Fatal underground coal mine injuries are a worldwide problem. Zonguldak holds 95% of all Turkey's coal reserves.
To investigate fatalities in the underground coal-mining industry in the Zonguldak province.
Retrospective study of fatal underground coal-mining accidents from 1994 to 2003 through evaluation of industry records.
There were 164 deaths available for analysis. The median age was 36 years (range: 14-56 years). Eighty-one fatalities (49%) were due to subsidence, 33 (20%) were due to underground railway accidents and 18 (11%) were due to gas poisoning. Asphyxia was the most common cause of death (99, 60%). The majority of fatalities (144, 87%) occurred instantaneously at the scene of the incident. The remainder (20, 13%) occurred on the way to the hospital or in the emergency room or the intensive care unit.
The underground coal-mining industry in Turkey requires strategies to improve safety and reduce the number of fatalities occurring. These strategies should focus on improved underground safety through engineering measures.

- "The mining industry has the highest incidence of occupational deaths among all industries. Common causes of occupational deaths include rock falls, fires, explosions, methane intoxication, and electrocution . "

In this study, our aim was to evaluate the fatal occupational accidents that occurred in Zonguldak coal mines between the years 2005–2008.
We retrospectively evaluated 42 fatal coal mine occupational accidents in Zonguldak (Turkey) between the years 2005–2008. The forensic records of autopsies referred to the chief prosecutors’ office during 2005–2008 were reviewed retrospectively. There were 42 cases. The cases were evaluated with respect to age, mechanism of injury, body region of wound, cause of death, and legality of the mine.
Ages of the deceased ranged between 17 and 52 (median: 32.9 yrs). Deaths were mostly in the 21–30 (35.8%), and 31–40 (30.9%) age groups. Only 1 case was younger than 18 years of age. Review of occupational fatalities has revealed that fatal accidents occurred mostly (76.2%) in the private, and fewer (23.8%) in the public mining enterprises. Crime scene investigation findings have demonstrated that of all occupational deaths (total n=42), 27 (64.3%) were due to subsidence, followed by methane gas poisoning (n=6, 14.2%), tram crash (n=3, 7.1%), log falls (n=2, 4.8%), electrocution (n=2, 4.8%), and methane explosion (n=2, 4.8%).
Despite laws and regulations concerning mining and because of problems in their implementation, Turkey leads the world in work-related accidents, occupational injuries, and deaths. Evaluation of autopsy findings of deaths in fatal occupational accidents occurring in coal mines is quite important in planning to decrease rates of occupational fatalities.

- "Nonetheless , there are still significant mining risks such as flooding , fall of ground, underground fires, handling and use of cyanide, storage of and exposure to radiation materials, and other airborne pollution that need to be addressed. These have been responsible for a continuing series of environmental and health disasters, which cause great human tragedies and loss of life and undermine social or economic stability and sustainability    . Mining remains one of the most hazardous environmental occupations worldwide with underground coal and gold mines characterized by high accident rates even in relatively efficient mining operations [6– 8].

ABSTRACT: The performance of a proposed compact radial basis function was compared with the sigmoid basis function and the gaussian-radial basis function neural networks in 3D wireless sensor routing topology control, in underground mine rescue operation. Optimised errors among other parameters were examined in addition to scalability and time efficiency. To make the routing path efficient in emergency situations, the sensor sequence and deployment as well as transmission range were carefully considered. In times of danger and unsafe situations, data-mule robot with Through The Earth (TTE) radio would be used to carry water, food, equipments, and so forth to miners underground and return with information. Using Matlab, the optimised vectors with high survival rate and fault tolerant, based on rock type, were generated as inputs for the neural networks. Particle swarm optimisation with adaptive mutation was used to train the neurons. Computer simulation results showed that the neural network learning algorithm minimized the error between the neural network output and the desired output such that final error values were either the same as the error goal or less than the error goal. Thus, the proposed algorithm shows high reliability and superior performance.

ABSTRACT: The metal mining industry employs approximately 15% of formally employed workers in Zambia, but there is little information about the magnitude of occupational injuries among the miners.
To determine the frequency rates of occupational injuries and fatalities among copper miners in Zambia.
A retrospective study of occupational injuries and fatalities at one of the largest copper mining companies in Zambia was undertaken for the period January 2005 to May 2007. Information on injuries and fatalities was obtained from the electronic accident survey database of the company. Analysis was restricted to fatalities and those injuries that had prompted medical attention and at least 1 day of absence from work. Annual injury and fatality frequency rates (injuries per 1000 employee years and fatalities per 100 000 employee years, respectively) were calculated.
In the selected period, 165 injuries and 20 fatalities were recorded. The underground department had the highest frequency rates of fatalities (111/100 000 employee years) and injuries (5.5/1000 employee years). The most common cause of fatal injuries was fall of rock in the underground mines. The most frequent mechanism of injury was handling of tools and materials, and the most commonly injured body parts were the hands and fingers.
The fatality rate is high compared to reported values from the metalliferous mining industry in developed countries, strongly suggesting that measures should be taken to reduce risks, particularly at underground sites.
