Heavy work as a coal miner does not include harmful impact for fibromyalgia under work injury insurance law.

The court dismissed the claim that heavy work as a coal miner caused fibromyalgia under the Work Injury Insurance Act. The applicant argued that extensive medical examinations proved the disease resulted from occupational strain, while the opposing party contended the condition lacked a direct causal link to the specific duties. The court ruled that fibromyalgia does not inherently constitute a harmful impact arising from such work without further specific evidence of direct causation.
