Mine-shaft conveyance monitoring

Mining Engineering, 2000, Vol. 52, No. 10, pp. 28-31

ABSTRACT:
The shaft is the lifeline to underground mines. Miners depend on it for safe transport to and from the workplace and the efficient flow of materials. Hoisting accidents resulting in injury are uncommon, but all hoist accidents have the potential to be catastrophic. For example, in 1973 at the Markham Colliery in Derbyshire, UK, a conveyance overwound and fell to the pit bottom, resulting in 17 deaths. According to US Mine Safety and Health Administration (MSHA) data, many shaft-related accidents in the United States are associated with conditions related to the hoisting and loading-unloading cycle. One such condition, known as slack rope, is particularly dangerous, especially if it occurs without the operator’s awareness. Causes of slack rope in metal and nonmetal mines are often ground-control or guide-alignment-related, which can cause the cage or skip to become obstructed. Other hazards are related to falls of miners and materials, ground instability and malfunction of safety devices, such as conveyance doors, etc. Figure 1 shows the number of shaftrelated accidents by type in all underground mines from 1992 to 1996. These shaft-related accidents are based on a keyword search of MSHA narratives.
