The Pillar in Mining is a fundamental concept in underground mining used to support the roof of a mine. The Pillar in Mining refers to a portion of ore or rock that is left unmined to provide structural stability. In practical mining operations, the Pillar in Mining prevents roof collapse and ensures worker safety. At MiningGyan, the Pillar in Mining is explained in a simple and practical way for students and professionals.
Pillar in Mining – Definition and Concept
The Pillar in Mining is a block of material left in place to support the overlying strata during mining. The Pillar in Mining is commonly used in room and pillar mining methods. In the Pillar in Mining system, extraction and support happen simultaneously. The size and design of the Pillar in Mining depend on depth, load, and rock strength.
