
Pat Johnson, from the Friends of the Ercall group, said they would be stepping up their campaign over the coming weeks.
Those against the plans have raised fears about dust which could be carried in prevailing winds, as well as the environmental impact.
UK Coal have said that opencast mines only last for a few years and they must abide by legal requirements as well as planning obligations.
