MSHA Part 48 Underground Mining Refresher

Online Training Certification Course

From the highest rated and most trusted online training company - since 2008.


Underground mining and the surface areas of underground mines present numerous health and safety hazards. Even experienced miners require MSHA Part 48 refresher training to meet regulatory requirements and stay safe. This online certification course presents an overview of Part 48 refresher requirements. It covers basic safety training regulations for underground mine work, emergency response procedures, and how to recognize and avoid mining hazards.

In addition, this MSHA underground refresher course covers the rights and responsibilities of miners.

This course is for:
This MSHA underground mining training is designed to retrain experienced miners who have at least one year's experience working in a mine site.

Case Study: On May 20, 2006, five coal miners were killed and one was injured as a result of an underground explosion which occurred when two miners carrying oxygen-acetylene torches rode down a return airway in order to perform seal maintenance. The explosion, originally caused by the ignition of methane gas, damaged the seals. Coal dust in the sealed areas then ignited and caused further damage, resulting in the death and injury of the other four miners.

Key Takeaways: To prevent accidents like this, always apply rock dust liberally and frequently, and be sure to clean up all loose coal, coal dust, and other combustible materials. It is also necessary to maintain sufficient ventilation and test frequently for dangerous gases.
