Excerpt from Twenty-Third Annual Report of the State Inspector of Coal Mines, 1935 The report on the coal industry for Colorado for 1930 is very gratifying as it shows a substantial increase in production over 1934 and a trend towards better times. Colorado produced tons of coal during the calendar year of 1935, which represents an increase of tons over the year of 1934. This tonnage was produced by 367 mines employing an average number of miners and other employees who worked man-days, an increase of 272 men and man-days over 1934. There were 342 companies and individual operators reported. With very few operators working more than one mine. The 1934 production was approximately 42% of that produced in 1918 which was the peak year in the coal industry of Colorado. Since 1929 the production dropped steadily until this year, which showed an increase as above stated. The great decrease in production also diminished the revenue which is necessary to maintain this department. To overcome this loss in revenue, new legislation was enacted by the Thirtieth Gen eral Assembly requiring all coal mines to take out an annual license. Mines producing 500 tons or less annually pay a fee. Mines producing in excess of 500 tons and less than tons pay an annual fee of All mines producing in excess of 1 000 tons annually must procure a license. Three hundred Sixty licenses to operate a. Coal mine were issued to mines producing from 20 tons of coal annually, to the largest which produced tons of coal during 1935. Seven mines closed either prior to the law going into effect or were closed for failure to get a. License. Of the 367 mines reporting only 76 have railroad connection, the balance being served by trucks and wagons. The number killed in and around mines was 26 men, 4 of whom were killed in the Bear Canon mine explosion in Las Animas county. There were injuries reported. Detailed ratings of injuries and deaths are recorded in the tables of this report. A number of new names appear in the list of mines reported herein. They do not all represent new mines. In most cases they are old mines reopened under new names by new Operators. How ever, in cases where the mines have changed hands the old names were retained unless the operator insisted on the change.

Excerpt from Fourth Annual Report of the State Inspector of Coal Mines, 1916 The condition of the coal industry for this year shows marked improvement over the preceding year, both in production, market price and wages paid. The production amounted to tons. Fourteen of the nineteen coal-producing counties contributed to the increase, which was tons; tons of the total was in run-of - mine, the bulk coming from Las Animas County. This was used at the-steel works, either as coal or in the form of coke. The coke production amounted to tons, an increase of tons, ' compared with the preceding year. The selling price of coal advanced materially in the fall of the year, and the workers have received an increase in wages. The monthly and annual reports from the Operators, with few exceptions, are so incomplete that it is practically impossible for this department to give the full information required by law. The Federal Government has adopted a standard for mining statistics, a Copy of which is hereto attached. The principal object of this is to make all coal mine inspection reports uniform, and to eliminate duplicate reports now made by the mine owners to the different state and federal institutions. The monthly and annual report forms furnished the Operators by this department have been changed to conform with the federal requirements. The attention of the operators is drawn to the importance of filling in all details of the aforesaid reports, in order that this department may comply with the new statistical requirements. It will no longer be neces sary for operators to report non-fatal accidents to this department, as arrangements have been made to get this information from the Industrial Commission. Fourteen proposed amendments to the mining law are now being considered by the legislature, the object being to make the law more specific and to conform with the state compensation law.
