目前,世界各地普遍使用两柱掩护式液压支架,液压支架技术水平也逐渐也成反映国家煤机装备水平的重要指标。本文先简单介绍液压支架的特点,并重点以实践工作经验探讨整体下井运输受限条件下,如何优化两柱掩护式液压支架的设计,以满足该架型满足整体下井矿井提升要求,以加速我国煤炭事业的持续发展作出参考意义。 At present, two columns of hydraulic shields are commonly used all over the world, and the technical level of hydraulic supports gradually becomes an important index reflecting the level of national coal equipment. This paper briefly introduces the characteristics of the hydraulic support, and focuses on practical experience to explore the overall under the conditions of transport constraints, how to optimize the design of two-column shield hydraulic support to meet the requirements of the overall shaft to enhance mine shaft to speed up China Coal sustainable development for reference.
