Analysis on new mining technique of single thin seam in surface mine

According to the mine with a single thin seam would have a high stripping ratio,a low mining efficient rate in an underground mine,a resource waste and other problems,a new mining technique with a dragline,stacking machinery.shoveling coal shearer in the stripping blocks were provided.Under the technique conditon,the paper systematically studied the mining parameters in the pit bottom,the width and length of the strjpe block,the following distances between the mechanical shovel and the dragline. The mining coal volume connection plan of the stripe block was provided. The transportation system and dragline moving mode in the mining process were optimized and studied.Fild application results showed that in a surface mine wih a single thin seam,a stipe block mining ftechnique with a dragline,stacking machineryshoveling coal shearer wouldhave a high systematic reliability,low production cost,low ground disturbance and other features and could rove the labor and production effiviency and highly recover the mine resources.iA science,environment protection,green and intllient inegratedmining could be realized and would have important significances to enrich and develop the mining theory
