十月煤炭生产联合公司十月革命60周年矿井的捷鲁诺联合采煤队,长期来取得了显著成效。该采煤队开采地质条件复杂的《日丹诺夫斯卡娅》矿井的东7号工作面。m_3号煤层有煤和瓦斯突出以及煤尘爆炸的危险。煤层厚度1.09米,采高1.14米,倾角16°。直接顶是由中等稳定的砂页岩(厚2.5—4.8米)构成。局部地区完全由砂岩构成(1.6—2.2米);老顶由砂质粘土页岩(3—8米)组成。底板为稳定的砂岩,与煤层相接触的是厚0.3米的松软页岩。 The Serunoo United Coal Mining Team at the mine in October, the 60th anniversary of the coal production conglomerate October Revolution, has achieved remarkable results over the long term. The coal team is mining the geologic conditions of the complex “Zhdanovskaya” mine east face 7. Coal seam m_3 has coal and gas outburst and coal dust explosion danger. Seam thickness of 1.09 meters, mining 1.14 meters high, dip 16 °. Direct top is made of medium stable sand shale (2.5-4.8 m thick). The local area is entirely composed of sandstone (1.6-2.2 m); the top consists of sandy clay shale (3-8 m). The bottom plate is a stable sandstone, with soft shale 0.3 m thick in contact with the coal seam.
