The proper size of coal pillars and mining width for partial mining are studied with theory of continuum mechanics. The expressions for calculating the vertical stress induced by coal extraction in coal pillars and width of plastic zone and formulae for the width of pillar and mining width are derived from a mechanical model based on the features of partial mining. These expressions are of practical value to calculations of other coal pillars in coal mining.
