NIOSH Mine Emergency Escape Simulation Technology Available for Developers
Posted on by
Background
All underground coal miners in the United States receive escape training on a quarterly basis. This training prepares them for exiting the mine in the event of an emergency and it must include walking either the primary or the secondary escape route from their work area to the outside (30 CFR, 2015). As a way to both study the mine emergency escape system and to supplement the existing training, NIOSH researchers developed the Mine Emergency Escape Training (or MEET) software. MEET uses a virtual immersive environment to create an underground coal mine escape experience focusing on knowledge of escape procedures while utilizing judgment and decision making skills. While NIOSH uses MEET as a research tool, others can use it in new miner, annual refresher, or emergency response training. MEET is appropriate for underground coal miners at any skill or experience level. NIOSH is offering the MEET software to developers interested in tailoring the training as well as to mine safety and health trainers, safety managers and others who can use it “out-of-the-box” for their training needs.
The software, already used to train over 1,000 miners, encourages participants to use critical thinking while escaping a virtual mine emergency. When used in a training scenario, the included instructor’s guide contains questions moderators can ask during the after-action debriefing to reinforce learning and stimulate discussion among participants about emergency evacuations. The software includes three distinct components:
- A pre-evacuation tutorial where users practice operating keyboard and mouse controls, interface with the simulation, and learn about tools available to aid their escape (Figure 1);
- The underground simulation where users start at predetermined locations in a virtual underground coal mine, and must evacuate to safety (Figure 2);
- A post-evacuation debriefing tool where the moderator reviews routes participants followed, actions they took, and decisions made.
Developed using the Unreal 2® game engine, MEET can operate in single player mode for display on a projector screen to a group of participants in a classroom, or multiplayer mode with up to four computers connected via a router for group sessions. Multiplayer mode allows more than one participant to join the virtual mine escape with each computer representing a different miner who must evacuate. Once underground, players can decide whether to work together to solve problems and make decisions during their evacuations or to evacuate on their own.
In the underground simulation participants are told of the discovery of smoke from an unknown source and that they must evacuate the mine. They must decide the course of action to successfully escape to safety. Based on information presented throughout the simulation, they decide their escape routes, when to change their route, when to don a self-contained self-rescuer, what to do when they encounter a roof fall in an escapeway, and whether they should retreat to the refuge chamber.
In the simulation participants have a variety of tools they can use to help in their escape including escapeway lifelines, self-contained self-rescuer caches, multigas meters, survey markers, and tether lines.
Following the underground simulation, the moderator may conduct a debriefing session. For each run of the simulation, the software records all actions taken by participants and can display a map in the debriefing tool (Figure 3) to review the escape routes and actions escapees took. The post-evacuation debriefing serves as the basis for discussing escapees decision making and getting participants to talk about their decisions. They also have the opportunity to share personal stories and learn from each other.
NIOSH researchers conducted field-testing of MEET as a training tool with a mining company during their annual fire prevention training. The study included 68 trainees. The average age of the trainees was 39 years and they averaged over 10 years of mining experience.
In a post-training feedback session, trainees reported that the simulation was relevant to their needs and was realistic. Trainees also felt that the MEET simulation has robust training value in improving their preparedness.
NIOSH is making the MEET software available, as is, for download by mine safety and health trainers, safety managers and others. Click here to access MEET . You will find links to the MEET software, a PDF of the instructor’s guide and mine map, and a tip sheet for users. Our hope is that the mining industry will find the training aspects of the MEET software useful in improving their workforce’s ability to handle mine emergency evacuations.

this sounds like a very useful tool for training but does not replace actual escape practice under MSHA regs. It would be interesting to see how miners with little computer familiarity or English as a second language respond to the simulation.
Ya, it looks like a game. But it help a lot.
People, who play a lot on the kind of games, in the emergency situations dont fall on panic. His brain already ready to action. Ready to save people lives.
I remember one history, we were in the Central Asia mountings. It was second day of trip and one of us broke his leg. Imagine, at least 10 hours till the hospital. 10 hours of walking! no cars, nothing. Thanks god, one of us was addicted to his Roku TV and he saw how to help people in that situation. Thanks God and this guy! Literally TV show helped to save live! The same thing for games. Smart games.
is there a way to change the map so as to use the program for a different type mine
While there is an editing program for creating new mine maps, the process for creating these is time consuming and requires significant expertise with this software.
I have some familiarity with creating my own maps for games (mine craft, mostly). How difficult would it be to incorporate my organizations underground facilities?
MEET includes an editing program (UnrealEd.exe) that uses a CAD-like interface to allow developers to manipulate the placement of objects and setup triggers and simulation parameters. The process can be considerably more complex than editing Mine Craft. I’d be happy to discuss this in more detail if you contact me directly.
One more step forward for the advancement. keep doing the good work. 🙂
New to the zip file: We have added a guide for trainers on how to teach effectively with the software, ‘Teaching Problem Solving and Decision Making with the MEET 1.0 Software and Other Computer-Based Simulations.’ This ten-page guide combines what NIOSH researchers have learned from observing how trainers and trainees have used MEET 1.0 in the field with what they know from research on learning. The advice is general enough to apply to other computer-based virtual reality simulations focused on problem solving and decision making. Topics covered: giving sufficient practice time with the computer before the exercise; the importance of allowing trainees the room to make mistakes and learn from them during the exercise; and the advantages of a trainee-focused debrief.
Great. It would be interesting to see how miners with little computer familiarity or English as a second language respond to the simulation.
Nice. It is fascinating that how miner can do there training so easily.
Great! it’s a one more step forward for the advancement. Keep doing the good work, Tim!
It is amazing how far technology has come to enable coal miners to be trained for exiting a mine in the event of an emergency. It is great that emergency escape systems can be experimented with to tailor the training to different skill or experience levels. My good friend grew up in a coal mining town, she has shared with me the fear she has experienced in wondering if her father would make it home in the event of an accident. These sort of programs have provided her with peace of mind.
This exploratory work is a critical first step in an Instructional Systems Development approach to improving system preparedness and self-escape training of underground coal mine personnel. The outcomes of these activities, along with the continued analysis of quantitative and qualitative data associated with existing mine emergency response training, will be combined to produce a solid framework from which enhanced self-escape training and assessment materials can be developed and tested in a controlled research setting.
Great. Keep it Up.
It’s really helpful for miners.
I am very pleased to discover this blog. As Software technology will play a key role in future.
Hi,
very good post
