Abstract：An adv anced deep-hole blast tech nique w as adopted in the fi rst-stag e engineering w o rk o f la nd lev elling for const ructing a new chemical facto ry at Ning bo. Acco rding to the specialities o f this engineering w ork, based on the testing resea rch in si tu, the economic reasonable heig ht of the bench cut and the sui table resistant depth o f the subsoil were selected. Otherwise, acco rding to the topog raphic and geologic conditions, bet ter ideal di rving di rection o f blast and o ther technical measures w ere ado pted. Thus, the quali ty of blasting w as improved, the si ze of f ractured block w as in accorda nce w ith the desig n requi rement , harmful effect s of blast w ere decreased, and the o n-time accomplishment of the engineering pro ject w as g ua ra nteed.
