Simulation and Optimization of Bedding Borehole Gas Drainage Flow Field in Shihao Coal Mine
摘要
Abstract
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.关键词
