Roof Bolting
Roof bolting is a critical safety practice in underground mining where workers secure the roof of mine tunnels to prevent cave-ins. It involves drilling holes into the mine's ceiling and installing long metal bolts to hold rock layers together, much like how screws hold pieces of wood together. This is one of the most important jobs in mining because it helps keep miners safe by preventing rocks from falling. Workers who do this job are called roof bolters or roof bolting operators, and they use specialized machines called roof bolters to perform this work. This is a required skill in underground mining, particularly in coal mines, where maintaining stable tunnels is essential for safe operations.
