Design and Testing of a Continuous Excavator for Surface Coal Mining.
For Reference Only At Bureau Libraries :96 pages
This report presents the results of mining tests conducted on a forward bucket wheel excavator designed to continuously mine coal at 1,080 tons per hour. Goals of the program were to determine the feasibility of the forward rotating bucket wheel principle as an effective means of reducing fragmentation and loading costs associated with surface mining with additional benefits in reducing coal preparation costs and stripping overburden. Results show that the excavator performed as expected and can reduce fragmenting and loading costs up to 80 percent. Production machine design specifications and projected economies extrapolated from the test data and recommendations for further work in dust control are also presented.
