Abstract
A procedure has been developed for estimation of elastic moduli and microhardness of elements composing heterogeneous materials, including coal and rocks. The procedure is based on the joint application of continuous nanoindentation and optical microscopy. The article gives an example of the procedure application in terms of two different coal samples.
