MODEL TESTS OF LONGWALL SHEARER WITH STRING FEED SYSTEM

This article concerns model tests of longwall shearer with string feed system. The introduction outlined the problem exploitation thin seams, in particular hard coal and briefly described construction operation technology a single-unit system for their exploitation. modeling machines such was presented, as well author’s physical mathematical unitary shearer. Then, assumed parameters, were carried out on dynamics together Comprehensive dynamic wall height range from 1.0 m to 1.6 m, length 180 300 taking into account four dimensions applied chain. As result, number information obtained concerning kinematics shearer, its along wall, translations rotation relation axes loadings nodes. most important part are results tests, which interpretation enable verification optimization selection power feeder drives body.
