What is meant by "Squeeze" in mining terminology?

In mining terminology, "Squeeze" refers specifically to the situation where excess weight on coal pillars leads to their failure. This failure can occur when the weight of the overlying rock becomes too great for the pillars to support, resulting in a collapse or significant deformation. Understanding this concept is crucial for mine safety, as it highlights the importance of proper pillar design and the need for monitoring and management of loads that coal pillars carry.

The term is distinct and primarily used to describe the physical stress induced by external forces on the structural integrity of the mine. This has implications for operational practices, maintenance, and emergency preparedness within mining operations. Being aware of the risks associated with pillar squeeze can help mining personnel make informed decisions regarding extraction methods and pillar strength.

Recognizing and managing the potential for squeeze is essential in preventing accidents and ensuring the safety of miners working in the vicinity. Therefore, this understanding plays a critical role in effective mine management and planning.
