古岩溶聚煤无论在我国的南方或北方煤田中均具有重要的经济价值。蒲白矿区10号煤层位于太原组含煤系的底部,其成煤作用与赋存形态均受奥陶系古岩溶的控制。该煤层储量约占矿区总储量的10%,个别情况下可占一个井田储量的30%以上,因此,在煤矿设计和生产建设过程中应与5号主采煤层一并考虑开发利用。本文的目的在于通过对古岩溶的研究,讨论10号煤层的赋存条件,以期引起对该煤层的认识和储量的开发利用。
Ancient karst coal accumulation in both China’s northern and northern coal fields have important economic value. The No.10 coal seam in Pu Bai mining area is located at the bottom of the coal-bearing system of Taiyuan Formation, and its coal-forming activity and occurrence are controlled by Ordovician paleokarst. The coal seam reserves account for about 10% of the total reserves of the mining area, and in some cases can account for more than 30% of the reserves of a field. Therefore, development and utilization should be considered together with the main coal seam No. 5 in the design and production of coal mines. The purpose of this paper is to discuss the conditions for the existence of No. 10 coal seam through the study of paleokarst so as to arouse the understanding and exploitation of this coal seam.
