  9. Power to do work for discovering
  (1) The Central
  
  Government may, subject to the provisions of this section, do on, over or below
  
  the surface of any land such work as it considers necessary for the purpose of
  
  discovering whether there is present in or on the land, either in a natural
  
  state or in a deposit of waste material obtained from any underground or
  
  surface working, any substance, from which in its opinion any of the prescribed
  
  substances can be obtained, and the extent to which such substance is so
  
  present.
  (2) Before any powers
  
  are exercised under sub-section (1) in relation to any land, the Central
  
  Government shall serve on every owner, lessee and occupier of the land a notice
  
  in writing specifying the nature of the work proposed to be done and the extent
  
  of the land affected, and the time, not being less than twenty-eight days,
  
  within which and the manner in which objections can be made thereto, and no
  
  such powers shall be exercised otherwise than in pursuance of the notice or
  
  before the expiration of the time specified therein for making objections.
  (3) The Central
  
  Government may, after giving the person making the objection an opportunity of
  
  appearing before and being heard by a person appointed by the Central
  
  Government for the purpose, and after considering any such objection and the
  
  report of the person so appointed, make such orders as it may deem proper but
  
  not so as to increase the extent of the land affected.
  (4) Compensation shall
  
  be determined and paid in accordance with section 21 in respect of any
  
  diminution in the value of any land or property situate thereon resulting from
  
  the exercise of powers under this section.
