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
Moroccan boy, Rayan, 5, trapped in 105-feet-deep well, found dead after four-day rescue effort https://eu.usatoday.com/story/news/world/2022/02/05/moroccan-boy-rescue-fourth-day-effort-free-5-year-old-well/6674664001/
- 105 feet deep well
- The solution was to dig a parallel hole to the well
- They sent down water as well as cameras to monitor the condition of the boy
- It seemed challenging to determine the condition of the boy therefore they kept digging.

- 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
'Boy falls into hole made for building in Vadodara https://timesofindia.indiatimes.com/city/vadodara/boy-falls-into-hole-made-for-bldg-rescued/articleshow/96657142.cms/
- 20ft (6m) deep hole
- Rescuers had to dig a parallel hole in order to save the boy.
- Rescue operation was less complicated compared to other situations as the hole was less deep.

- When digging holes, rescue workers have to be very careful to avoid letting the shaft collapse or letting debris fall in

- 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

- On average, 70% of rescue operations are unsuccessful
- Borewells are wells that can be 100-1500 feet deep and fit pipes of 6-12 inches in diameter in order to extract water to irrigate land
- Key factors that affect the rescue mission's chance of success include:
- Incident type
- Location
- Depth and diameter of borehole
- Availability of equipment for digging, oxygen, doctors, ambulances and lights
- Type of soil
- Problems with digging a parallel hole and diging a horizontal hole to the hole where the child is:
- Needs large amounts of resources (rescue workers, machines)
- Too time-consuming
- Hard rocks can get in the way of the digging and cause delays
Similarities between researched cases
- Location :
- Majority of cases occur in southern Asia (India, Thailand, ....)
- Type of hole:
- Borehole used for construction or to reach a well.
- Method of rescue:
- Supplying oxygen through a long pipe, digging a parallel hole.
- Supplying food/Water is not possible in most cases. Either the hold is too small or the victim is wounded/unconscious.
- Victim:
- A child between 2-12 years old.
Existing procedure on Bore well Incident Response
https://ndrf.gov.in/sites/default/files/SOP%20BOREWELL.pdf
- File created by the National Disaster Response Force, Government of India [2018-2019]
- The purpose of this 28 page document is to establish the procedure for the response of the rescue team for bore well incident. The Standard Operation Procedure (SOP) prescribes guidelines and assigns responsibility for adopting various executive actions to ensure prompt response during incident.
- The main objectives of SOP are:
- Guidelines for troops for rescue operation during the bore well incident.
- Achievement of best result through well planned rescue operations.
- Reducing reaction time of the teams in responding to such incidents.
- Coordinating and collaborative instructions during bore well incident.

Analsysis of incidents
- There were a total of 46 incidents described in the section above that happened from 2013 to 2023.
- how many incidents happend which each type of hole, for example narrow borehols or narrow wells?
Narrow wells: 21 incidents
Narrow boreholes: 16 incidents
Drainage pipe: 1 incident
- What was the avarage time spend in the hole?
The average time spent in the hole was approximately 33 hours
- What is the age distribution?
The age distribution of children who fell into narrow wells and boreholes between 2013 and 2023 is as
follows:
2-year-olds: 8 incidents
3-year-olds: 10 incidents
4-year-olds: 12 incidents
5-year-olds: 9 incidents
6-year-olds: 8 incidents
10-year-old: 1 incident
It can be seen that the majority of incidents involve children between the ages of 2 and 4 years old.
- borehole vs well:
A borehole is a narrow and deep hole drilled into the ground for the purpose of finding water, oil, gas, orminerals. It is typically used for extraction and exploration purposes.
A well is a hole dug into the ground to access water. It can be either shallow or deep and can be used for household or agricultural purposes. Unlike boreholes, wells can be used for both extraction and storage of water.
- What are the average dimensions of wells and borehols?
Casing on drilled domestic wells generally have a diameter of 4–8 in (most commonly 6 inches) in newer wells this is around 15,24 cm.
Casing on dug wells generally have a diameter of 60–120 cm (24–48 in)

Assuming that the weist is the biggest part in childs body this corresponds to the following avarage circumference per age. Assuming that on avarage the different between boys and girls is neglectable at
this age. This can be seen from the data. the average weist circumference of children from the age 2 to 6 is 48 cm to 57.1 cm. This correspons to a rough diamater between 15.28 cm and 18.14 cm.
