Jednim z hlavnich problemu, ktery pfedstavuje znacne komplikace pri rcalizaci tezebnich praci v nadlozi uhelnych sloji v Severoceske hnedouhelne panvi je vyskyt pevnych hornin, jejichz tezba kontinualni technologii je velmi obtiźna nebo dokonce nemozna. Stanoveni pfesne polohy techto pevnych teles je proto nezbytnym pfedpokladem pro uspesne provadenf techto praci. Jednou z metod, ktere mohou prispet reseni tohoto problemu je urcovani pozice techto teles s vyuzitim technologie plnoprofiloveho vrtani (rotacniho, pfip. rotećne pfiklepneho) pfi soućasnem sledovani zakladnich zadanych a vyslednych parametru reżimu vrtani (tzv. mechanicka karotaź). V ćlanku jsou shrnuty nektere zakladni poznatky, ktere byly ziskany pfi realizaci teto metodiky na Dole Bilina v letech 2007/2008, vcetne pfikladu vyhodnoceni grafickych zaznamu mefici aparatury, ktera byla nateto lokalite nasazena.
Geological drilling exploration represents very important activity necessary to gam information utilizable for the purposes of mining process regulation in the all lignite mining localities of open pit mines in the North Bohemian Basin. Beside the classic methods used for the determination of drilled rocks such as drill core taking, which is otherwise of high quality but very costly, the method of mechanical bore hole logging represents important information source utilizable in drilling process. This method is based on the principle of the observation of basic engaged and final parameters of the drilling process and their evaluation in relation to drilled rocks. This method is available especially in the areas typical of expressively different of drilled rocks. It is possible to use this method in conditions of the coal bed's hanging wall in the mining localities of open pit mines in the North Bohemian Basin, distinguished by typical presence of solid rocks with a markedly different rocks' solidity in comparison with adjacent rocks in the coal bed's hanging wall. The methodology listed above was field tested and evaluated in mining conditions of the Bilina mine.
