金属矿山巷道支护标准化设计方案的分析与建立

Analysis and Formation of Standardized Design Scheme for Roadway Support in Metal Mines

文章通过对四儿沟门金矿现有的支护手段及其作用原理进行分析,结合支护等级指标RQ值,利用FLAC^(3D)软件建立巷道分级支护数学模型,对各种类型的巷道支护参数和支护效果进行定量分析,制定了四儿沟门金矿巷道分级支护标准,为各种类型巷道的最优支护方案的选择提供依据。

This paper analyzes the existing support methods and their working principles in Si’ergoumen Gold Mine, uses the FLAC3 D software to establish a roadway graded support mathematical model in conjunction with RQ value, the support grade index. Based on the quantitative analysis of the supporting parameters and supporting effects of various types of roadways, it developed the graded support standard for the roadway of Si’ergoumen Gold Mine, which provides the basis for choosing optimal supporting scheme for various types of roadways.
