What is the acceptable distance for starting boreholes from any uninspected abandoned workings?

The acceptable distance for starting boreholes from any uninspected abandoned workings is established for safety reasons in mining operations. This distance is set to prevent any potential hazards that might arise from the close proximity to abandoned sites, which can include risks of collapse, gas accumulation, or unforeseen geological conditions.

Choosing a distance of 200 feet allows for a buffer zone that minimizes the risks associated with uninspected abandoned workings. This distance ensures that drilling activities do not compromise the integrity of the ground surrounding these areas and provides an added layer of safety for workers and equipment involved in the operation.

It is critical to adhere to these standards in order to promote safe mining practices and reduce the likelihood of accidents during drilling operations.
