Top 6 Heavy Machinery Used In The Mining Industryrent1

Jun 06, 2018 When it comes to an industry that relies on heavy machinery on a daily basis, you dont have to look further than the mining industry. Mining projects are taking place around the world to dig up minerals and metals from below the surface of the ground. Heavy equipment may mine these raw materials from the surface, called surface mining, and in underground operations.
