HUNTINGTON, Utah (CNN) -- Rescue workers early Saturday punched a second, wider hole through Utah's Crandall Canyon mine, breaking into a cavity where they believe six workers have been trapped since Monday, the mine's owner, Bob Murray, said.

Murray Energy CEO Bob Murray, center, investigates the mine collapse Saturday morning with others.

Next, officials plan to drop a video camera inside the hole, which is about 8½ inches wide and more than 1,800 feet deep.

The camera will let authorities see for about 100 feet and provide "significant detail that will give us additional information about conditions underground," said Richard Stickler, assistant secretary of the Department of Labor for mine safety and health.

Rescue workers were removing the heavy steel drill bit and planned to send the camera into the mine shaft later Saturday.

"The activity is of a very fast pace, but progress is way too slow for me, and I think for anyone, but it's not because of effort," Murray, president and CEO of Murray Energy Corp., told reporters.
