2023 Arizona Revised Statutes › Title 27 - Minerals, Oil and Gas › § 27-360 - Precautions against flooding

27-360.
Precautions against flooding
A. When advancing a drift,  adit,  level or incline toward a mine working that appears to be filled with water,  a bore hole shall be kept at least twenty feet in advance of the breast of the drive and also,  if necessary,  in directions laterally from the course of the drive. The working place shall not exceed ten feet in width and further measures shall be taken which are deemed necessary by the inspector to obviate the danger of a sudden breaking through of water. No raise shall be allowed to approach within ten feet of a portion of a winze or a stope in which there is a dangerous accumulation of water,  unless the winze or stope is first unwatered by bailing or pumping,  or by means of a bore from the raise. When in the opinion of the inspector there is danger of a sudden inrush of water,  additional raises,  drifts or other workings shall be constructed as necessary to insure escape of persons from the lower workings. Places for the storage of water in mines shall be constructed to prevent leakage as far as possible and insure the safety of the persons working below them.
B. It is unlawful for an operator to impound water or keep water impounded within a mine in which persons are working below the water so impounded in a manner which endangers the safety of the persons unless the water is impounded by a dam or wall approved by the inspector.

B. If an operator of such mines fails or neglects to provide for drainage,  and by reason of failure or neglect the operator of an adjacent or contiguous mine is compelled to pump,  drain or otherwise provide for the water flowing in from the other mine,  the operator of the mine in default shall be liable for the proportion of the actual and necessary cost and expense of pumping,  draining or otherwise providing for such water.
