锚杆支护已成为深井巷道围岩控制的主要形式,支护效果的好坏除与所采用的支护方式有关外,还与围岩性质、开采条件有关.为准确评判回采巷道锚杆支护效果,以平顶山矿区深部回采巷道为研究对象,选取32条回采巷道为样本,依据围岩强度、支护强度、巷道埋深、围岩完整性、采动影响、巷道断面、煤柱宽度等7个指标,采用模糊聚类分析的方法将巷道围岩支护效果分成好、较好、一般、差4类.据此对新掘巷道给定条件下的支护效果进行预判,为锚杆支护参数确定提供依据.
Bolting support has become the main form of surrounding rock control in deep mine roadway, and the support effect is good or bad except related to the support method adopted, but also relates to the nature and mining conditions of surrounding rock.In order to accurately judge the bolt support Based on the surrounding rock strength, supporting strength, the depth of roadway, the integrity of surrounding rock, mining influence, roadway section, coal pillar width and so on 7 indicators, the method of fuzzy clustering analysis is used to divide the support effect of roadway surrounding rock into good, good, general, poor 4. Based on this, the support effect under the given conditions of new roadway is predicted, Rod support parameters to determine the basis.
