Development,Installation,and Testing Services for an Automatic,Point Type Thermal Sensor,Fire Protection System on a Mining Dozer.

摘要

Lease AFEX,Inc.,modified its standard design of an automatic fire protection system used in the past on logging equipment,and long-term,in-mine tested system on a Fiat-Alli's HD-41B dozer at the Lemmons and Company coal mine, Boonville,Ind. The modification of the standard AFEX system involved improving the actuation device. The AFEX system is called a point-type thermal sensor,automatic fire protection system. The in-mine test took place in late 1975,and early 1976. The system was then tested by simulating a fire on the dozer. The system operated successfully after the 4months of in-mine endurance testing.
