In February 2009 a full bat census in GMN- and IVK-mines (Khmelnytsky Oblast) was done. In total, 4801 individuals of 10 species were counted: 2438 of 7 sp. in GMN-mines and 2364 of 9 sp. in IVK-mines. The carried work is the first experience of a full bat census in considerable by length underground systems (29 and 11 km correspondingly) in Ukraine. Examination of GMN-mines took 77,5 man-hours; IVK-mines, ca. 50 manhours. The obtained results will be at a base of the further bat monitoring in these two sites.
