Deep High Stress Surrounding Rock Control Technology in Roadway Driving Along Goaf
Abstract：As the extension of mining and increasing complexity of engineering geological environment,supporting is more and more difficult.In order to better address the deep caving driving gob of supporting issues,on the basis of the stress test and rock mechanics testing,analyzed the deformation mechanism of caving along goaf,and by numerical calculation,the combination of theory and engineering research methods analogy,determined the reasonable width of the narrow pillars,supporting programs and parameters.Engineering results show,the integrated research approach controlled the driving gob-rock deformation effectively,and provide a theoretical basis and technical approach.
