Coal mine fire control knowledge and safety common sense
Management Regulations on Preventing Spontaneous Combustion of Coal and Setting Fire Control Facilities
1. When designing the mining area or working face, the production technology department must seriously consider the fire prevention problem and follow the following principles:
(1). Try to adopt mining procedures that can avoid excessive cutting of coal pillars in the mine.
[2]. Leave enough protection coal pillar, adopt the management of mining area separation, and avoid intercommunication between mining areas.
(3) Reasonably arrange ventilation facilities and try to avoid mines and mined-out areas.
(4). Try to reduce the number of coal wells crossing coal seams and try to avoid the emergence of regional corner ventilation systems.
5]. Realize centralized production, shorten the production front as far as possible, and gradually shrink and close the old mining area.
2. Using gob-side entry retaining mining method to promote the working face, the ventilation department should formulate special fire prevention measures and submit them to the chief engineer of the mine for approval.
3. The coal mining face must be operated in strict accordance with the requirements of operation procedures, and coal must not be thrown into the goaf more or less. Mining height must be strictly controlled, leaving no top coal or bottom coal. The floating coal at the end and working face should be cleaned up and not left in the goaf.
4. Strengthen roadway support and try to avoid roof caving and roof leakage accidents. In case of roof caving and roof leakage accidents, it is necessary to clean up the floating coal and false coal in the roof caving and roof leakage areas, and take measures to tightly seal the roof caving areas.
5. After the mining of the working face, all kinds of equipment must be recovered to ensure that the roof of the goaf can fully collapse and be dense, and try to eliminate the air leakage in the goaf; Before the bolt supporting roadway enters the goaf, the supporting plate should be removed.
6. After the end of the mining face and mining area, a permanent airtight (firewall) must be built as soon as possible, no later than 45 days.
7. The goaf airtight (firewall) must ensure the quality, tight air leakage, cut during construction, cut depth meets the requirements. When a permanent seal (firewall) is built in the water gushing place, a return pipe should be set and a cement base should be laid.
8. The closed working face or mining area shall not be unsealed until it is confirmed by sampling and testing that there is no spontaneous combustion.
9. When unsealing the closed working face or mining area, safety technical measures to prevent coal spontaneous combustion must be formulated.
10 within three days after the closed working face or the mining area is unsealed, the ventilation work must be checked once per shift by the mine rescue team, and the water temperature, air temperature and air composition should be determined. Production can only be resumed after it is confirmed that there is no spontaneous combustion.
1 1. All underground electromechanical rooms and powder magazines should be equipped with fire fighting equipment such as dry powder fire extinguishers and sand boxes, and the minimum quantity is: 4 fire extinguishers and 0.4m3 sand.
12. The belt conveyor head shall be equipped with at least two fire extinguishers, and the fire-fighting pipes within the range of15m nearby shall be equipped with tees and valves, and the fire-fighting hoses shall be equipped with at least10m.
13. The underground fire-fighting material warehouse is located at the bottom of the well and equipped with fire-fighting trains. The variety and quantity of materials and tools should be recorded in detail, and the mine manager should organize relevant departments to check once every quarter, and solve problems in time when found.
14. Fire fighting equipment in various places is managed by mechanical and electrical departments, transportation teams and mining teams. Expired fire-fighting equipment must be replaced in time, and hardened sand should be loosened or replaced in time.
15. The management unit must supplement the equipment consumed by fire fighting treatment to the specified quantity within 24 hours.
2. Mine safety knowledge
1 safety inspection content: Henan coal mine safety regulations and basic standards for coal mine safety.
2 Coal mines must fill in and draw drawings reflecting the actual situation in time 1 Mine geology and hydrogeology Figure 2 Comparison between underground and underground Figure 3 Roadway layout Figure 4 Mining engineering plan Figure 5 Ventilation system Figure 6 Underground transportation system Figure 7 Safety monitoring equipment layout Figure 8 Pipeline systems such as drainage, dust prevention, fire prevention, grouting, compressed air, filling and gas extraction. 9 Underground Communication System Diagram 10 Underground Power Distribution System Diagram and Underground Electrical Appliances Layout Diagram 1 1 Underground Disaster Avoidance Roadmap 3 Requirements for entering the well: personnel entering the well must wear safety helmets, carry self-rescuer and miner's lamp with them, and tobacco, ignition materials, chemical fiber clothing, drinking before entering the well and mental patients are strictly prohibited.
