Common sense knowledge about mine flood prevention and fighting

1. What are some tips on flood prevention?

1. After receiving instructions or notifications from superiors, the leading group immediately enters a war-fighting state, releases relevant news and warnings in accordance with the law, and comprehensively organizes various flood prevention measures Flood relief work. All relevant organizations are ready to carry out flood prevention and relief tasks at any time. (Responsible leader: Lin Chong)

2. Organize relevant personnel to conduct a comprehensive inspection of the affiliated buildings, block and close dangerous places, and stop various indoor large-scale activities. (Responsible person: Wu Song)

3. Strengthen publicity and education among teachers and students, and do a good job in stabilizing the ideological stability of teachers, students, and parents.

And do a good job in guiding students and evacuating students to safe places

4. Teams at all levels, under the unified organization and command of the principal’s office, quickly organize emergency rescue and disaster relief at the same level, and take all measures We must use necessary means to organize all forces to comprehensively carry out flood control and flood control work, and minimize the losses caused by flood control and flood control.

2. How to prevent floods and droughts

Artificial rainfall and drought causes study the influence of geomagnetism on weather. I have seen the use of polar Articles about low frequency affecting the weather. This aspect currently needs research. This is a discovery by Russia and the Americans, which proves the connection between weather and extremely low frequency. If you are doing this, you can do research and use the extremely low frequency principle to carry out artificial rainfall, etc. , of course if you have the ability.

If you want to resist drought, you can refer to the following. Charcoal may be able to absorb the water needed by crops. You can first set up an experimental field and use charcoal to absorb water and easily become damp. It can be combined with the soil because of the presence of charcoal. The water rate is greater than the water storage rate of the soil, so it can store water for crops. In order to reduce costs, charcoal materials can be processed from corn stalks and other materials. You can conduct an experiment first to benefit your neighbors.

3. Knowledge on disaster prevention and reduction

"Ten Golden Rules for Protecting Life"

Human life must be protected, and the ten rules must be remembered once a disaster occurs. When doing so, be aware of the situation and apply it in a timely manner.

1. Earthquake: If you encounter an earthquake, take shelter first. Find a gap under the table or bed, lean against a corner and bend your body. Seize the opportunity to escape, stay away from all buildings, and squat in the open area during aftershocks.

2. Fire: When a fire breaks out, if you are afraid of smoke, you will cover your nose and mouth with a wet towel, and your body will catch fire and roll to the ground. If you don’t take the elevator, run down, slide down the rope from the balcony, and blindly jump off the building will hurt your body.

3. Flood: The flood is fierce. It is difficult to stay at high places. You cannot stay on the roof of an earthen house. A raft can be tied to the bed and table. A lifeline can be tied to a big tree. Prepare food, flashlight, and wear warm clothes to survive the danger.

4. Typhoon: When a typhoon comes, listen to the forecast, strengthen the dams and waterways, repair the gas circuits, make temporary buildings secure, anchor the ship deep in the port, and reduce travel to check for signals.

5. Debris flow: When it rains heavily and mudslides occur, the dangerous place is downstream. When escaping, don’t walk along the bottom of the ditch. Climb up the mountain quickly. Do not choose a ditch when camping in the wild. When entering the mountain, you must pay attention to the weather.

6. Lightning strikes: On cloudy and rainy days, thunder and lightning will occur. Take shelter from the rain and do not stand under a tree. Keep away from iron towers and poles. Take precautions against thunder at home. Close the doors and windows and turn off the power supply to avoid thunder and fire from escaping in the house.

7. Blizzard: On a blizzard day, when jogging, don’t stop with your back to the wind. Your body will be frozen and unconscious. You must not bake it with fire. The ice and snow will wash away the blood circulation, and it will heal slowly if it warms up.

8. Tornado: Once a tornado or strong storm strikes, you should enter the cellar, stay indoors away from the doors and windows, turn off all power and water sources, and lie down in low-lying areas outdoors. The inside of the car is unreliable.

9. Epidemic: Don’t be paralyzed about the epidemic, and be careful to prevent infection. Isolate patients immediately when they are found, ventilate and disinfect tableware, seek medical treatment as soon as possible if infected, and avoid going to public places.

10. Chemical protection: Chemicals are dangerous. Do not pick up abandoned items. Prevent fireworks from burning poisonous gas. Call the police to indicate the accident. Don’t watch when there is a transportation leak. Stay away from people in the limelight.

Human life is more important than mountains. Prevent disasters and avoid danger before they happen. Master the skills and practice them frequently. I wish everyone a safe life! I wish everyone a safe life! !

4. Mine safety knowledge

1 Contents of safety inspection: "Coal Mine Safety Regulations" and "Henan Province Coal Mine Safety Production Basic Standards".

