WANG Jin-hai
Abstract：How to improve a breakthrough precision and quality of an underground mine roadway is al‐ways an issue concerned by the survey workers. The paper briefly introduced the breakthrough survey plan as well as the breakthrough error prediction and the precision analysis condition of the break ‐through measured information of No.3 horizontal transportation roadway in No.6 Mine of Hebi Coal Industry Company.Due the breakthrough survey plan was rational and feasible ,a high precision and high efficient breakthrough of the mine roadway was realized and the breakthrough precision was fully met with the regulation requirements and reached the estimated effect.
