What is the minimum accepted distance between the remote control miner operator and unsupported roof during extended length cuts?

The correct answer is that the minimum accepted distance between the remote control miner operator and unsupported roof during extended length cuts is a minimum of 2 rows of roof bolts. This requirement is rooted in safety protocols designed to protect miners from the risks associated with roof falls, which can occur in underground mining operations.

Ensuring that there is a minimum of two rows of roof bolts in place helps to provide adequate support to the mine roof, reducing the likelihood of collapse. Roof bolts are an essential component of ground control systems, and their proper installation and numbering are critical for maintaining the structural integrity of the mine.

By adhering to this safety distance, operators can minimize their exposure to potential hazards while performing their tasks. It reflects best practices within the industry and aligns with regulatory standards aimed at ensuring miner safety.
