Research Section on Topic
Past Accidents
Thai baby who fell down well rescued https://www.bbc.com/news/world-asia-64553751
- 13m deep shaft and 30cm wide gap
- An adjacent tunnel had to be dug up in order to save the boy
- Oxygen was supplied to the tunnel
Boy rescued after 100 hours trapped underground in a well https://www.youtube.com/watch?v=Cwqsa9VkTQg
- 18m deep well
- An adjacent tunnel had to be dug up in order to save the boy
- Oxygen was supplied to the tunnel
Madhya Pradesh: Indian boy trapped in a well https://www.bbc.com/news/world-asia-india-63928144
- 17m deep well
- Trapped for 3 days. Again the solution was to dig a parallel hole
- The rocky layer seemed to pose complications on digging the parallel tunnel
Spain toddler stuck in deep borehole https://www.bbc.com/news/world-europe-46862385
- In this case the hole is 100m deep and just 25cm wide.
- This posed the problem that no one could actually fit through the hole, only a camera to locate the boy
- Again the best solution they used was to dig a parallel hole, which takes very long
Killer borewells: Recent cases of children falling into deadly holes https://timesofindia.indiatimes.com/city/mumbai/killer-borewells-recent-cases-of-children-falling-into-deadly-holes/articleshow/92232243.cms
- Cases of children falling into borewell holes dating back to 2006 up to 2022
- Rescue operations could take 9 up to 109 hours, and even then they were not always successful
- Children were aged 1.5 up to 9 years old
- Hole depths ranged from 55 to 440 ft (16.764 to 134.112 m)
- Rescue methods included digging a pit parallel to where the child was trapped using large excavators (up to 40 in one instance).
- Saving these children could often require a team consisting of the National Disaster Response Force (NDRF) team army, fire brigade, police and health officials.
- Geological obstacles included huge rocks or slab which would have to be broken up in order to dig a pit down to where the child was
- Oxygen would be pumped to the holes during rescue missions, but no food could be sent down
Boy, 10, declared dead after falling into 115-feet deep construction site hole in Vietnam https://www.cbsnews.com/news/boy-who-fell-into-115-feet-deep-construction-site-hole-in-vietnam-declared-dead/
- After 100 soldiers spent almost 100 hours a 10 year old boy could not be saved after being trapped for 5 days
- The hole was 10 inches (25.4 cm) wide and 115 ft (35.052 m) deep
- Rescuers attempted to use a 62-foot metal pipe to rescue the boy while oxygen was being pumped into the hole
Problems With Current Rescue Methods

Infant Girl Rescued from DANGEROUS Well Shaft in Thailand https://www.youtube.com/watch?v=EwNHVP34C8U&ab_channel=OnDemandNews
- When digging holes, rescue workers have to be very careful to avoid letting the shaft collapse or letting debris fall in
Rescue 911: Small Boy vs. Deep Hole https://www.youtube.com/watch?v=THnTA6Of0qM&ab_channel=brokkenp
- The more people get inovlved and look into the hole where the child is, the more dust gets kicked in accidentally and covers the child
- Water can rise at the bottom and make it harder to dig
- It can be very hard to accurately dig the horizontal hole to the child
- If the child's location is measured incorrectly from the ground level, the hole could miss them
