Issue:

Peak summer sees increased incidents of mine workers affected by

high heat.

Opencast mines are most vulnerable.

Underground mines also affected due to poor ventilation.

Heat stroke is the major cause in most incidents.

Mine management must educate field officers and workers on heat-related illnesses and first-aid measures.

Physiological Effects of High Temperature:

cognitive/muscle tasks.
