煤巷锚杆支护初始设计新方法研究

Analysis of New Design Method and Application of Bolt Support in Coal Roadway

关于煤巷锚杆支护设计传统方法多以工程类比法与理论分析法为主。然而,当前采用这两种设计方法已经难以适应当前煤巷支护实践作业多元化应用需求。因此,结合西山煤电矿区——镇城底矿南一下组采区井皮带巷工程作为实例,对其皮带巷锚杆支护设计采用的数值模拟设计新方法进行了简单分析,以期为业界人士提供一定考量依据。

The method of analyzing coal roadway bolting design method in traditional engineering is analogy methodand theory. However, the current use of these two design methods have been difficult to adapt to the current coalroadway supporting practice diveified applications. Therefore, combined with the Xishan coal mining area, a group ofsouthern Zhenchengdi mine belt roadway engineering mining wells as an example, to support design by numericalsimulation of the belt roadway bolt design method to a shallow analysis, in order to provide a basis for the considerationof the industry.
