4. Action plan

(I) the step-by-step process of the announcer before entering the mine

after receiving the disturbance alarm from the mine, the report to the next level according to the law, At the instigation of carrying gas explosion equipment, two teams were dispatched immediately. The announcer should immediately use all available means to understand the disaster in detail, determine the growth trend of the disaster, the plans and methods adopted by the mine, make decisions in a timely manner, and issue orders to take care of the disaster

1) the announcer must appreciate the contents to be grasped

① the fire source that can be presented. ② Explosion address and its scope. ③ The spread of the escape workers and their casualty environment. ④ Ventilation environment, such as large or small wind volume, the target of the wind vane, the damage environment of the damper and ventilation buildings, etc. ⑤ Gas environment in disaster areas, such as gas concentration, smoke, CO concentration and its flow direction, temperature, etc. ⑥ Is there a fire alarm. ⑦ The main task of the ventilator is to check whether the local fan operates normally. ⑧ Methods adopted. ⑨ If the roof falls after the explosion, the air duct is blocked. ⑩ Whether there will be a continuous explosion

2) 1. Before entering, do a good job of pre station inspection, implement the learning plan and Enron technical measures, block the power supply in the disaster area and the power supply that can reach the regional power supply and the return air line in the disaster area, and assign special personnel to take care of it. 2. Evacuate employees from disaster areas or areas that can be reached. 3. The following precautions shall be taken for the use of the friction and wear testing machine away from the accident: in the Enron area near the address, a base under the vertical shaft shall be set. ④ Participate in the mine disaster relief Instruction Department, assist in the formulation of emergency relief action plan and Enron measures. ⑤ After reaching the mine, the rescue team shall be arranged according to the disaster relief plan to rescue the escaping staff, spy on the disaster, destroy the fire alarm, restore the ventilation system, and prevent another explosion

(II) action plan

plan 1

1. Send a small team to wear oxygen respirators and carry equipment into the disaster area to watch, and another team will stand by at the underground base. The team that first entered the disaster area shall promptly give rescue and transport out of the disaster area if it finds any surviving escape staff. In case of finding the dead employees who have indeed died, they should indicate the location of the victims, number and tag them, and then continue to make progress. After all the surveillance tasks in the disaster area are completed, the dead employees can be transported out of the disaster area or handed over to the follow-up team

2. Peep into the crushing environment of ventilation measures in the roadway, gas concentration, temperature, various harmful gas concentrations, and the scope of the disaster, report and teach at any time, make a good mark, and withdraw immediately in case of any abnormality

3. According to the gas environment, the fire alarm caused by explosion shall be destroyed immediately if it has the premise of direct fire extinguishing. If the fire is large and difficult to destroy at the moment, measures should be taken to prevent the fire from spreading to the site of the escape staff. After all the escape staff are rescued, the fire-fighting task should be stopped

(premise of direct fire extinguishing: ① clear fire source ② abundant water, manpower and material resources ③ unobstructed air return channel ④ gas concentration does not exceed 2%)

4. When the tunnel is blocked due to roof fall caused by explosion, other lines should be selected to enter the disaster area. If there is no other way to enter the disaster area, the team should immediately cut off the blockage. If the roadway is seriously blocked, air lock control should be adopted to restore ventilation outside the blocked area. It is not allowed to enter the tunnel when the visibility is low, there are blockages caused by explosion, it is impossible to make progress or the environment is not clear

5. Formulate a care plan according to the results of the surveillance

scheme II

1. When dealing with the gas explosion in the heading roadway, there must be a specially assigned person to carefully monitor (depending on) the gas environment, make every effort to rescue the staff in distress, destroy or eradicate the fire source, prevent re explosion, clean up the blockage, deal with the roof fall area, and timely restore the ventilation in the disaster area (start some fans) when it is certain that there is no fire source in the disaster area; If it is impossible to confirm whether there is a fire source in the disaster area, it should be carefully considered whether to start some fans to prevent another explosion

2. If the fire source is found, if it is easy to put out the fire directly, the fire-extinguishing equipment and equipment can be manipulated to destroy it in time, but it is necessary to pay attention to the gas environment and prevent people from being injured by water gas explosion. After extinguishing the fire, it is also necessary to check whether there is smoldering fire source. If the fire is serious. Or there are many fire sources, the tunnel cannot destroy the fire source in a short time, or there is a risk of secondary explosion when extinguishing the fire, the rescue team should be assigned to concentrate on rescuing the staff quickly, and then the handling method (such as closing the explosion tunnel) should be adopted according to the handling method of fire accident in the single head tunnel. Prevent the fire from spreading and then destroying. If, after the explosion, the gas in the roadway close to the explosion source is ignited, it shall be handled with caution (the roadway shall be closed in time) to prevent the gas explosion in the blind roadway

3. When the environment in the unknown roadway is unknown, select the far Enron interval closed roadway

5. Important matters and Enron technical measures

(I) surveillance in disaster areas

1 Basic equipment for disaster relief

no less than 6 employees shall enter the disaster area to watch or do homework. Before entering the disaster area, they must check whether the oxygen respirator is intact, and wear and use it as required. The team must carry one spare full mask oxygen respirator, two spare oxygen cylinders with a pressure not lower than 18Mpa, oxygen respirators and spare parts bags with accessories

