Background
World’s No.1 output
China is both the world's largest producer and consumer of mining resources, with the mining industry accounting for 17% of global production value.
Personal experience
One colleague of my father was killed when he was run over in the blind zone of a forklift truck while working underground.

From 2014 to 2024, a total of 56 mining traffic accidents occurred, resulting in 91 miners dead and more than 33 miners injured.

Others
Accidents are mainly caused by blind spot and misjudgment of vehicles motion state.

Research
Due to the typically large size of mining vehicles and the narrowness of mine shafts, significant blind spots are created, cause huge safety risks.
Large blind spots
High temperature underground
Contrary to what one might imagine, the underground environment is extremely hot, causing many miners to work shirtless. The deeper they go, the higher the temperature, reaching up to40°C.
Obvious Tyndall effect
There is abundant dust underground and the environment is relatively dark, leading to a noticeable Tyndall effect.
Low safety coefficient
The safety coefficient of underground mine is low, there is no active safety system, people and vehicles can not get effective communication and make timely avoidance.

There is a lot of oil and grime underground, which can easily obstruct vision, so the equipment needs to be easy to clean.
Under high-intensity work conditions, miners need PPE that is straightforward and easy to use, simplifying their tasks. Additionally, it should be lightweight to minimize extra weight burden.

Fatigue
Misjudgment
Working 8 hours per day, rest 1 day after 3 workday.
The eight hour continuous night shift makes it difficult for miners to concentrate and Irregular sleep patterns lead to fatigue. Security features must be enhanced due to long hours of work easily fatigue miners

Misjudged the turning area when the car turned due to the large size of the car.

The frosted texture of the plastic can provide a reduced sense of wear and tear and improve confidence in use.
3D printing was used to make this prototype.

USER TEST
The test was conducted by having three test subjects of different body types wear the production to see if they all had good levels of comfort.

Outcome
MODULAR DESIGN
Each component is modular design, can be disassembled and cleaned greasy dirty separately, and can be replaced after damage to reduce replacement costs.
There is a buckle to connect personal protective equipment and helmet.
Strips can be torn of to keep goggles clean when goggles getting greasy dirty.
The foldable stand allows it to be lifted when goggles are not in use, reducing line of sight resistance.
BLIND AREA
Warning range
As the distance gets closer and closer, the sound and vibration will have different degrees of progression, when the distance reaches the stopping zone, the intensity is the strongest.

logic
The additional warning light provides a reminder function on the basis of the continuous lighting of the white light.
A loudspeaker in the earmuffs alarms when a vehicle approaches.
A vibration motor in the earmuffs vibrates when a vehicle approaches, alerting miners by vibrating the skin.
Improve safety by reducing visual blind areas through positioning and prevent traffic accidents caused by blocked vision.
