Texto original en inglés de la MSHA
On April 11, 2023, at approximately 10:35 a.m., Blaik Nutting, a 26 year-old stope miner with over five years of experience, died when a 20 to 25-ton rock from the hanging wall fell and struck him. The accident occurred because the mine operator did not: 1) design, install, and maintain ground support to control the ground in places where miners work or travel to perform their assigned tasks, and 2) conduct adequate ground condition examinations in areas where work was to be performed.
-
The mine operator did not design, install, and maintain ground support to control the ground in places where miners work or travel to perform their assigned tasks.
Acción correctiva: The mine operator updated the ground control plan to include ground support in narrow stope mining. The revised ground control plan contains additional information about proper installation, spacing, and maintenance of ground support bolts and stulls. The mine operator revised their training plan and trained miners on these changes.
-
The mine operator did not conduct adequate ground condition examinations and testing in areas where work was to be performed.
Acción correctiva: The mine operator retrained their designated persons on what constitutes proper and thorough ground condition examinations and testing.
