SIZD OF OVERMAN DISTRICT

Size of Overman’s District
(1) The size of an overman's district shall be so arranged that :
(a) the number of persons of all categories under the charge of the overman does not
exceed 100.
(b) the distance between the first and the last working face is ordinarily not more than 750 m. (2,500 ft.) measured along the inspection route (but not taking into consideration the
travelling done beyond the last ventilating connections for inspecting blind ends);
Provided that when the thickness of the seam is less than 1.5m (5 ft.) or when the workings are steeper than 1 in 5, the said distance may be limited to 450 m (1,500 ft.);
and
(c) the output of the district is not more than 100 tonnes per shift.
Provided that if part of the output is from depillaring area, the said limit of output may be increased to 125 tonnes.
(2) The criteria given in (1) above will not apply to-
(a) a longwall face, which should be under the charge of one overman only in each shift irrespective of the output and number of men employed at the face;
and
(b) the mines in Assam which have specially arduous conditions of work. For these mines the size of an overman's district shall be determined in consultation with the Joint
Director of Mines Safety.
(3) If any variation of the above mentioned directions becomes necessary in any mine due to any reason, the case shall be referred to the concerned Joint Director of Mines Safety.
(4) It is expected that the mine management shall not retrench any overman if he becomes surplus to the requirements of a mine in accordance with the criteria given in para 2
above.
