Excerpt
INTRODUCTION: This report summarizes the results of continuing tests on collision warning systems for surface mining equipment at the National Institute for Occupational Safety and Health (NIOSH), Spokane Research Laboratory (SRL). Collision warning systems currently use one of several methods, including radar, radio-frequency-signal detection, or ultrasonic signals, to detect and warn of the presence of an object or person in the blind spots of the mining equipment. Phase 1 tests are described in a NIOSH Report of Investigations (RI) entitled “Test Results of Collision Warning Systems for Surface Mining Dump Trucks” [Ruff 2000]. Detailed descriptions of the technologies and other background information are presented in that report. One goal of the phase 1 tests was to narrow the number of collision warning systems to be tested in an operating surface mine because time constraints would not allow all systems to be tested. The final selection was based on whether or not the system (1) was available off the shelf, (2) had positive test results and adequate detection areas, and (3) was packaged for...
