Abstract

The main objective of researches was the analysis of experience of application of technological schemes of mining of longwall panels without re-installation of the equipment of a coal face. For conditions of the mine Taldinskaya-Zapadnaya-2 change of coal face output when mining longwall panels with a longwall turn is shown. Sharp decline in output of a longwall at a face turn is shown. Comparison of efficiency of mining of longwall panels with a turn of a complex and at re-installation of a longwall is executed. Recommendations about decrease in equipment downtimes and increase in efficiency of re-installation of the equipment of a longwall are made.
