Abstract
The paper evaluates surface coal mining in the Dal'vostugol' association. Five surface mines of the association mined 13.8 Mt in 1980, 105,900 m/sup 3/ of overburden were removed, overburden to coal ratio was 7.67 m/sup 3//t, labor productivity per miner was 663 t/month, mining cost 2.70 ruble/t. Use of powerful walking draglines for mining, overburden removal and spoil bank formation influenced mining schemes and permitted labor productivity to be increased. Mining schemes without transport of overburden are shown . The following types of mining equipment were used: EhSh-15/90, EhSh-14/75, EhSh-10/60 and EhSh-10/70 draglines, EhKG-4.6u and EhVG-4I face shovels. Mining and geologic conditions are described: climatic conditions are characterized by intensive temperature fluctuation. Air temperature in January ranges from minus 26.8 C to minus 41.0 C and in July from 7.2 C to 31.9 C, the annual precipitation is 622 mm. Thickness of frozen soil in winter ranges from 2.5 to 3.0 m. Geologic conditions of the basin are analyzed: coal seam thickness, depth, coal properties, ash, sulfur, volatile matter, moisture, calorific value, stratification of overburden, mechanical properties of overburden, ground water and water influx. Operation of the Dal'vostugol' mines is described on the example of the Severo-Vostochnyi surface mine, the
