【 摘 要 】

The development of the crosscut from the aspect of mine surveying is a specific task, since there is no possibility for an independent control of its construction during the development. This is primarily related to the long crosscuts where the deviations of the designed direction of crosscut would have significant consequences on safety and technological activities in the mine shaft. In order to avoid errors, it is necessary to perform the preceding analysis of the crosscut accuracy, where the overall standard deviation of the crosscut is calculated. This value must be smaller than the given allowed deviation. The paper presents an a priori evaluation of the accuracy of the crosscut to be developed in the brown coal mine 'Soko' for the purpose of ventilating the opening rooms of the eastern part of the deposit.
