C.R.S.
Section 34-24-102
Coal or other mine maps
(1)
Every operator shall make a map of the surface of the property and a map of the underground workings. Such map shall be updated and submitted annually to the division.(2)
Each map shall be retained by the division in its permanent records. Such records shall be available for inspection, on request, by the public. Maps filed with the division prior to July 1, 1980, shall be made available to the public if the property is abandoned, and such maps shall be made available to the public with permission of the operator if the map depicts a mine which is still in production.(3)
Whenever surface features of a mine property can be shown upon such map without obscuring its details or impairing its usefulness, a separate map need not be made.(4)
Each map shall be made on a scale of not less than one hundred feet nor more than five hundred feet to the inch unless a different scale is approved by the office of active and inactive mines, and such map shall bear the name or number of the mine, its location as to county, township, and section, the name of the company or operator, the north point, the scale to which the map is drawn and an explanatory legend, and the certificate of the engineer or surveyor as to the accuracy of the map.(5)
The underground map shall be made on the same scale as the surface map unless a different scale is approved by the office of active and inactive mines and shall show the mine openings or excavations; the shafts, slopes, and drifts of the mine, the connections with other mines or workings, or any other seams in the same mine; the entries, rooms, pillars, and abandoned workings of the mine; and the barrier pillars between adjoining properties. Each map shall show the elevation of the mine haulageways and cross entries every five hundred feet.
