چکیده انگلیسی
In order to study stability control methods for a deep gate group under complex stresses, we conducted field investigations and analyses of reasons for damage in the Xuzhou mining district. Three reasons are proposed: deep high stress, improper roadway layout and support technology. The stability control countermeasures of the gate group consist of an intensive design technology and responding bolt-mesh-anchor truss support technology. Our research method has been applied at the −1000 m level gate group in Qishan Coal Mine. Suitable countermeasures have been tested by field monitoring.
