摘要
在华亭矿地质条件基础上,利用数值模拟软件对特厚煤层分层综放开采煤柱的留设和分层巷道布置进行优化计算,得出了较优的区段煤柱尺寸和分层巷道的布置方式。并将所得的煤柱尺寸和实际进行比较,基本满足工程需要。
Based on geological conditions of Huating Colliery, this paper applied numerical simulation software to optimizing coal pillar design and roadway layout of sub-level full-mechanized caving mining extremely thick coal seam. It obtained rational coal pillar dimen- sion and roadway layout manner. Actual application showed the dimension of coal pillar was fit for engineering requirement.
