QYJ Ⅲ type fully mechanized mining equipment is made of specially designed domestic equipment, also known as economic mining equipment. The equipment consists of QY200-14 / 31 cover type hydraulic support, MLS_3P-170 double drum shearer, SGWD-180PB single chain scraper conveyor, ZGD-75PB single chain scraper loader, SD-80 retractable belt conveyor , ZD-28 single hydraulic prop, XRB_2B emulsion pump station, XPB250 / 55 spray pump station, KSGZY-500/6 mobile substation, and communication, lighting and high voltage leakage protection devices. Among them, the hydraulic support by the Beijing Mining Institute and Beijing Coal Factory jointly developed, reproduced by the Northwest Coal Machine Plant developed by the identification. The remaining equipment are selected stereotypes products. This set of equipment and supporting the main supporting relations to talk about several points. First, QYJ Ⅲ type fully mechanized mining equipment was in early September 1983, the Ministry of Science and Technology Development Division held in Songzao Mining Bureau of Sichuan Province
