Design and application of combined supporting of beam metal net in fracture zone roadway of big cross section of deep well
LU Chun-yu
Abstract：-1010 m mining area of Jiahe coal mine of XuZhou mining area after cutting,mine pressure ap-pear,two displacement of floor heave of roadway is bigger,which affects the normal use of roadway. By beam metal net and shotcrete reinforcement technology of surrounding rock,the mechanical properties of surrounding rock is changed,which gets good supporting effecf for the disrepair roadway,and is of certain reference value to the roadway deformation control and later maintenance.
