摘　　要：利用模糊综合评价理论和现场实测数据,对隧道掘进中常用的6种掏槽方式及参数进行优化评价,评价结果表明,楔形掏槽的掏槽效果最佳,而在直眼掏槽中,三角柱掏槽、螺旋掏槽的掏槽效果较好。结合现场实际情况,推荐三角柱掏槽、螺旋掏槽和双空孔菱形掏槽3种方式更适用于隧道掘进深孔爆破中,同时,这对进一步优化掏槽方式及其参数具有理论和现实意义。The method of fuzzy theory is developed for optimization of six undermine patterns and relative parameters. The observation data are adopted for optimization. The results show that the best undermine pattern is the wedge cut pattern. In the burn cuts, the better patterns are the compound cut and spiral cut. According to the actual result, the compound cut, spiral cut and diamond burn cut are recommended in the deep blasting.
