摘　　要：阐述了松软破碎厚煤层顺槽沿顶板布置的“锅底”状放顶煤工作面的优缺点,介绍了三机配套过程中应重点关注的卧底量等配套尺寸,提出了减少支架架间漏矸的措施,并对提高顺槽底煤回收率提出了初步解决方案,可为类似煤层放顶煤开采提供借鉴。Elaborated on the advantages and disadvantages of the pot-bottom type top coal caving working face arranged along the roof in soft and fragmented thick coal seam,introduced the bottoming amount and other matching dimensions that should be focused on during the three-machine matching process,proposed measures to reduce the inter-spalling of support,and put forward preliminary solutions to improve the recovery rate of bottom coal in the inclined drift,which can provide reference for similar coal seam top coal caving mining.
