| Abstract: | By means of laboratory test,theoretical analysis and calculation,numerical simulation and other methods,the combined support method of bolt and anchor cable is designed to support the 1501 transportation channel of Longdingshan Coal Mine,and the main parameters are determined.After the field application,the displacement monitoring of surrounding rock is carried out.The maximum subsidence of the roof of the 1501 transportation channel is 16.5mm,and the maximum displacement of the two sides is 15mm,which achieved good supporting effect. |
