The steel wire rope used by the winch of the main shaft and the winch of the belt downhill platform must comply with the provisions of the coal mine safety regulations and have the product safety certificate. The diameter of the steel wire rope must be greater than Ф Above 18mm, the winch driver and maintenance worker must check the operation of the overwinding device and depth indicator of the lifting winch before each shift, and whether the brake safety system is sensitive and reliable; Winch workers, mechanical and electrical maintenance workers, unhooking workers, and transportation team leaders should check the integrity of winch wire ropes at all levels before each shift. If they find that the worn and broken wire of the wire rope exceeds the provisions of the coal mine safety regulations, they must immediately stop lifting and replace the wire rope, and fill in the "record of lifting winch operation" and the "record of inspection on the characteristics of low wire rope noise"

3. The unhooker should carefully check the integrity and normal operation of "one slope and three gears" every shift. The car stopper of the downhill platform should be used normally, maintained and repaired frequently, and insisted on normal use; The auxiliary rope should be used normally

4. When lifting the winch in the main inclined shaft or belt downhill, the lifting winch lane should be "no pedestrians, no pedestrians". It is strictly forbidden to walk in the winch lane. All personnel in the shaft, especially those who drive the belt conveyor, should withdraw to the self-defense hole to avoid non vehicle injury. When lifting the winch, it is strictly forbidden to ride up and down the bucket

5. Before each shift, the unhooker and signalman should carefully check whether the acoustic and optical signals of the lifting system are complete and intact. For each hook, check whether the harvester bumper, the side pin of the car body and the bottom pin of the wheel are complete and intact. Check whether the links and binding pins of each car body are hung up, and whether the hanging buttons and binding pins are tied in place. Only after ensuring safety can the car body be lifted and released. When the car body is running on the winch Road, the track goes down the mountain lane Personnel such as the track downhill parking lot shall immediately hide in the self-defense barrel. It is strictly prohibited to do any work in these tunnels during lifting and placing, and together with the platform hook workers, they shall guard at both ends of the winch lane, and be responsible for stopping other people from walking up and down

6. The inspection and maintenance of the belt conveyor should be strengthened. It is strictly forbidden for the people who open the belt conveyor to doze and sleep during work. The operation of all parts of the belt conveyor should be checked frequently, and the operation of the belt conveyor should be observed at any time. If abnormal conditions are found, the belt conveyor should be shut down immediately for treatment. When the belt carrier roller should be replaced, and there are large pieces of coal and gangue stuck on the belt carrier and pressing edge, or other faults need to be handled, There must be more than two people and stop the belt conveyor before handling. When the main inclined shaft track winch is lifted, the belt conveyor operator should hide in the refuge chamber or self-defense chamber to prevent flying car loading

7. When it is necessary to transport extra long materials such as rails and pipelines through the main inclined shaft, it can only be transported manually, and it is strictly prohibited to use tramcars or material racks to lift and transport by winches. When manually transporting rails and pipelines, the following provisions shall be followed:

○ 1 pedestrians or others are strictly prohibited from doing other work in the shaft. All personnel should hide in the self-defense cave to ensure safety before manual handling

○ 2 when manually transporting the rail or pipe in the inclined shaft, the rail or pipe shall be lifted or parked with unified force, slowly lifted or lowered, and the person lifting the rail or pipe above or below shall walk slowly. The person lifting the rail or pipe above or below shall not suddenly put down one end of the rail or pipe on the way or throw away the rail or pipe with force to prevent the rail or pipe from flying away and hurting people. It is strictly forbidden for someone to directly lift the end of the rail or pipe, To prevent the rail or pipe from swinging and penetrating, so that the end will hurt people. When lifting the pipe, personnel should stick the pipe at a place more than 1.5 meters away from the end. Before handling the rail or pipe, first bind the upper end of the rail or pipe with thick hemp rope at the slope change place, so that the rail or pipe can be temporarily parked during handling. The other end of the rope should be fixed to control the rail or pipe to prevent it from flying down the inclined shaft

○ 3 it is strictly prohibited to automatically slide the rail or pipe down the main inclined shaft floor and track to prevent the rail or pipe from sliding down the mountain and hurting people

(II) safety technical measures for the transportation system of the auxiliary inclined shaft and the track downhill Lane

1. The auxiliary shaft winch and the track downhill platform winch must comply with the requirements of the coal mine safety code and the Qingshan coal mine safety monograph, and the installation must be firm and reliable. The wellhead of the auxiliary inclined shaft, the shaft of the auxiliary inclined shaft, the upper platform of the track downhill lane, the inclined groove of the bottom parking lot and the inclined groove of the intermediate dump must be installed with car blockers and anti sports car devices, At the intersection of the track downhill and the pipe sub road of the water pump house, a car stopper and anti sports car device shall be installed, and it shall be closed for a long time in the normal working state, unless the water pump house needs to be lifted for transportation, it can be temporarily opened, and it shall be closed in time if it does not lift. At the middle of the auxiliary inclined shaft downhill (at the intersection with the central centralized water bunker Lane), the car stopper and anti sports car device shall be installed 15 meters above the 11.4 winch and near the slope change point of the central parking lot. The car stopper and release gate shall be installed 15 meters above the 11.4 winch installed at the intersection of the auxiliary inclined shaft and the track downhill platform to prevent the flying car from rushing to the track downhill platform during the lifting and transportation of the auxiliary inclined shaft.
