摘　　要：根据公务素地区16#煤层赋存条件,运用工程类比法和数值计算法给出16#煤层顺槽的基本支护方式和支护参数,并将其应用于公务素煤矿二号井北一综放面回风顺槽和相邻工作面运输顺槽围岩稳定性控制的工程实践中。结果表明,所设计的锚固参数可确保综放面采动过程中上下顺槽的稳固性,且预掘巷道时上下工作面顺槽煤柱宽度可由20 m减小到15 m。Based on the occurrence condition of No.16 coal seam in Gongwusu areas,the basic support patterns and support parameters for the gateway in the coal seam were given out by use of engineering analogy method and numerical calculation method,and were applied to the stability control engineering of surrounding rock of the air return gateway in the north 1st fully-mechanized coal mining face and the transportation gateway adjacent to the aforementioned working face in the 2nd Well of Gongwusu coal mine.The results showed that the stability of the upper and lower gateway during the mining of the working face can be ensured under the design of the anchoring parameters,and the width of the coal pillar between the upper and lower pre-driven tunnel should be reduced from 20 m to 15 m.