Coal mining enterprises must establish a system of health examination and inspection in and out of wells. Four natural disasters: gas, coal dust, flood, fire and roof.
5 One ventilation and three prevention: One ventilation refers to ventilation, fire prevention, gas prevention and coal dust prevention. What is mine gas? What are the main ingredients? Mine gas is the general name of all kinds of harmful gases released from coal seams, rock strata and mined-out areas during coal mine production.
There are mainly biogas (SH4), carbon dioxide (CO2), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2) and hydrogen sulfide (H2S). Properties of carbon monoxide: Carbon monoxide is a colorless and odorless gas with a specific gravity of 0.97 lighter than that of air, which is generally flammable and explosive in the middle and upper part of roadway. According to the regulations, the concentration of carbon monoxide underground shall not exceed 0.0024%. Three elements of gas explosion: the gas content is 5%- 16%, with 650-.
Oxygen content is not less than 12%. The explosive power is the strongest when the methane concentration reaches 9.5%.
Three violations refer to: illegal operation, illegal command and violation of labor discipline. 1 1 Hazard of watt-hour explosion: 1 After the gas explosion, it not only caused a large number of casualties, but also produced high-temperature and high-pressure gas, destroying underground facilities.
After the gas explosion, the temperature at the explosion point drops, and the air is thin, which forms a reverse impact force and increases its explosiveness. After the gas explosion, a large amount of oxygen participated in the combustion, resulting in low oxygen content, and at the same time, due to the increase of carbon monoxide, a large number of casualties were caused.
4 After the gas explosion, the high temperature (1850 degrees) caused a fire. After the gas explosion, communication facilities and ventilation system were destroyed, which brought difficulties to mine rescue.
10 One shot and three inspections: before charging, before blasting and after blasting. 1 1 requirements of the anemometer station: it should be located in the straight lane, with its own length not less than 4m, and there are no obstacles such as detours in front and back 10m. The anemometer station shall have a record board marked with a number.
In the wood-supported roadway, a wind measuring station is set up, which is in close contact with the wind roof, so that all the air volume in the roadway can pass through. 12 three uses and two locks: three uses refer to special transformers, special switches and special lines.
2. Locking: refers to wind power locking and pneumatic locking. 13 "three pairs" of gas inspection refers to the record board of the gas inspection place, the inspection manual carried by the gas inspector and the gas account on the ground.
Main contents: inspection place and inspector's name, inspection date and frequency, specific time of each inspection and inspection results. 14 what is an independent ventilation system? The return air of mining area or mining face directly enters the return air lane, and no longer enters the ventilation system of other mining faces or other places where wind is used.
15 series ventilation: the ventilation mode in which the return air from the mining face or cavern enters other mining faces or chambers. The harm is that the air in the mining face or the series cavern cannot be guaranteed.
When the current mining face or cavern is in disaster, it will affect the series working face and expand the scope of the disaster area. According to the regulations, with the approval of the mine manager and chief engineer, series ventilation shall not exceed twice, and the gas concentration in series ventilation shall not exceed 0.5%. 16 circulating air: circulating air generally occurs in the local ventilation system, that is, part or all of the airflow enters the same intake air.
Hazards: The concentration of toxic and harmful gases and dust will increase when the wind in the heading face returns to the heading face repeatedly, which is not only the deterioration of the working environment, but more importantly, the increasing gas concentration in the airflow will easily lead to gas accidents. According to the Regulation, the local ventilator and its starting device must be installed in the air inlet roadway, and the distance from the air outlet is not less than10m.
17 upward ventilation and downward ventilation: for mines or inclined lanes, the ventilation mode of upward airflow is called upward ventilation; On the contrary, the ventilation mode of downward airflow is called downward ventilation. 18 the specific contents of "three noes, four noes, two neat, three complete and two lasting" for underground power supply are: three noes: inorganic chicken feet, sheep tail and unknown joints.
Fourthly, there are overcurrent and leakage protection devices, screws and spring pads, sealing rings and baffles, and grounding devices. Sanquan: complete protective devices, complete insulation appliances and complete drawings and materials.
