Safety in Open Pit Mining
Draperies directly act on the stability of the blocks, but also control their fall should failure occur. Such systems are common practice within Australia open pit mines. In surface mining, draperies are used to prevent rock from impacting directly onto the concrete covers used as portal structures for underground access.

Equipment You'll Find at a Typical Surface Mine
In-pit belt conveyors are used to move material within a large, active mining pit area or from the pit to loading areas for further distribution within the mine. In-pit conveyors may also move mined material to portable crushing systems that reduce the size of larger rocks or minerals for easier transport.

Open-Pit Mining
Open-pit mining is a surface-mining operation, in which rocks or minerals are extracted from the Earth by creating an open hole, or pit, in the Earth’s surface. These pits are generally 1km deep beneath the Earth’s surface, and are used to exploit low-grade ore bodies.

Open Pit Mining Techniques|Surface Mines|Rock or Mineral Extraction
Open Pit Mining. Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.

Evaluation and Risk Analysis of Open-Pit Mining Operations | SpringerLink
Mining of raw materials is a process that consists of several stages. In open-pit mining, material with high compressive strength is extracted by drilling and blasting and material with low compressive strength is extracted by e. g. a bucket wheel excavator. Most important influencing factors for crusher decision are compressive strength, moisture content, capacity of crusher, abrasiveness