2 Coal mines must promptly fill in drawings that reflect the actual situation 1. Mine geology and hydrogeology map 2. Top and bottom comparison map 3. Roadway layout map 4. Excavation engineering plan 5. Ventilation system map 6. Underground transportation system map 7 Safety monitoring equipment floor plan diagram 8 Pipeline system diagrams for drainage, dust prevention, fire prevention, grouting, air pressure, filling, gas pumping, etc. 9 Underground communication system diagram 10 Up and down power distribution system diagram and underground electrical layout diagram 11 Underground disaster avoidance route map 3 Well entry requirements: Personnel entering the well must wear a safety helmet and carry a self-rescuer and miner's lamp with them. Tobacco and ignition items are strictly prohibited. It is strictly forbidden to wear chemical fiber clothes, it is strictly forbidden to drink alcohol before entering the well, and mentally ill people are strictly prohibited to enter the well.

Coal mining enterprises must establish a system for physical examination and well inventory. 4 Five natural disasters: gas, coal dust, floods, fires, and roofs.

5 One pass and three defenses: One pass refers to ventilation, fire prevention, gas prevention and coal dust prevention. 6. What is mine gas? What are its main components: Mine gas is a general term for various harmful gases released from coal seams, rock formations and goafs during the production process of coal mines.

Mainly include biogas (SH4) carbon dioxide (CO2) carbon monoxide (CO) sulfur dioxide (SO2) nitrogen dioxide (NO2) hydrogen sulfide (H2S). 7 Properties of carbon monoxide: Carbon monoxide is a colorless, odorless gas, lighter than air with a specific gravity of 0.97. It is generally combustible and explosive in the upper and middle parts of the roadway. The "Regulations" stipulates that the concentration of carbon monoxide in the mine cannot exceed 0.00248 gas explosion. Three elements: the gas content is 5------16, and there is a detonation fire source of 650--750 degrees.

Oxygen content not less than 12. The explosion is most powerful when the biogas concentration reaches 9.5.

9 Three violations refer to: illegal operation, illegal command, and violation of labor discipline. The hazards of 11-watt explosions: 1. After a gas explosion, it not only causes a large number of casualties, but also produces high-temperature, high-pressure gas and damages underground facilities.

2. After the gas explodes, the temperature at the explosion point drops rapidly and the air becomes thinner, forming a reverse impact force and increasing its explosiveness. 3. After a gas explosion, a large amount of oxygen participates in the combustion, resulting in low oxygen content. At the same time, due to the increase in carbon monoxide, a large number of casualties occur.

4. The gas explosion produces high temperature (1850 degrees) and causes fire. 5 After the gas explosion, communication facilities and ventilation systems were destroyed, causing difficulties in mine rescue.

10. Three inspections for one gun: before charging, before firing, and after firing. 11 Wind measurement station requirements and standards: It must be located in a straight lane, its length must not be less than 4 meters, and there are no turns or other obstacles within 10 meters in front and back. The wind measurement station should have a record plate and number.

A wind measuring station is set up in the wooden support tunnel to ensure close contact with the wind roof, so that all the air volume in the tunnel can pass through. 12 Three specialties and two locks: Three specialties refer to special transformers, special switches and special lines.

Second lock: refers to wind power lock and gas power lock. 13 The "three counterparts" of gas inspection refer to: the record plate of the gas inspection location, the inspection manual carried by the gas inspector and the gas ledger on the ground.

Main content: Inspection location and name of inspector, inspection date, shift and specific time of each inspection, and inspection results. 14What is an independent ventilation system? The return air flow from the mining area or mining working face directly enters the return air tunnel and no longer enters the ventilation system of other mining face working faces or other wind-using locations.

15 Series ventilation: The ventilation method in which the air returns from the mining and excavation working face or chamber and then enters other mining and excavation working faces or chambers. The hazard is: the air in the connected mining and excavation working surfaces or chambers cannot be guaranteed.

2. Once a disaster occurs in the front mining working face or chamber, it will affect the connected working faces and expand the scope of the disaster area.

The regulations stipulate that series ventilation cannot be used more than twice with the approval of the mine director and chief technical engineer, and the gas concentration in the series air cannot exceed 0.516. Circulating air: Circulating air generally occurs in local ventilation systems, that is, in part or all of the air flow. Then enter the same incoming air flow.

Hazards: The wind from the excavation working face repeatedly returns to the excavation working face, and the concentration of toxic and harmful gases and dust will become larger and larger. Not only will the working environment deteriorate, but more importantly, due to the increasing gas concentration in the wind flow, It is very easy to cause gas accidents. The "Regulations" stipulate that local fans and starting devices for local fans must be installed in the air inlet tunnel, and the distance from the air outlet should not be less than 10 meters.

