We have not taken such an action and, therefore, are required to use the SBA definition. MSHA traditionally has considered small mines to be those with fewer than 20 employees. The SBA defines a small mining entity as an establishment with 500 or fewer employees (13 CFR 121.201). Almost all underground coal mines fall into this category.
