Static and dynamic load analyses of flexible packing under thick hard roof to gob side entry retaining
摘要
Abstract
In order to solve the problem of difficulty in process by lateral roof-broken explosion about gob side entry retaining under thick hard roof, the adaptability of filling in static and dynamic load was researched. So, gob side entry retaining was carried out by roadway-side filling with flexible material (gangue). The influence of the different diameter and lateral support stress to load-carrying properties were analyzed and stress-strain relationship of the uniaxial compression was gained by tests. Meanwhile, calculation method of static and dynamic load was obtained with lateral strata’s constructional model established .The results shows that: process of roadway-side filling with gangue was simple and scientific basis was provided for the supporting design determination.关键词
