How continuous surface mining and drill and blast can work together on the same mining site

Global Mining Review,
Whether you are mining limestone, bauxite, or one of the many other minerals found around the world, you want the rocks to be broken down to a manageable size. On a mining site, your options are limited by the infrastructure and environment surrounding your work area.
You have two main options: You can drill and blast with explosives and size the rock with a primary crusher, or you can use a continuous surface mining (CSM) method. In most cases, the material being produced by a CSM is a consistent, 5 in. to 10 in. (12.7 – 25.4 cm) range with few fines and can be fed directly into a secondary crusher if needed. The Vermeer Terrain Leveler® surface excavation machine (SEM), also known as a surface miner, uses a top-down cutting method that delivers rock-penetrating power through its cutting teeth on a rear-mounted drum.
But there are certain mining sites that require the capabilities of both mining methods. Visit protips.vermeer.com for examples of how and when to consider using both CSM and drill and blast on the same mining site.
