Extension characteristics of the “Butterfly-shaped” plastic zone and stability control of deep mining roadway in Xingdong mine
The distribution of plastic zone of surrounding rock in deep mining roadway is the key to control the stability of surrounding rock. Taking the deep mining roadway of Xingdong Mine as the research background, according to the "butterfly-shaped" plastic zone theory and combining with numeri...

| description | The distribution of plastic zone of surrounding rock in deep mining roadway is the key to control the stability of surrounding rock. Taking the deep mining roadway of Xingdong Mine as the research background, according to the "butterfly-shaped" plastic zone theory and combining with numerical simulation analysis the plastic zone of the surrounding rock in 2225 transport roadway of Xingdong mine is found to have a characteristics of "butterfly-shaped" expansion.By studying the influence of different support resistance on plastic zone of surrounding rock under deep conditions,a method of stability control of surrounding rock under the deep condition is proposed to provide appropriate support resistance to reduce the tensile failure of surrounding rock and maintain the stability of fractured rock mass in the plastic zone of roadway surrounding rock.The support scheme for the "Butterfly-shaped" plastic zone of 2225 transport roadway surrounding rock in Xingdong mine is put forward,which can provide a reference for the stability control of the deep mining roadway. |
