  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
