Research on mining methods and equipment selection for large dip coal seams
The mining of large dip coal seams has always been one of the major challenges faced by coal mines,seriously affecting the efficiency and benefits of coal production.The research on the geological structure,mining methods,equipment selection,and risk pre-control of large dip coal seams was conducted,the systematic technical specifications and construction plans were designed and formula-ted to improve the mining efficiency of large dip coal seams and ensure the safe and continuous production of the working face.Taking the No.12901 working face of the large dip coal seam in Zhangshuanglou Coal Mine as an example,by revealing the manifestation law of mining pressure in the large dip coal seam,and based on the thickness of the coal seam,geological characteristics,and technical charac-teristics of existing mining methods,a reasonable mining method and equipment were determined,indicating the effectiveness and supe-riority of the research plan.
