基于加权平均评价法的巷道支护设计研究

Research on Roadway Support Design based on Weighted Average Evaluation Method

以经坊煤业3-6012回风顺槽为例,提出了基于加权平均评价法的巷道支护设计方法。加权平均评价法分析煤巷围岩稳定性,确定巷道锚杆支护形式与主要参数,结果表明该支护方案能够有效保障巷道稳定性。

Taking the 3-6012 return air chute of Jingfang Coal Industry as an example,a design method of roadway support based on weighted average evaluation method is proposed.The method of weighted average evaluation is used to analyze the stability of surrounding rock of coal roadway and determine the form and main parameters of roadway bolt support.The results show that the support scheme can effectively guarantee the stability of roadway.
