.Before you begin exploration, you should have the answers to the following questions:1.Is the evacuation complete? Are any miners missing? If so, how many and what are their possible locations?2.What is known about the cause of the disaster?3.Is your team the first one to explore? (In multi4evel mines, the team would also want to know if there are any other teams working on other levels.)4.Have the shaft and hoist been checked and, if so, what condition are they in?5.Have state and Federal officials been notified?6.Are guards stationed at all mine entrances?7.Is the ventilation system operating? Is it an intake or exhaust system? Are attendants posted at the surface ventilation controls? Have air samples been taken? If so, what are the results?8.Will there be a backup team standing by at the fresh air base, and reserve teams on the surface?9.What are the team's objectives and what is their time limit?10.What conditions are known to exist underground? (Ground conditions, water, gas, etc.)11.Is the mine's communication system operating? Is it being monitored?12.Is power to the affected area on or off13.Is there diesel or battery-powered equipment or a charging station in the affected area?14.What type of equipment is in the area? Where is it located?15.Where are compressed air and/or water lines located? Are they in operation? Are valves known to be open or closed?16.What type of firefighting equipment is located underground? Where is it?17.What tools and supplies are available underground? Where are they?18.Are there storage areas for oil or oxygen, acetylene tanks, or explosives in the area to be explored?VII.Going undergrounda.Captain's Responsibilities- Before your team proceeds to the fresh air base, it is the captain's responsibility to make sure the team, its equipment, and its apparatus are ready to go.In this capacity, the captain should:1.Check each team member to make sure he or she is physically fit to wear the apparatus and to perform rescue work.2.Make sure that each team member's apparatus has been properly prepared and tested.3.Make sure the team has all necessary tools and equipment (including the captain's own supplies: notebook, pencil, chalk, and so on).Once your team arrives at the fresh air base, it's the captain's responsibility to make the final preparations and arrangements before the team proceeds beyond the fresh air base.The captain should:1.Make sure the team members understand the briefing instructions and what their individual jobs will be.2.Make sure the gas-testing equipment, the communication equipment, signaling equipment, and stokes basket or stretcher have been checked by the designated people.3.Establish with the fresh air base coordinator what communications will be used.4.Synchronize watches with the fresh air base coordinator.5.(If not the first team to explore) Get up-to-date information from the last team (or from the coordinator) about how far the last team advanced and what they found.6.Make sure your team's mapman gets an updated map from the last team's mapman or from the fresh air base coordinator.b.Getting Under Oxygen- Once all of these preparations and last-minute checks have been made, you're ready to put on your apparatus and get under oxygen.Once the team is under oxygen, the captain checks each team member and breathing apparatus.The co-captain performs the same checks on the team captain.When the checks are completed, the captain notifies the fresh air base coordinator that the team is ready to proceed, and asks permission to set out.Before the team leaves the fresh air base to begin the exploration, the captain should be sure to take note of the time of departure.Some teams jot down the time on their map for later reference.Every exploration is different.Each one is an unknown situation, so each presents its own problems.Although it's difficult to tell exactly what you'll be doing during any exploration, there are some accepted procedures for carrying out basic exploration work.These procedures have developed over the years as mine rescue teams gained experience.They should be thought of as "guidelines" rather than "rules" because they are fairly flexible.Let's take a look now at some of the standard techniques and procedures you'll use during exploration.c.Team Check- One standard procedure you'll use during an exploration is the "team check." There are three reasons for the team check:1.To make sure each team member is fit and ready to continue,2.To make sure each team member's apparatus is functioning property, and3.To give the team a chance to rest.Usually, the captain conducts the team checks by simply halting the team briefly, asking each team member how he or she feels, and checking each apparatus.It's recommended that these team checks be conducted every 15 to 20 minutes.It is also recommended that you make your first stop for a team check as soon as possible after leaving the fresh air base.There is a good reason for stopping close to the fresh air base: If a team member is feeling unfit to travel or an apparatus is malfunctioning, the journey back to the fresh air base is relatively quick and easy at this point [ Pobierz całość w formacie PDF ]
