摘    要:为进一步研究软岩巷道在受采动影响下的围岩松动圈大小及发展规律,为锚杆锚索支护技术提供科学的依据,选取内蒙古鄂尔多斯市高家梁煤矿受采动影响的软岩巷道为研究对象,运用孔壁检视法和地震波反射法联合现场测试,然后用分形理论来预测比较围岩松动圈大小的方法来测定围岩松动圈;现场实测结果表明:受采动影响的巷道的松动圈是一个不断扩展的过程,最终稳定在1.7~1.9m之间,而且用分形理论预测的结果和现场测试的结果几乎相同;该联合测试方法为软岩巷道的支护参数选择提供了依据,为其他类似矿井的松动圈测试提供了一种新方法而且具有重大的指导意义.

关 键 词:软岩  松动圈  孔壁检视法  地震波反射法  分形理论

Abstract:In order to further research the size of released circle and variation regularity of soft rock roadway under the mining influence and provide scientific basis for anchor and anchor cable supporting technology,the paper took soft rock roadway under the mining influence as example,which located on Gaojialiang coal mine in Erdos,Inner Mongolia.It used the combined site test methods of hole wall review and earthquake wave reflection,furthermore applied fractal theory to forecast the size of released circle of surrounding rock.The site test results indicate that the size of released circle is a constantly extended process under the mining influence,and the final range is from 1.7 to 1.9 meters,the predicted results accord well with field test using fractal theory.Therefore,the combined test methods can provide a basis for the selection of soft rock roadway support parameters and supply a new testing method of released circle for the other similar coal mine.
Keywords:soft rock  released circle  hole wall review method  earthquake wave reflection method  fractal theory
