Abstract

The paper studies an automatically heightened technology in the shearer drum. It establishes a mathematical model of spacial status in coal minning mechine, Structures of the coal mining machine test-bed and determines the space coordinates of the shearer drum and its body, in addition it derives the relevant formulas. The cutting path of shearer drum is computed based on the cubic spline fitting. The correctness and feasibility of the proposed method is verified by the computation algorithm with VB6.0 program.
