Texto original en inglés de la MSHA

1. The mine operator failed to prevent miners from being exposed to unsupported roof. The roof bolting machine operators were allowed to position themselves in front of the machine’s drill mast at the ATRS, while installing resin glue and steel bolts into the rib. This practice exposed the miners to unsupported roof during the installation of rib bolts. The mine operator had removed the hydraulic drill guides provided by the roof bolting machine manufacturer and did not provide the recommended resin insertion tools to assist miners in angle or rib bolting. The roof bolting machine operators had not been trained in the use of the resin insertion devices, as required by the manufacturer.
