Design, Fabrication and Testing of a Low Headroom Conveyor Transfer Chute. Final Technical Report

摘要

This document contains the results of tests performed on eight one-sixth scale models of low headroom transfer chutes for underground belt conveyors. The models were evaluated using a methodology technique to select one chute for further full-scale testing in an underground mine. The study concludes that the slide chute should be tested in an underground 90 exp 0 transfer point. The report contains a state-of-the-art survey, a literature search, data from mine visits, test results, evaluation based on the methodology technique, and a set of guidelines for the design of low headroom transfer chutes. Also included are the preliminary designs of the slide and stone box chutes, scaled up from the designs used in the tests. Following the first phase of the program, the contract was terminated for the convenience of the government; therefore, the program did not progress to the Phase II full-scale chute fabrication or Phase III field testing.
