Each rock fall stabilization project is different, some may require multiple layers of stabilization.  The following pictures show one such project.  Marco Concrete Lifting stabilized this highwall at a West Virginia coal mine using shotcrete, rock anchors, and rock netting.

This is what this highwall looked like
before stabilization.

Here is another viewing angle of the
highwall before stabilization.

Preparation cleaning using a special
nozzle, shooting high-pressure water.
This is done to remove any loose debris
and other material insuring positive
adhesion of the shotcrete to the rockface.

The first layer of stabilization (Shotcrete)
is being applied over the rockface.

Shotcrete application at project's edge
shows a definitive line between the
shotcreted and non-shotcreted areas.

Rock netting is installed held in place
by rock anchors.  This layer catches any
material that may come off in the future
due to seismic or other reasons.

rock fall stabilization project.
