MSHA Part 48 Underground Mining Refresher Overview
Online Training & Recertification Course
from the highest rated and most trusted online training company - since 2008.
This course is designed to help you achieve a greater awareness of the health and safety hazards inherent in underground mining and the surface areas of underground mines. The course aims to provide experienced miners with greater understanding of underground mine health and safety hazards, the regulations that accompany work at a mine, and the rights of miners.
One way that MSHA tries to keep underground miners safe is by requiring annual refresher training in accordance with 30 CFR § 48.8 and § 48.28. This training must cover health and safety factors, prevalent hazards, and emergency procedures.
To be MSHA compliant your company must have a training plan that is approved by MSHA and administered by a competent person. Your company can use this or any of our courses as part of that plan.
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.
Each miner shall receive a minimum of 8 hours of annual refresher training as prescribed in this section.
The annual refresher training program for all miners shall include the following courses of instruction:

Roof or ground control, ventilation, emergency evacuation and firefighting plans. The course shall include a review of roof or ground control plans in effect at the mine and the procedures for maintaining and controlling ventilation. In addition, for underground coal mines, except for miners who receive this training under 30 CFR 75.1504, the course shall include a review of the emergency evacuation and firefighting program of instruction in effect at the mine.
First aid. The course shall include a review of first aid methods acceptable to MSHA.
Electrical hazards. The course shall include recognition and avoidance of electrical hazards.
Prevention of accidents. The course shall include a review of accidents and causes of accidents, and instruction in accident prevention in the work environment.

Such other courses as may be required by the District Manager based on circumstances and conditions at the mine.
Refresher training may include other health and safety subjects that are relevant to mining operations at the mine. Recommended subjects include, but are not limited to, information about the physical and health hazards of chemicals in the miner's work area, the protective measures a miner can take against these hazards, and the contents of the mine's HAZCOM program.
Where annual refresher training is conducted periodically, such sessions shall not be less than 30 minutes of actual instruction time and the miners shall be notified that the session is part of annual refresher training.
