What are the preventive measures for safety accidents of mine hoisting system?

Measures to prevent mine car from falling into the well.

Let me add something.

1.( 1) Hook operators must strictly abide by the operating procedures, and the parallel doors must be closed before the cage is lifted, and the car is not allowed to be released until the position of the car stopper is restored. After the cage is installed, the signalman shall check and confirm that the vehicle has completely entered the cage before sending out the driving signal. The car stopper at the door and the car stopper in the tank are flexible and easy to use.

(2) Keep the workover equipment in good condition and reliable, and ask relevant maintenance personnel to repair it in time when problems are found. The car stopper should be interlocked with the cage stop position, and it is not allowed to operate the pusher without the training well and certificate. The harvester should be inspected, and those with unqualified height should not be used.

(3) Don't get on and load at the wellhead exit side. If necessary, measures should be formulated and approved by relevant leaders.

(4) When long materials or equipment pass through the shaft, they must be tied firmly and hung reasonably to prevent the loose buckle from falling or being scratched.

2. Measures to prevent accidents such as broken rope, overwinding, cans and stuck cans.

(1) In addition, the electromechanical department must be responsible for the installation of the overwinding height and overwinding distance of the safety device in the lifting device, as well as the use, maintenance, test, inspection and connection of the wire rope. The bell man and hook man at the upper and lower wellhead must pay attention to monitoring the cage operation and whether the wire rope is slack. When it is found that the lifting operation is abnormal, and accidents such as broken rope, overwinding and tank jamming may occur, it must be

(2) The maximum load and maximum load difference of cage and skip shall be announced at the wellhead, and overloading is prohibited to prevent overwinding caused by overloading. At the same time, the existing loading device is improved and the overweight protection is increased.

(3) In order to prevent the cage from being stuck for a short time due to the inflexible opening of the cage seat, the cage quickly slides down, resulting in a broken wire rope accident. The inspection seat must be cleaned regularly to ensure the flexibility and reliability of the tank seat, and according to the requirements of "Coal Mine Safety Regulations", a locking device must be set for the tank seat.

(4) The transportation department should keep in constant contact with the mechanical and electrical department, and arrange necessary tank stopping time to create conditions for daily inspection of lifting containers, connecting devices, fall arresters, tank ears, tank guides, car stops, seats, rocking tables, loading and unloading equipment, crown blocks, wire ropes and lifting winches, so as to deal with problems immediately.
