Research on Supporting Techniques of Deep and Large-Section Coal Roadway Blow Thin Fractured Bedrocks
This paper is basis on previous studies, taking The main haulage roadway of the western district of Zhaogu No.1 mine ,which belongs to Jiaomei group, as the background of study. On the basis of understanding the mechanical properties and engineering characteristics of soft rock, proposing the stability control mechanism and supporting scheme design countermeasure of fractured soft rock roadway. Numerical analysis was made to the stability of roadway surroundings used the FLAC-3D finite element analysis software, and a set of reasonable supporting technology schemes and parameters were proposed.
