运用数值模拟、试验采场现场监测对小官庄铁矿上向进路充填采矿方法的断面形状和进路尺寸参数进行了研究。对矩形、半圆拱、三心拱、六边形等4种典型断面进行了应力应变模拟计算,从进路周围塑性区分布、主应力差分布以及位移变形分布3方面进行分析,结合试验采场位移监测数据,认为合理的断面为六边形；针对进路尺寸参数的高度、宽度、长度3个因素对采场的影响,通过最大主应力、最小主应力、竖直方向位移正交数据表的分析,得出最优的参数为进路宽度3．5 m、进路高度3．5 m、进路长度60 m,该参数在现场得到了成功的应用。研究成果对小官庄铁矿的充填采矿方法结构设计提供了理论指导,并对类似矿山具有借鉴意义。

With application of the numerical simulation and the field monitoring,the sectional shape and dimension pa-rameters of upward drift in Xiaoguanzhuang Iron Mine are investigated. Stresses of four typical drift cross-sections are simula-ted,including rectangular,semicircular arch,three heart arch and hexagon section. According to the distribution of plastic zone, principal stress difference and displacement deformation around the drift,the hexagon section is chosen as the most reasonable section shape,combining with the displacement monitoring data in testing stope. According to the effects of drift height,width and length on stope,and through analyzing orthogonal tables including the maximum principal stress,the minimum principal stress and vertical displacement,the optimum parameters of drift are determined as width 3. 5 m,height 3. 5 m and length 60 m,which have been successfully applied in field mining. These researches provide theoretical guidance for the design of the fill-ing mining in Xiaoguanzhuang Iron Mine,and provide reference for similar mines.
