奥斯特拉夫—卡尔文煤田有16座煤矿在采煤,这些矿井每年产煤2300万吨,或者说占捷克烟煤总产量的88％。1985年该煤田配备液压支架的综采工作面采煤1420万吨,或者说占总产量的61.8％,配备单体液压支柱的机采工作面采煤近700万吨,占总产量的30.4％。煤田矿山地质条件很复杂,有大量的极薄煤层(0.7m以下)和急倾斜煤层,厚煤层里采区厚度变化不一。此外,煤层有冲击地压危险,采深亦很大。 煤田的矿井和其他矿企业在组织上联合成《奥斯特拉夫—卡尔文煤矿》公司,该公司设在奥斯特拉夫市,该公司还包括有制造煤矿机械和矿用设备的《奥斯特洛依》联合企业(该企业位于奥巴夫市)。
Sixteen coal mines are being mined in the Ostrav-Calvin coal field, which produces 23 million tons of coal per year, or 88% of total Czech coal. In 1985, the fully mechanized coal mining face with hydraulic support coal mining coal 14.2 million tons, or 61.8% of the total output, equipped with single hydraulic props mining face nearly 7 million tons of coal mining, the total output of 30.4% . Coal mine geological conditions are complex, with a large number of very thin coal seam (0.7m below) and steep seam, thick seam mining area thickness varies. In addition, there is a risk of rock burst, mining is also great. The coal mines and other mining companies in the coalition are organically federated to form the company “Ostrav-Calvin Coal Mine”, based in Ostrav, which also includes “Oosse, which manufactures coal mining machinery and mining equipment, Troy ”joint venture (the company is located in Obaaf).
