| Abstract: | The longer the strike of the working face and the longer the breakthrough distance are,the greater the error accumulation is.Taking the 8602 working face of Yungang Mine as an example,this paper puts forward the technical measures to reduce the error of through measurement.The practice results show that the deviation of through roadway meets the requirements,and the error of through closure measurement meets the design requirements. |
