(2) The decree does not apply to:
(a) the treatment and processing of minerals carried out in connection with their conquest;
(b) the extraction of sand and gravel in watercourses by floating machines, including the treatment and processing of such raw materials in connection with their extraction;
(c) construction and reconstruction of civil engineering networks at depths up to 10 m, where the depth of the underground entrance does not exceed 50 m and the lifetime (from the time of commencement to the end of construction) of each section, one year;
(d) stamping of connections to civil engineering networks;
(e) underpass entry,

The documentation management shall in these cases be governed by a separate Regulation (1).
Responsibility for documentation management
(1) An organisation in a mining or mining activity (hereinafter referred to as "the activity referred to in Article 1") is required to ensure the completeness of the documentation and the professional performance of the mine metering work under this decree.
(2) The organisation manager (race mine or quarry) shall be responsible for the proper performance of the mine-measuring activity under this decree.
(3) The accuracy and completeness of the documentation produced and its professional management are the responsibility of the worker (hereinafter referred to as the "main mine meter"), which is confirmed by his signature.
(4) The accuracy and completeness of the individual measurements and parts of the documentation shall be the responsibility of the worker who carried out or managed these works (hereinafter "mine meter '), which shall be confirmed by his signature.
(5) The expert authorised by the organisation shall be responsible for keeping the special content of special-purpose mining maps on a mine-based basis, as confirmed by his signature.
(6) The main mine meter decides to take the documentation produced by another organisation or organisation into the documentation file.
Main mine meter
The requirements for professional qualifications and competence to perform the function of the main mine meter are laid down in the Decree on the requirements for professional qualifications and competence in mining or mining activities (3).
Mine meter
The requirements for professional qualifications and competence to perform the functions of a mine meter shall be laid down in the Decree on requirements for professional qualifications and competence in mining or mining activities (3).
Withdrawal of a certificate of competence
Following the identification of deficiencies in the performance of the duties imposed by this Decree, which could result in a threat to the life, health of workers or an immediate danger to the operation of the organisation, the State Mining Authority shall withdraw the certificate of competence from the holder or suspend it until the examination of the worker who caused the deficiencies is carried out at the earliest three months after the date of withdrawal of the certificate.
