It shall be the duty of the Authority to carry out its functions under Part II of this Act in the manner that it considers is best calculated to secure, so far as practicable—
that an economically viable coal-mining industry in Great Britain is maintained and developed by the persons authorised by virtue of that Part to carry on coal-mining operations;
that such persons are able to finance both the proper carrying on of the coal-mining operations that they are authorised to carry on and the discharge of liabilities arising from the carrying on of those operations; and
that persons to whom obligations are owed in respect of subsidence damage caused at any time (whether before or after the passing of this Act) do not sustain loss in consequence of any failure by a person who is or has been a licensed operator to make such financial provision for meeting present and future liabilities as might reasonably have been required of that person.
Subject to section 4 below, it shall be the duty of the Authority, in carrying out its functions under Part II of this Act, to have regard to the desirability of securing—
that persons authorised by virtue of that Part to carry on coal-mining operations are persons who have at their disposal such experience and expertise in the carrying on of such operations as are appropriate for ensuring that any authorised operations are properly carried on; and
that competition is promoted between the different persons carrying on, or seeking to carry on, coal-mining operations.
It shall also be the duty of the Authority, in carrying out its functions under Part II of this Act in cases where it appears that subsidence damage may be caused to any land or other property that does not consist in unworked coal or in a coal mine, to have regard—
to the extent of the damage which is likely to be caused; and
to the character of the land or other property in question and to the uses to which it is or is likely to be put.
