摘要
针对龙口矿区梁家矿“三软”厚煤层综采一次采全高的回采工艺设计，拟选两种支护方式（锚网喷和Ｕ型钢支架）支护回采顺槽，通过技术、经济对比分析选择了前者。生产实践证明，该支护形式无论在技术上还是在经济效益上都是较好的，并对其提出了改进意见。
This paper introduces the mining technology design and supporting pattern selec-tion of fully-mechanized full-soft coal seam cutting face between soft roof and floor and the prac-tical effect of selected support pattern in Liang jia Coal Mine of Long kou coal field. It also putsforward the Suggestions for improvement on this supporting manner.
