《罗斯托夫》煤炭联合公司拥有33对矿井,年产量为1970万吨。矿井开采8层煤,厚度为0.55～1.4米。现产生矿井的煤炭储量为6亿吨。煤炭储量和产量取决于煤层厚度,其分布情况如下; 煤层厚度 占总储量％占产量％ 小于0.7米 42.5 10.0 0.71—1.00米 39.8 31.9 1.00—1.2米 10 17.6 大于1.2米 7.7 40.5 煤层倾角0—70℃,急倾斜煤层部分占储量的5.5％,其产量占总产量的2.1％。 煤层基本上采用浅截采煤机开采。目前有71.1的煤是从综合机械化工作面开采的。刨煤机采煤的比重占25.1％,其中有液压支架工作面的占21.2％。 运用新型高效采掘机和适当改造其它工艺,可实现集中生产。因此,1982年矿井日
Rostov Coal has 33 mines with an annual production of 19.7 million tons. Mine 8 layers of coal mining, the thickness of 0.55 to 1.4 meters. The coal reserves of the existing mines are 600 million tons. Coal reserves and output depend on the thickness of the coal seam, the distribution of which is as follows; coal seam thickness% of total reserves% of production less than 0.7 m 42.5 10.0 0.71-1.00 m 39.8 31.9 1.00-1.2 m 10 17.6 more than 1.2 m 7.7 40.5 coal seam dip 0-70 ℃, steep coal seam part of the reserves accounted for 5.5% of its total output of 2.1%. The coal seam is basically mined by shallow-cut shearer. At present, 71.1% of coal is mined from an integrated mechanized face. Plow coal mining accounted for 25.1%, of which hydraulic support face accounted for 21.2%. The use of new and efficient mining excavators and appropriate transformation of other processes, enabling centralized production. Therefore, the 1982 Mine Day
