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: gas content 5%- 16%, with 650-.
Oxygen content is not less than 12%. The explosive force 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, the 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 on a straight road, 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 chamber in series cannot be guaranteed.
When a disaster occurs in the front mining face or cavern, it will affect the series working faces 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.
Hazard: The wind in the heading face returns to the heading face repeatedly, and the concentration of toxic and harmful gas and dust will increase, which is not only the deterioration of the working environment, but more importantly, the gas concentration in the airflow is getting higher and higher, which is easy to lead to gas accidents. The "Regulations" stipulates that 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.
Fourth, 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 frequent users 10%. Every lamp should be numbered, and those who often use miner's lamps must be lit by a special person.
3. The miner's lamp should be intact. If there is battery leakage, insufficient brightness, lightning falling off, bad lamp lock, loose lamp holder ring, broken glass, etc. It is forbidden to distribute miner's lamps. The minimum miner's lamp can be used continuously 1 1 hour. 4. Lighting room personnel must report the list of personnel who have not returned the lamp to the mine operation department 2 hours after each shift change.
What are the omens before the mine is flooded? Before flooding, there may be signs such as sweating, redness, water whistling, air cooling, fog, etc., such as obvious pressure increase, floor bulging, roof drenching, mud in the rock, roof caving, etc. 2 1 principle of water exploration and discharge: state-owned: if you have doubts, you must explore first, and then collect it; Township; Explore before digging, explore before mining.
22 Timber yard requirements: The timber yard shall be not less than 80m away from the wind shaft. 23 ground fire pool regulations: the ground fire pool must keep no less than 200 cubic meters of water.
Fireworks and 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? Dealing with misfire must be carried out under the direct guidance of the team leader and should be handled in shifts.
If it is not handled on duty, it must be handed over to the blaster at the scene with the same blaster. 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?
2. Coal miners' safety knowledge
