How often shall entrances to old works be traveled and examined?

The requirement to travel and examine entrances to old works at least once every week is based on the need to ensure safety and maintain awareness of conditions that may change over time in these areas. Frequent inspections are crucial because abandoned parts of a mine can develop hazardous conditions such as collapsing structures, water accumulation, or the presence of toxic gases that may not be immediately obvious. Regular weekly examinations provide a systematic approach to checking for these potential dangers, helping prevent accidents and ensuring the ongoing safety of personnel who may be near or working in the vicinity of these areas. This frequency allows for timely detection of changes and necessary interventions, aligning with best practices in mine safety management. Other intervals suggested, such as every two weeks or once a month, may not be sufficient to address the dynamic risks associated with older mine workings.
