How many working days in advance must the operator notify the district inspector prior to the commencement of first pillaring?

The requirement for notifying the district inspector prior to the commencement of first pillaring is rooted in regulations that ensure safety and compliance in mining operations. The correct answer, which states that the operator must notify the district inspector 5 working days in advance, is designed to provide adequate time for the inspector to prepare for and conduct necessary assessments. This lead time also allows for any potential safety questions or concerns to be addressed before operations begin.

Five working days is a standard timeframe that balances the need for operational efficiency with the imperative of ensuring safety standards are met. This advance notice serves multiple purposes, including enabling the inspector to review relevant documents, conduct site assessments if necessary, and plan for their schedule around the inspection. In the context of mining operations, such notification practices are crucial for preventing accidents and ensuring that all legal and safety obligations are fulfilled before any significant mining activities, such as first pillaring, take place.
