THE MINERAL INDUSTRY OF KANSAS 331 
 
ating units are coal and gas fired. The air control system on the existing
unit is expected to be in operation in autumn of 1968, With its completion
in 19,71, the 
$37 million, 430,000-kilowatt system will be the largest single generating
unit in Kansas. When using coal as its main fuel source, it will burn as
much as 4,000 tons of southeastern Kansas coal daily. 
 Owing to the gap between crude oil production and demand in Kansas, the
Skelly Oil Co. will build a 135-mile, 8inch pipeline from Cushing, Okla.,
to its refinery in El Dorado, Kans. The line will 
deliver 20,000 barrels of Texas and Oklahoma crude oil to the refinery daily.

 Employment and Injuries.—According to the Employment Security Division
of the Kansas Department of Labor, average annual employment in the crude-petroleum
and natural gas production industries in 1967 was 10,200, compared with 11,000
in 1966. According to the Workmen's Compensation Commission, State of Kansas,
740 on-the-job injuries occured in the mining industry in 1967. Of the 11
fatalities, 10 occurred in the crude petroleum and natural gas industries
and one in nonmetallic mining and quarrying.

 Legislation and Government Programs. 
—The Kansas Legislature passed a oil field unitization law which empowers
the Kansas Corporation Commission to approve a unit that has the agreement
of at least 75 percent of both working and royalty interests. The ktw should
be particularly helpful in establishing workable secondary recovery projects.

 Also passed by the Kansas Legislature were laws pertaining to underground
mining and open-pit coal mining. House Bill No. 1212, pertaining to underground
mining, provides for maintenance of the ground surface contour, subsurface
support of public streets, roads, highways, and other public properties,
and notice of mining activity to future purchasers of surface ground. House
Bill No. 2003, per- 
taming to open-pit coal mining, sets forth requirements for reclaiming mined
areas, and creates a conservation and reclamation board for the purpose of
enforcing this act. 
 The Kansas Corporation Commission rejected a proposal for computing Hugoton
allowables on the basis of field reserves rather than on potential production,
but directed that a committee be named to study the allowable setup and other
field problems. The panel will be composed of firms with a major interest
in Hugoton development and a consultant to represent the Kansas Corporation
Commission. 
 Drilling and Exploration.—During 1967, operators drilled 1,271 exploratory
wells to discover 202 new oilfields and 67 gasfields. Some of the more productive
