Excavating method for ox-nose shaped roadway

Disclosed is an excavating method for an ox-nose shaped roadway. The excavating method includes steps of dividing a roadway to be excavated into a part I, a part II and a part III; laying out shock relieve vents respectively at equal intervals along the circumferential direction, close to the part III, of the part I and the part II; excavating an outer half range of the part I; adopting the same operation in excavating the outer half range of the part I to excavate an inner half range of the part I; removing waste residues produced from excavating the part I; adopting the same operation in excavating the outer half range and the inner half range of the part I to excavate the part II; removing waste residues produced from excavating the part II to form the ox-nose shaped roadway. Having obvious effects in preventing deformation of original rocks, improving construction efficiency, reducing construction cost, facilitating safety control and the like, the excavating method is popular and practical, easy to popularize, and has good social and economic benefits.
