The paper discusses a research study to recover energy from service or cooling water brought into deep mines. The test site was the Luck Friday Mine, owned and operated by the Hecla Mining Company of Wallace, ID. The selected energy recovery system that was demonstrated was a turbine-generator arrangement. The selection of the turbine-generator system was dictated by the mine arrangement at the Lucky Friday Mine. During the summer of 1984, the system installation was completed and initial start-up tests were conducted to verify performance. During these tests, several problems became apparent which required remedial action to correct. These problems, and test results, are discussed.