2. Attention required for disaster relief

scheme I Enron technical measures

2.1 the commander of the mine rescue team shall personally organize and participate in the spy task. When placing the spy task, he must declare to all staff the various environments he appreciates. The spy task shall be clear, the travel route shall be clear, and the targets of the team shall be marked on the drawings

2.2 in case of areas with high temperature, roof fall, explosion and flooding risks, the commander has the right to decide the team to enter only under the environment of saving people and with the consent of the relief Instruction Department, and must adopt effective measures to ensure the safety of the team in the disaster area. The first-aid instructors who give instructions in the air should take turns to be on duty and go down to the well to learn about the environment. They should really keep in touch with the underground task team, the well base, the underground base and the logistics department, so that they can reasonably place the same instructions in the emergency handling tasks

2. 3 when traveling underground, the rescue team members shall detect various gas environments underground and evaluate the site conditions. Look for clues to the survivors. During the progress, all the discovered environment shall be recorded on the map and the underground base shall be stated

2. 4. When watching, Enron, who obeys the rescue team, is the first. It is strictly prohibited to take risks to improve or study in any environment

2. 5 the commander shall determine the rest time, address and time to go to the underground base of the rescue team according to the environment and tasks

2.6 cut off the power supply before entering the disaster area. If gas causes alertness, it should be considered that cutting off the power supply can cause gas accumulation in the task face and explode again

2.7 when entering the disaster area for tasks, it is not allowed to change the ventilation system at will, so as to prevent accidental changes. If the ventilation system is changed, it should be stabilized before entering the disaster area

2.8 after entering the disaster area, it is necessary to check the concentration of gas and other gases at any time, grasp the concentration of various gases, change the environment, and adopt measures to prevent continuous gas explosion. When there is an explosion risk, it is strictly forbidden to enter the disaster area. Only after the measures are adopted to confirm that there is no explosion risk, can it enter the disaster area for tasks

2.9 in case of open fire, the wind speed shall be strictly controlled to prevent coal dust from flying. The staff shall walk slowly to prevent coal dust from flying and causing explosion

2.10 when passing through the roof fall blocking area in the area where the support is crushed, the power and support shall be erected to ensure the safety of the team members when they return to and from these addresses. When passing through the poorly supported address, the team members shall keep a certain interval and pass through the process in sequence

Enron technical measures of scheme II

2.1 when entering the disaster area, we should take advantage of the morality of the disaster area, contact the underground base and the instruction department at any time, and set up a standby team, which can only be set up in the environment of suing, robbing and rescuing people

2.12 be careful when entering the disaster area to prevent sparks from collision and explosion

2. 13 progress and retreat

1) progress and comprehensive Watching: when the disaster area progresses, try not to enter the crushed roadway but stay at the air inlet. Stop "comprehensive spying" when making progress, make sure that every lane must be checked, and sign and leave your name

2) sequence of progress: when the rescue team makes progress in the underground, the team leader is the first and the deputy team leader is the last. On the contrary, when the rescue team goes, the team formation makes oblique progress with the roadway. The first aid team leader should be more advanced than other team members. The elder should go into the area not watched and check the roof and lane Gang environment. No other team members are allowed to enter the unprotected area where the team leader has not entered. The vice captain shall stay behind and observe the environment of all members of the team during the March. If someone has made achievements, the vice captain shall immediately order the rescue team to stop watching

3) speed of progress: during the progress of the rescue team, the team leader should adjust the method of the rescue team according to the actual environment. For example, when the field of vision is unclear, there is an obstacle or an inclined section, the rescue team has heavy equipment or the wounded, the two conventional materials should be corroded and rusted due to the presence of salt water

4) make progress in the smoke: according to the regulations of mine rescue regulations, when the smoke full visibility of the roadway is less than 1m, the rescue team is strictly prohibited to enter the peeping or homework. Measures should be taken to improve the visibility before entering

5) before passing the ventilation measures, the rescue team should first see whether there is smoke by touching the heat and indecency of it. Before building a power wind wall, it must be ensured that air alienation will not be formed and the original ventilation conditions will not be changed

6) follow the regulations when making the wind wall with the risk of gas explosion, and quickly evacuate to the Enron address after completing the sealing task. In the closed fire area, you must leave behind within 24h after entering the inspection or reinforcement

7) go: go within the specified time. In case of any team member's equipment and instruments showing defects, gas that can explode, fire that cannot be destroyed, or water inrush, or encountering roof tunnels that cannot be bypassed but are very risky, the team leader can order to go immediately

8) the relief staff must strictly implement the coal mine safety regulations and mine rescue regulations, as well as the relief plans and measures, Make sure you are safe

9) follow the instructions and orders of the relief Instruction Department in case of mine accident. When other relief forces participate in disaster relief, they should coordinate and cooperate with each other

3. Relief statement

the statement must contain all the primary environment, information and various signs encountered in the process of spying

1) environment of the team and each member
