Abstract:
150109 haulageway surrounding rock is very soft, easy spalling coal wall, poor forming roadway, broken roof, which brings great difficulty to roof control. For this purpose, the geological mechanics test and drilling peep approach are used to understand the basic form of the roof; the dynamic information support design method is used to research and identified the roadway support parameter and mode, which are carried out in the field application. According to the station monitoring datum, the proprosed high pre-stress anchored bolt and anchored rope combined supporting in this paper provides effective supporting approach for soft and cracked coal roadway.
