摘　　要：以石壕煤矿S1632工作面的煤岩层瓦斯赋存参数为基础,建立了顺层钻孔瓦斯抽放数值模拟模型,分别对不同抽放时间的单个顺层钻孔、不同间距的多个顺层钻孔抽放瓦斯后的煤层瓦斯压力分布进行了模拟,模拟结果显示:抽放时间6个月,抽放钻孔布置间距6～8 m时较为合理,并对石壕煤矿S1632工作面顺层抽放参数进行了优化。Based on gas occurrence parameters in the coal bed of Shihao coal mine $1632 working face, the paper established numerical simulation model of bedding borehole gas drainage, and separately simulated the gas pressure distribution after gas drainage of single bedding borehole of different drainage time and multi bedding borehole of different spacing. Simulation results show that drainage time of 6 months is more reasonable to layout the borehole spacing of 6 - 8 m, and the bedding drainage parameters in Shihao coal mine S1632 working face is optimized.
