This application discloses a hoisting winch for emergency recovery operations of manned submersibles, which includes a hoisting winch assembly and a hydraulic motor. The hoisting winch assembly includes: an annular boss is arranged on the drum, and a second A bearing cover plate, a blind hole is arranged above the first bearing cover plate; multiple thin-walled bearings are arranged side by side, the bearing inner ring of the thin-walled bearing is installed above the annular boss, and the bearing outer ring of the thin-walled bearing is installed on the pulley Below, the connection between the inner ring of the thin-walled bearing and the annular boss is a single-side shoulder positioning method; the left side of the pulley is provided with a threaded long hole, and a set screw pin is installed in the threaded long hole. After the fixed screw pin is screwed out of the blind hole, the pulley can rotate on the reel; the second bearing cover plate is installed on the right side of the pulley to limit the thin-walled bearing. Through the technical solution in this application, the pulleys used for emergency recovery are integrated on the reel of the existing hoisting winch, so as to improve the safety and efficiency of emergency recovery of the submersible.

An underground working personnel emergency rescue guiding system and a guiding method are provided, so safety management personnel can timely learn about underground personnel distribution conditions, early warning can be timely send to underground people and an effectively escape route can be timely provided for underground personnel when danger happens, thus effectively reducing personnel casualty and economic losses, and improving mine enterprise safety production level; the guiding system comprises a host computer, a fiber communication device, a communication substation, an information miner light, an audible-visual annunciator, an escape guiding screen and a power supply; the guiding method comprises the following steps: the host computer receives people monitoring data from the communication substation through the fiber communication device, and sends short message data, alarm data and escape guiding data to the communication substation; the communication substation sends the short message data to the information miner light, and respectively transfers acousto-optic alarm data and escape guiding data to the audible-visual annunciator and escape guiding screen; the underground working personnel wear the information miner light, send communication codes identifying IDs to the communication substation, and receive the early warning information and the guiding route from the communication substation.
