What year is regarded as the deadliest year in the history of coal mining?
Correct Answer
C. 1907
Explanation
In 1907, the deadliest year in the history of coal mining occurred. This year is infamous for the Monongah mining disaster, which took place in West Virginia, USA. The disaster resulted in the deaths of 362 miners, making it the worst coal mining accident in American history. The explosion was caused by a combination of factors, including a buildup of coal dust and methane gas. The tragedy led to significant changes in mining safety regulations and practices to prevent similar incidents in the future.

Which of the following is not one of the important things to consider when looking at ground control?
Correct Answer
B. Leveled Ground
Explanation
When looking at ground control, leveled ground is an important factor to consider. It ensures stability and prevents any unevenness or slopes that could lead to accidents or structural damage. Pillar design, roof supports, and horizontal stress support are also crucial considerations when assessing ground control as they contribute to the overall strength and safety of the structure. Therefore, the correct answer is "Leveled Ground" because it is indeed an important aspect to consider when looking at ground control.
3.
What is the full meaning of the acronym ''SLAM'' used in risk management in mining operations?
Correct Answer
D. Stop Look Assess ManageÂ
Explanation
SLAM stands for Stop Look Assess Manage in the context of risk management in mining operations. This acronym represents a systematic approach to managing risks in mining operations. It emphasizes the importance of stopping to evaluate the situation, looking for potential hazards, assessing the risks involved, and implementing appropriate measures to manage those risks effectively. This approach helps to ensure the safety of workers and minimize potential accidents or incidents in mining operations.
4.
Which of the following is the most commonly needed respiratory protection in mining operations?
Correct Answer
B. Dust protection
Explanation
In mining operations, the most commonly needed respiratory protection is dust protection. Mining activities often generate a significant amount of dust, which can contain harmful particles such as silica or coal dust. Breathing in this dust over a prolonged period can lead to respiratory diseases such as silicosis or black lung. Therefore, wearing respiratory protection specifically designed to filter out dust particles is crucial in ensuring the safety and health of miners.
5.
Which of the following are not worn frequently below ground unless a particular operation poses a danger of chemical splash?
Correct Answer
A. Goggles
Explanation
Goggles are not worn frequently below ground unless a particular operation poses a danger of chemical splash. This suggests that goggles are not commonly used underground unless there is a specific risk of chemical splashes. Other protective equipment such as respirators, face masks, and cap lamps may be more commonly used in underground environments for different purposes.
6.
What is the full meaning of the acronym 'SMART' used for risk management during mining operations?
Correct Answer
B. Stop Measure Act Review Train
Explanation
The correct answer is "Stop Measure Act Review Train". This acronym, SMART, is used in risk management during mining operations. It emphasizes the importance of stopping to assess the situation, measuring the risks involved, taking appropriate action, reviewing the effectiveness of the actions taken, and continuously training and improving the risk management processes.
7.
Which type of battery still predominates in most mining applications and operations?
Correct Answer
A. Lead acid battery
Explanation
Lead acid batteries still predominates in most mining applications and operations due to their reliability, durability, and cost-effectiveness. These batteries have a long cycle life and can withstand harsh operating conditions, making them ideal for the demanding environments of mining operations. Additionally, lead acid batteries have a lower upfront cost compared to other battery types, making them a preferred choice for mining companies looking to minimize expenses.
8.
When was the Fair Labor Standards Act passed by Congress, which prohibits the use of workers under 18 for occupations that were deemed dangerous?
Correct Answer
C. 1938
Explanation
The Fair Labor Standards Act was passed by Congress in 1938. This act prohibits the use of workers under 18 for occupations that were considered dangerous.
9.
Which of the following is not an eye and face protection equipment?
Correct Answer
D. Cap lamp
Explanation
A cap lamp is not an eye and face protection equipment because it is primarily used for providing illumination in dark environments such as mines. It is designed to be worn on the head and does not offer any form of protection for the eyes or face. Safety spectacles, goggles, and face shields, on the other hand, are specifically designed to protect the eyes and face from potential hazards such as flying debris, chemicals, or intense light.
10.
Which of the following is not one of the most important things that should be included when documenting safety procedures?
Correct Answer
A. Who is charge of the safety procedures
Explanation
The question asks for something that should not be included when documenting safety procedures. The answer "Who is in charge of the safety procedures" is incorrect because it is one of the most important things that should be included. Knowing who is responsible for the safety procedures is crucial for effective implementation and accountability.