Persistence: Adhere to the use of leak detection relays, adhere to the use of coal electric drills, fully protect lighting and signals, and adhere to the use of gas and wind power locking. 19 requirements for 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 frequently used miner's lamps 10%. Every lamp should be numbered, and people who often use miner's lamps must be illuminated by special personnel.
3. The miner's lamp should be intact. If there is battery leakage, insufficient brightness, wire loss, bad lamp lock, loose lamp holder ring, broken glass, etc. It is forbidden to issue miner's lamps. The minimum miner's lamp can be used continuously 1 1 hour. 4. The lighting room personnel must report the list of personnel who have not returned the lights to the mine operation department 2 hours after each shift change.
What are the signs before the mine is flooded? Before flooding, there may be signs such as sweating, redness, water screaming, air cooling, fog, etc., such as obvious pressure increase, floor bulging, roof drenching, mud inclusion in rocks, roof caving, etc. 2 1 principle of water exploration and discharge: state-owned: if in doubt, you must explore, explore first and then collect; Township; Explore before digging, explore before mining.
22 Timber yard requirements: The timber yard shall be not less than 80m away from the air shaft. 23. Ground fire pool regulations: The ground fire pool must maintain a water volume of not less than 200 cubic meters.
Fireworks or stoves are not allowed to be used for heating in the well and within 20 meters near the ventilation room. 25 handling misfire shall comply with the following provisions? The fire must be handled under the direct guidance of the team leader and should be handled on duty.
If it is not handled on duty, the blaster must hand over with the same blaster at the scene. Before the misfire treatment is completed, it is strictly forbidden to carry out work unrelated to misfire treatment on site.
What are the rules of the blaster?
3. Coal mine safety knowledge (online, etc. )
1 In case of emergency, hedge.
Because the belt conveyor is wide, large pieces of gangue may run out and hurt people. Because the mined-out area is easy to hurt people when it collapses, the so-called temporary support is to support the roof with unstable things such as hydraulic props or wooden boards, and its main function is to protect the safety of construction workers during temporary operation.
The safety work that the team leader should do probably includes checking the status of the personnel, such as the health status of the personnel, whether to drink alcohol, etc. In addition, check whether everyone's miner's lamp and lifesaver are correctly arranged and dispatched for underground operation, mainly the use of winch. Gas control measures mainly include turning holes for drainage, water injection, ventilation and other necessary measures.
Brother, your hands are so tired! .
4. Eight fire safety knowledge
Eight contents of fire safety knowledge
1. Consciously safeguard the public's fire safety, and call 1 19 to report to the police when the fire is found, and the fire brigade does not charge for fire fighting.

3, 2-3 meters from the root, the best distance. The effective distance of the fire extinguisher is only 4.5 meters.
The principle of "three rescues" to be followed in case of fire.
1, smoke prevention. Cover your nose and mouth with a wet towel for 3-8 layers (only 3-5 minutes). If there are no conditions, you can sprinkle urine on your clothes to prevent smoking.
2. Grasp the direction and escape. When a fire breaks out, it is best to use stairs, evacuation passages and open stairs where the smoke is not strong or the fire has not yet burned. But in the case of opaque or unfamiliar environment, climb from the ground to find the wall, follow the wall to find the door (clockwise or counterclockwise), and escape from the door.
3. Use tools to escape. For fires below the third floor, use ropes in time (or tear windows and sheets into long strips) and tie them firmly to objects that can bear weight, such as water pipes or heating pipes, and the other end will hang from the window to the ground or the lower balcony, and then slide down the rope to escape. Fire hydrants can be used to escape from fires on the 4th-6th floors.

Extended data
note:
1, dry powder fire extinguisher belongs to suffocation fire extinguishing, and is generally suitable for solid, liquid and electrical fires.
2. Carbon monoxide fire extinguisher, 12 1 1 fire extinguisher belongs to cooling fire extinguishing, and is generally suitable for fires of books, archives and precision instruments.
3, when using carbon dioxide fire extinguishers, be sure to pay attention to safety measures. Because when the carbon dioxide content in the air reaches 8.5%, it will raise people's blood pressure and make it difficult to breathe; When the content reaches 20%, people will breathe weakly, and in severe cases, they will suffocate.
