Abstract:
In view of the existing problems of large difficulty in roof management, poor equipment coordination, low production efficiency and others in thin coal seam mining, taking the 10106 fully mechanized mining face of Sendayuan Coal Industry Company as the research object, an optimization scheme for thin coal seam fully mechanized mining face process based on intelligent centralized control is proposed. This scheme constructs a hierarchical distributed intelligent control system architecture, which achieves shearer bidirectional memory cutting, bracket automatic follow-up and movement, and intelligent linkage of the three machine equipment. In the aspect of process parameter optimization, a coal cutting way of "small footage, fast speed" and a bracket moving strategy of "closely following fast movement" are adopted. A roof intelligent control model based on the working resistance of the bracket is established, and a transportation system intelligent scheduling algorithm is developed. According to the production data statistics for three consecutive months, the daily yield of the working face after optimization is steadily improved to 1890 tons, with a per capita efficiency reaching 25.7 tons/worker, and the energy consumption per ton of coal is decreased to 35.8 kilowatt hours/ton.
