Research On Auxiliary Relative Equipment And Safely Mining Technology Of Slicer Coal Face

This text carried on the industry test and studies through W1W-703 , W1W-712 ,W1W-702 working face of thin coal seam for small blue and green mine, researchedsystematacially suitable technology for thin coal seam mining equipment, confirmedexploitation craft parameter , problem of two tunnel support technology and theventilating administrative skill etc. The author developed new technology jointinterface and control system for German slicer key technology and domesticequipment, succeeded in realizing their related application, developed the end headsupport of new-type special-purpose and electric liquid control system matched. Thusthe end head support operate artificially is substituted by the automatic control systemof slicer. The author proposed and succeeded in implementing the technologicalscheme of " one control three supports ", confirm the scheme of supporting bestly fortwo tunnel, and put forward corresponding ventilation manage measures.Through practical application, it has realized the security , economy , high-outputand high-efficient goal, opened up a best technological way for winning of thin coalseam .
