The variation rule of TBM tunneling parameters in deep composite strata and the recognition method of boreability grade

Abstract To evaluate the energy efficiency of tunneling with an open full-section road header constructed in deep coal composite strata, this study relies on the development project of the 1# backdraft tunnel in the western area of a mine located in Binchang, Shaanxi Province. The analysis is based...
