285The Mineral Industry of Kansas This chapter has been prepared under a cooperative agreement between the Bureau of Mines, U.S. Department of the Interior, and the State Geological Survey of Kansas for collecting information on all minerals except fuels. By Bernadette Michaiski' and Lawrence L. Brady2 Kansas mineral production by value totaled $584.5 million in 1972, a decline of less than 1% from the $589.4 million in 1971. This decline in total mineral production value is the first experienced since 1968. Both declines were largely attributable to a reduction in petroleum production, a commodity that constituted 52% of the total mineral production value in 1967 and 44% in 1972. Other mineral commodities produced in Kansas, listed in order of descending value, include natural gas, natural gas liquids, cement, helium, stone and salt. Mineral fuels and related products contributed about $487 million or 83.3% of total value of mineral production. The remainder was attributable to the nonmetallic minerals industry. Trends and Developments.—Important trends in Kansas include the strong increase in recent years in cement production and the continued decrease in the amount of petroleum produced. Natural gas appears to have reached its maximum production and now is starting a slow production decline similar to that of petroleum. Other commodities during 1972 showed only small variations in the quantities produced from previous years. However, increases in unit value of products, especially natural gas and natural gas liquids, continue to show strong advances. Contracts awarded for highway construction by the Kansas Highway Commission totaled $86.6 million for 1972. This was a drop of approximately $15 million from the record contract year of 1971. Several major highway improvements were opened in 1972 including a 23 mile segment of interstate highway between Newton and McPherson; construction of 2.3 miles of viaduct above the Wichita street system; 49 miles of freeways; and 31 miles of new two-lane roads. In 1972, Kansas abandoned its pay-before-you-build approach to State highway construction and adopted bond financing to build a proposed freeway system. Kansas Highway Commission officials indicated that this change resulted from a legislature decision in 1970 that designated nine freeway corridors totaling 1,234 miles, and allocated a portion of highway funds exclusively for freeway construction. Financing was changed and now 20% of net gasoline tax revenues is being used to support interest and principal payments for land. Under terms of the law, the Highway Commission has sold two $40 million issues of highway bonds of the $320 million authorized over an 8 year period. A limestone scrubber system for the new 430,000 kilowatt powerplant in Lawrence continued to undergo tests during 1972. The system utilizes finely ground limestone that is injected into the boiler along with the coal. One major change in the design involves the raising of the point of limestone injection into the boiler above that of the coal injection level. In the original design the coal and limestone were injected into the boiler at the same level. This resulted in extensive caking of the lime product on the boiler walls. Assembly of the $34 million limestone scrubber unit at the new coal-fired La Cygne powerplant continued in 1972. Testing of this large unit will be initiated in 1 Mineral specialist, Division of Fossil Fuels— Mineral Supply. 2 Geologist, State Geological Survey of Kansas, University of Kansas, Lawrence, Kans.
