2788 ARTICLE 89.

bituminous coal mines of this State, where intersecting roadways or en-
tries may produce doubt as to the proper direction to the nearest outlet.

1922, ch. 307, sec. 81.

82. Provision shall be made for proper ventilation of shafts while
they are being sunk. Until a second means of outlet becomes available from
every part of any mine worked by shaft, a cage or other safe means of
egress shall at all times be kept available for use of persons within such
mine. During construction or deepening of any shaft, ample provision
shall be made for protection of workmen engaged in such construction or
deepening, against falling or against accidents from caving in or from
materials falling down the shaft. Unless the strata being penetrated are
solid, every shaft shall be lined, cased or otherwise made secure; and the
operator shall direct and see that all loose rock or other dangerous materials
are removed from the sides of such shaft or from any staging or timbers
therein, especially after each blast; and whenever persons are employed
upon platforms in shafts the operator shall see that said platforms are prop-
erly and safely constructed and secured.

1922, ch. 307, sec. 82.

83. The Bureau shall prescribe by regulation for the provision and
maintenance of safety gates or other adequate protective devices at top
and intermediate landings of shafts and steeply inclined slopes; and for
the employment of competent gatemen when in the judgment of the Bureau
such employment is desirable; and defining the duties of such gatemen;
and for the construction and unobstructed maintenance of safety passage-
ways sufficient in area and height for comfort and easy use, at needed
points within such mine; and for indicating and illuminating lights at
such points in such mine, including the bottom of shafts and intermediate
points where cages may stop, as the Bureau may deem desirable.

CHAPTER XII—Hoisting, Power and Apparatus.
1922, ch. 307, sec. 83.

84. The permanent boilers used for generating steam, and buildings
containing the same, shall not hereafter be constructed nearer than sixty
feet to any mine opening or to any building or inflammable structure at
or connected with such opening.

1922, ch. 307, sec. 84.

85. At least once in every six months, and oftener if required by the
district mine inspector, all boilers used for generating steam in or about
any such mine shall be inspected and tested, under regulations of the
Bureau; and a report thereof, upon blanks provided by such Bureau, shall
be made to the district mine inspector and the Bureau by the operator of
such mine. Such report shall state the experience of the person making
the tests, and be countersigned by the mine foreman or superintendent.
