On September 24, 2008, at 18:15, during the process of ore ores upgrading, the winch driver, after receiving the execution signal from the ground signal operator, started the hoist. After nearly 1m of operation, it received a stop signal from underground signal workers and stopped immediately. At this moment, a hooked worker in the mine was caused to hit the ceiling. The hospital diagnosis, less than minor injuries, but it is very terrible thought. Analysis of the causes of the accident In the last cycle of ascension, when the downhole signal worker issued a request signal to the ground, the winch driver, only observing by the monitor if it has not yet received the signal from the terrestrial signal operator, thought that it had the operating conditions, It will start the operation without permission, causing the ground signal station to request the loop