17. Upward ventilation and downward ventilation: For shafts or inclined lanes, the ventilation method in which the air flow flows upward is called upward ventilation. On the contrary, the ventilation method in which the air flow flows downward is called downward ventilation. 18 The specific content of "three nos, four yeses, two completes, three completes, and two insistences" for underground power supply are: three nos: organic chicken feet, no sheep tails, and no obvious joints.

Four: There are overcurrent and leakage protection devices, screws and spring washers, seals and baffles, and grounding devices. Three completes: complete protective devices, complete insulation equipment, and complete drawings and materials.

Three insistences: insist on using leak detection relays, insisting on using coal electric drills, insisting on comprehensive protection of lighting and signals, and insisting on using gas power and wind power blocking. 19 Requirements for the management and use of miner's lamps: 1. The total number of intact miner's lamps in each mine should be at least more than the number of people who regularly use the lamps. 102. Each lamp should have a number, and those who frequently use miner's lamps must have a dedicated person with a dedicated lamp.

3. The miner's lamp should be in good condition. If there is battery leakage, insufficient brightness, damaged wires, poor lamp lock, loose lamp head ring, broken glass, etc., it is strictly prohibited to distribute it. The miner's lamp issued can be used continuously for at least 11 hours. . 4. Lamp room staff must report the list of personnel who have not returned lamps to the mine dispatching room two hours after each shift.

20. What are the signs before the mine is flooded? There may also be various symptoms such as sweating, redness, water squealing, cold air, fog, and water leakage before water leakage occurs, the bottom plate bulges, the roof is dripping with water, there is silt in the rock, and pieces of roof collapse. 21 Principles of water exploration and release: State-owned: if in doubt, explore first, explore first before mining; townships: explore first before digging, explore first before mining.

22. Requirements for lumber yard: The distance between the lumber yard and the wind shaft should not be less than 80 meters. 23 Ground fire protection pool regulations: Ground fire protection pools must maintain a water volume of no less than 200 cubic meters.

No fireworks or stoves can be used for heating in well 24 and within 20 meters of the ventilation room. 25. Should the following regulations be observed when dealing with blind guns? Handling blind guns must be carried out under the direct guidance of the team leader and should be completed during the shift.

If the work cannot be completed on the shift, the blaster must hand it over clearly to the blaster on the same shift at the scene. It is strictly prohibited to carry out work unrelated to the treatment of blind cannons at this location before the treatment of blind cannons is completed.

26. What are the rules for blasters?

5. Coal Mine Flood Control and Drainage Measures

In order to safely prevent floods, Zaoquan Coal Mine has taken multiple measures and struck hard, adopting the "four-in-place" approach of technical defense, human defense, physical defense and prevention. "Measures to effectively strengthen the "three preventions" work during the rainy season to ensure that mines are prepared for disasters.

Technical defense is in place. Improve prediction, early warning, prevention and disposal mechanisms, and improve the information transmission mechanism for production shutdown and evacuation to prepare for safe evacuation in emergencies; carefully carry out inspection, testing and maintenance of pipelines, power supply systems, etc., and clear water before the flood season Storehouses, dredge underground ditches and ground flood discharge ditches to ensure smooth and reliable drainage systems; actively carry out geological prediction and forecasting, clearly understand underground water-bearing areas, conduct regular measurement and analysis, and make sure to investigate when in doubt.

Personal defense is in place. Early arrangements, early prevention, and early implementation of the "three prevention" work in the rainy season, the establishment of a "three prevention" work leading group and an emergency rescue headquarters in the rainy season, the formation of a rescue and disaster relief commando team, and the implementation of a 24-hour flood prevention duty system to promptly detect and deal with hidden dangers; equipped with Special personnel are assigned to inspect and debug the flood control facilities, carefully inspect the 980m well bottom water silo, clear the silo in a timely manner, and regularly check the drainage capacity of the underground main drainage pump.

Physical defense is in place.

In view of the actual impact of the rainy season on the supply of yellow sand, we actively reserve flood control yellow sand; in accordance with the requirements of the flood control plan, we prepare sufficient emergency supplies such as shovels, lifting baskets, woven bags, and raincoats; in the main inclined shaft, auxiliary inclined shaft and substation Prepare sufficient flood prevention sandbags and other blocking materials in key areas.

Take precautions. Comprehensively analyze and troubleshoot existing problems in mine power supply, drainage, lightning protection and other systems, conduct ground resistance testing and line maintenance, reinforcement and cleaning of high-rise buildings, substations, power supply communication lines, and lightning protection facilities to ensure lightning protection Prevent electricity; focus on water storage excavation, water pump maintenance, power supply line maintenance, electrical protection preventive setting experiments, etc. to ensure smooth drainage and intact power supply equipment, and truly make preparations for "flood prevention, flood prevention, and emergency rescue"
