Abstract: Basic principle, system engineering arrangement, basic method of data acquisition and analysis,process management of advanced prediction of TRT chromatography scan advance forecast system were introduced; application values of TRT technology in roadway advanced prediction were analyzed, as a new type geological forecast method, TRT technology had advantages like simple, low interference to construction and low cost, relatively accurate advanced prediction could done to water content and crushing rock structure, mined-out area and roadway, etc.

Key words: TRT, Advanced prediction, Process control, Goaf, Water prevention and control, Deep development
