Fireclay deposits in Kimovsk Coalfields

Conclusions

The Kimovsk clays occurring in alternation with coal seams as well as the underclays are suitable for the production of grade “B” and to a certain extent of grade “A” chamotte.

As a result of considerable losses on ignition only part of these clays is added to the bond in preparing mixtures for grade “B” refractories.

In order to increase the homogeneity of refractories, employ local Kimovsk clays and more rationally possibly launch grade “A” production on their basis, it is necessary to forego the use of Suvorovsk and Latnaya clays and plan necessary to forego the use of Suvorovsk and Latnaya clays and plan selective mining at the Kimovsk coal fields.

The planning of simultaneous but separate fireclay and coal mining at Kimovsk Coal fields is an urgent problem that calls for an expeditious solution.
