An underground-surface mine which employs a total of not more than 50 to 75 employees is classified as ____.

In the context of underground-surface mines, classification systems are often established to categorize mines based on size and the number of employees. A mine that employs a total of not more than 50 to 75 employees typically falls into a specific category that reflects its operational scale, safety requirements, and regulations.

The classification of such a mine as Class C indicates that it is a smaller operation, which may have different safety standards and regulatory obligations compared to larger mines. These classifications are crucial for implementing appropriate safety measures, monitoring practices, and ensuring compliance with mining regulations that are tailored to the scale and complexity of the operation.

Understanding these classifications helps ensure that all mines operate under suitable conditions that account for the number of employees and the potential risks associated with mining activities in those environments. This system fosters enhanced safety and minimizes hazards in the mining industry by recognizing the varying needs of mines based on their size and workforce.
