摘　　要：矽卡岩水理性较强,当矽卡岩遇水时力学性能变化较大,会给矿山的安全生产带来不利影响。利用数值模拟软件对某铁矿山矽卡岩岩体中的不同巷道支护方式进行了数值模拟,探讨其巷道变形及安全系数的变化规律,特别是引入了锚喷加锚杆联系链的支护方式,通过数值模拟结果的数据分析比较,得出锚喷加锚杆联系链的支护方式对巷道的稳定性最有利。Skarn has a strong hydraulic property.When skarn meets water,its mechanical properties change greatly,thus bringing adverse effect on the mine safety production.The numerical simulation of different tunnel support in skarn rocks for a iron mine is made by using numerical simulation software to explore the tunnel deformation and the variety of safety coefficient.Especially the shotcrete and bolt connecting chain support is introduced.Comparing and analyzing the numerical simulation data,it concludes that the shotcrete and bolt connecting chain supporting is the most favorable way to keep the stability of the tunnel.
