Zip World is set to open its first adventure park in south Wales, with the former Tower Colliery forming part of the site.
Three zip wire courses will be created on Rhigos Mountain in Hirwaun.
The company said it wants to bring its “unique brand of experience and adventure” to the Cynon Valley.
Rhondda Cynon Taf council leader Andrew Morgan said plans were passed by the planning committee without a single objection.
He added that the adventure park would open in 2020.
The original attraction, known as Zip World Velocity, opened at Penrhyn Quarry, Bethesda, in 2013.
It is the fastest zip wire in the world, with thrill seekers reaching speeds of 100mph, according to the company.
