Safety knowledge of underground workers (coal mines)

There are two main mining methods for coal mines, one is underground mining and the other is open-pit mining. For deep buried deposits, underground mining is generally used. Underground mining has its special operational characteristics, mainly: poor working environment, small space; varied geological conditions, often subject to roof, mine dust, water, fire, etc. The threat of disasters; complex production processes and high labor intensity. Therefore, the underground workers must master certain safety knowledge of underground operations to ensure safety.

First, preparation before going down the well

1. The person in the well is in front of the well, and must have a good rest and rest, and it is strictly forbidden to drink alcohol in front of the well.

2, wear a helmet, overalls and rubber shoes in front of the well, so that it is neat and tidy; it is best to wear a towel on the neck, which can wipe the sweat, but also prevent the slag from falling into the clothes, in the self-help and mutual rescue May use it.

3. Personnel personnel must carry lighting lamps such as miner's lamps with them.

4, carry sharp tools, such as tile cutters, axes, saws, etc. must be sheathed or loaded with tool bags to prevent injury.
5. It is necessary to abide by the registration system for entry and registration, and the registration can be followed by a well.

6. Everyone in the well must consciously attend the pre-class meeting to clarify the production tasks and safety precautions on duty to prevent accidents.

7. Accept pre-job training and obtain a safety qualification certificate. Everyone working underground must be familiar with the disaster avoidance routes of various disaster situations at their workplace.

8. Understand the safety conditions of the route passing through the well and the safety conditions of the working environment and the safe escape route and method under emergency conditions.

Second, ride cages and people

The cage is a special equipment for transporting people to the upper and lower wells and lifting ore, materials and equipment. It is the key equipment to ensure the normal production of mines and safe entry and exit of personnel. Underground personnel must comply with the following regulations:

1. When the crew of the upper and lower wells ride on the cages, they must abide by the relevant regulations or put the instructions of the tankers up and down in order, and must not be crowded or beaten. At any time, without the permission of the wellhead management or the tanker, it is not allowed to enter or exit the cage, especially after the lifting signal is sent, or the cage is not stopped, do not compete for the upper and lower. Each tank must not be overrun.

2. After entering the cage, the tank door or can curtain must be closed. The person should stand firmly, the legs should be slightly bent, and the hand should hold the handrail. Do not put your head and hands, feet or tools to the outside of the cage. Do not play in the cage, or throw anything into the wellbore, otherwise it will cause an accident.

3. It is strictly forbidden to take a layer of cages with people and materials or mine cars. In cages containing blasting materials, other personnel shall not be accompanied by blasters or escorts.

4. It is not allowed to take non-passenger vehicles in the underground. It is strictly forbidden to take the buckets, mine cars and other non-loading tools to go up and down the well.

5, when riding a car, you must listen to the command of the passengers, do not get crowded. You must close the door or hang the protective chain before driving. The human body and the tools and parts it carries are strictly prohibited from being exposed outside the vehicle, and it is not allowed to touch the overhead line to prevent electric shock.

6. When the train is running and has not stopped, it is strictly forbidden to get on or off or stand in the car.

7. It is strictly forbidden to ride on the locomotive head or between any two compartments. It is strictly forbidden to ride over, and it is strictly forbidden to drive, jump and take the mine.

8. When the vehicle is found to be in the lane, it must immediately send a stop signal to the driver.

9. When the long-distance flat or underground roadway is used for people's vehicles, the appearance of the probe is strictly prohibited. Once the car is down, it is not allowed to jump out of the car.

Third, walking underground

The underground roadway is small in space, with many vehicles coming and going, and some have conveyors installed, so be sure to pay attention to safety when walking.

1. Adhere to the sidewalks of pedestrian lanes and transport lanes.

2. When walking on the roadway where the sidewalk is not wide enough, always pay attention to avoid the position of the cockroach; when the vehicle is approaching, you must enter the escaping squatting in time, and wait for the vehicle to come out later.

3. It is forbidden to hide in the middle of the non-sidewalk side and the double track of the double track roadway.

4. Do not walk in the middle of the track, nor traverse the track at random to avoid accidents. If you must cross it, you must cross it when there is no vehicle passing. Especially when crossing the wire rope, be more careful to prevent tripping or being injured by the wire rope. When the wire rope is running, it is strictly prohibited to cross the wire rope.

5. When walking in inclined shafts, it is necessary to insist that “Pedestrians do not drive, and pedestrians are not pedestrians”, and they must walk on sidewalks and must not ride on wire ropes.

6. It is not allowed to enter the unventilated roadway; all the places that have been fenced and have the “No Insider” warning sign are not allowed to enter. These places may accumulate harmful gases such as gas, and entry is very dangerous.

7. After passing the construction site, you must first say hello, and you can pass it after you agree. When passing the damper, close the door with your hand to prevent short circuit.

8. Carry long tools (such as drill pipe, spade, etc.) that you carry with you. Do not put it on your shoulders to prevent injury or injury to the overhead line.

9. No matter whether you are walking in any roadway, don't make a loud laugh, make trouble, pay attention to the vehicles and various sound and light signals at any time, listen to the signal command, and do not allow unauthorized signals.

10. Once you are lost in the underground, don't be nervous; you can find the exit according to the feng shui pipeline or the direction of the wind.

Fourth, work safety knowledge

1. Protect all kinds of safety production facilities, installations, safety signs and measurement marks. It is strictly forbidden to use equipment that is not used by oneself automatically, and undocumented persons are not allowed to engage in special operations.

2. It is not allowed to shoot and work alone in the underground, and it is not allowed to enter a remote area or a dangerous area by a single person.

3. The entry operator should master the blasting time, location, and warning range, and must evacuate the danger zone before blasting.

4. Obey the safety technical operation rules and various post safety management regulations, follow the supervision and guidance, do not violate the regulations, do not risk the operation, and the accident should be reported immediately.

5, in the event of a sudden power outage, should immediately stop working, retreat to a safe place.

6, before the work should first help the top of the question, the work should check the support situation at any time, find the top, help loose or fall off, should immediately avoid or stand in a safe place to clean up. When there is a serious threat to personal safety at the work site, the danger zone must be quickly withdrawn and reported and processed in a timely manner, with warning or signal signs set.

7, strict labor discipline, not allowed to fire in the underground to warm, loud noise, trouble, sleep and squatting. Do not smoke in the well.

8. When rest is required in the underground, you should choose a safe place with complete roof, good support, no obstruction to work, no obstacles to driving, and good ventilation. Do not rest in front of a closed wall or in a blind alley. These locations are poorly ventilated and tend to accumulate harmful gases.
