Abstract

An automatic height adjusting apparatus and method for a shearer based on advanced detection of a shearer seismic source. The apparatus comprises a shearer-side signal acquisition device, a workface-side signal acquisition device (2), and a height adjustment control module. The shearer-side signal acquisition device acquires a seismic source signal of a shearer (1), and resolves absolute orientation parameters of the shearer (1) in a mine coordinate system and geographic coordinates of upper and lower roller centers of the shearer (1). The workface-side signal acquisition device (2) acquires the seismic source signal of the shearer (1) after the same has been reflected by a wave impedance interface and resolves absolute orientation parameters of the body (2-1) in the absolute mine coordinate system. The height adjustment control module automatically adjusts, according to a received signal, the height of upper and lower rollers of the shearer (1).
