Underground Rescue: Equipped for Every Emergency

Every mine is different and yet they all have one thing in common: if an emergency occurs, the goal is to get everyone to safety quickly. Mining rescue plans depends on a variety of factors including whether the site involves an open-pit mine, above or underground rescue, metal/non-metal mines. The mining rescue equipment and solutions you use will be as unique as your own mine.

Emergency Escape

Safe escape plan in an emergency

Within the scope of the risk assessment, the specific risks associated with a particular method of mining and the type of resource mined must be analyzed. This assessment forms the basis for the escape and rescue concepts to be used in the mine.

Effective Escape Planning

Underground - Self-escape or rescue mission?

If a serious incident occurs underground, a decision must be made within minutes of whether self-escape is possible or whether a mines rescue team should be deployed. How is that decision made?

Self-escape in Coal Mines

Self-escape means: Victims of incidents are able to get themselves to safety and back to the surface without any additional help. This is almost always the case when emergency escape distances are short enough to be managed on foot. Keeping in mind that the escape route has to be open. So, when an incident occurs, there is no flooding, collapses or rockfalls blocking the way. Read on to find out more about examples of self-escape underground and the appropriate methods and equipment.

If coal catches fire: it's time to get out – fast!

Depending on the kind of coal being mined and the conditions at the face, a fire can take hold fast, intensify, and burn for a long time. Due to this, self-espace is the usual and best option.
In the following graphics, we show you what self-escape plans look like around the world’s coal mines – and how South Africa handles exceptions.

Sufficient breathable air

When escape routes are long, a switch to compressed air breathers may make sense, but limited air capacity is a drawback. Breathing air cylinders can be quickly and simply replenished at refilling stations like the Dräger ChargeAir.

Metal/non metal

Some extraction projects in the international mining industry extend to almost gigantic lengths and depths. Deep mining aptly describes mining at ever increasing depths – today, mining is carried out at depths that would have been unimaginable, not all that long ago. It also means that escape routes are longer and that there is no way to complete an escape entirely without any third-party assistance. Read on to find out more about escape planning, equipment and strategies for deep mines.

Escape in metal mines: don't panic – stay calm!

In ore and mineral mines, underground escape routes are often long and steep. Here, the key priority is to stay calm, find a safe refuge – for instance in a refuge chamber – and wait for rescue team organized at the surface. This is illustrated in exemplary form by escape plans for mines rescue, like those from South African gold mines.

Rescue Chambers FAQ

In case of an emergency in an underground mine, the escape way to the surface or a meeting point might be blocked or the conditions underground too difficult to initially escape. Refuge chambers provide mine workers access to clean air and temporary protection until they can be rescued. This list of FAQs offers a few facts to consider when incorporating refuge chambers in your emergency response plan.

Self-escape or rescue mission?

Above ground, emergency response plans generally anticipate self-escape and the provision of designated assembly points for mine personnel. Risk analysis provides information about potential risks or hazards involved. In downstream processing facilities, particularly with toxic hazards or the risk of explosions. Third-party rescue becomes necessary when personnel are unable to rescue themselves by escaping to a safe location.

Appropriate escape or rescue equipment depends on the results of risk assessment and the emergency response plan. The relevant criteria here are the degree of contamination with hazardous substances, the length of escape routes, possible oxygen deficiency, or fire.

8 points you should consider

Number 1 dark gray

Hazardous substances

Which hazardous substances (gases, vapors, particles) might occur? What are the limit values? Which maximum concentrations are to be expected during an incident? Could there be a lack of oxygen?

Number 2 dark gray

Fire and explosion risk

How high is the risk of a fire or explosion? Does the rescue device require ATEX approval? Will it need to offer protection against flammable gases? Does the material have to be flame-resistant?

Number 3 dark gray

Protection factors

From the determination of the potential hazardous substances, the applicable limit values and the hazardous substance concentrations during the worst case, the value of the protection factor is derived, which the rescue device must have in order to provide adequate protection during an evacuation.

Number 4 dark gray

Evacuation time

The emergency protection plan defines the time frame available for an evacuation during specific emergency scenarios. The rescue device must be able to operate during this time frame (minimum).

Number 5 dark gray

Rescue location

Is it possible to escape to a safe location? Might the users have to wait at a protected location for further evacuation?

Number 6 dark gray

Strain

Maintaining proportionality is also important: A user must carry his tools and other equipment. In some cases, he is already exposed to severe physical strain due to tight spaces, conditions such as heat, high humidity and poor visibility. The rescue device must adequately cover the calculated risk - but at the same time, its weight and impact on breathing should be kept as low as possible.

Number 7 dark gray

Ease of use

Intuitive and quick handling can save valuable seconds during an alarm and save lives. The more comfortable a rescue device is, the lower the risk of user errors.

Number 8 dark gray

Cost efficiency

In addition to the acquisition costs, there are other criteria for the cost efficiency of a rescue device: service life (durability during storage), re-usability, utilization options also during regular respiratory protection events, maintenance intensity and cleaning effort.

Emergency Response

Emergency response equipment firefighting team at mining entry

Emergency response and mines rescue

When an alarm goes off, everything runs at top speed: from the search for source of the alarm to the communication with the emergency control center. Safety management must quickly decide what options within the mine emergency plan are viable and, if necessary what escape or rescue measures for effected mine workers should be taken. High levels of knowledge and experience are needed, as well as the optimal provision of reliable safety and rescue equipment.

Deep mining rescue vehicle

Deep Mining

Mines change and evolve. They become longer and deeper, more complex. These changes need to taken into account, when engineering new processes but it is also a challenge for mines rescue teams. In case of a mine emergency, they gain an overview of the situation, evaluate potential risks, examine different scenarios and then decide – based on the specific mine emergency response plan – on the optimal rescue mission.

Deep deeper deepest mining infographic

Deep, deeper, deepest

The international trend of “deep mining” continues: Increasingly deeper seams are being mined, with the result that escape and rescue routes are becoming longer.

This has implications for the mine emergency response concept: Strategic planning of fresh air stations, refill stations for breathing air and refuge chambers are becoming more important. It is obvious that: Mines rescue teams have to travel longer distances to reach the incident site with only a limited amount of time available.

Challenges of Mines Rescue in Expanding Mine Operations

Success begins with getting rescue teams to the action quickly and safely. As mining operations develop, the underground workings extend farther from the shaft or portal, and become more complex as they continue to expand. Travel distances and time increase.
