Research aim is to analyse the experience of operation and provide the technical-economic estimate of the
cyclic-fow technology (CFT) application and prospects at Bachatsky coal mine, which is a branch of UK
Kuzbassrazrezugol OAO.
Research relevance. The introduction of the cyclic-fow technology is a priority direction of upgrading
mining when developing deep ore pits and coal mines. It is therefore relevant to discover the basic reasons
why the mentioned technology is inefcient at Bachatsky coal mine and estimate the prospects of its
application with further development of mining.
Research methodology. When performing the set task, project documentation and actual operation indexes
of CFT at Bachatsky coal mine were analysed for the period of 2010–2017, process design solutions were
considered for the variants of reconstruction into the complex of overburden transportation to the dump
Iuzhny and the variant of a new CFT complex construction at the eastern pit edge, economic appraisal of
the variants was carried out, and the prospects for CFT application with further development of mining
were estimated. The methods of economic and mathematical modeling, technical economic analysis and
mining geometry analysis were used.
Results. It has been stated that the most efcient is the variant with the complete removal of the existing
CFT complex and switch to overburden transportation to the dump Iuzhny by motor vehicles. Process
design solutions on a new CFT complex construction at the eastern pit edge were proposed. The location
and the structure of the complex and the structure of the crushing and dumping station were substantiated.
Based on economic calculation, the conclusion has been made on high efciency of CFT when transporting
overburden to the pit dump Vostochny.
Research scope. The obtained results can be applied when designing and operating coal enterprises with
opencast mining technology; it will make it possible to avoid erroneous solutions made at the design and
CFT equipment selection at Bachatsky coal mine.

Key words: cyclic-fow technology; mine; motor vehicles; conveyor; crushing and dumping station;
transportation load; prime cost; efciency; reconstruction.
