巷道围岩破坏的地应力特征与数值模拟
Numerical simulation and properties of in-situ stress field on roadway surrounding rock failure
摘要
Abstract
This paper is concerned with the deformation and destruction of roadway in Xinli Coal Mine during mining.The research includes selecting three typical in-situ stress measurement points of-600 west five area rock haulage roadway and west four auxiliary roadway;measuring ground stress using air core inclusion ground stress measurement method;identifying the distribution law behind in-situ stress field;and thereby analyzing -600 west five area rock haulage roadway in mine field using FLAC3D soft-ware.Results indicate that the maximum principal stress is 2.01,2.09,2.08 respectively times the verti-cal stress;the stress field in the mine field is dominated by NW-SE horizontal tectonic stress;the greater deformation of the two sides and floor heave is due to the influence of horizontal tectonic stress field, leav-ing arch shoulder and bottom corner greatly deformed and seriously damaged.There is a basic agreement between the result and the actual situation in the field.It may provide an important reference for roadway layout and support parameter design in mine fields.关键词
