Based on wide-angle inclined shaft driving light blasting molding low quality in construction process, through construction analysis of the wellbore at 400 m, a series of countermeasures were settled to solve low quality of drilling hole, inaccurate lining and diameter-gauge without in accordance with wheel size drawing, unreasonable perimeter hole settlement and perimeter hole explosive load, the results showed that the technology could save a large number of construction materials, reduce the cost; The improvement of explosive forming light quality saved the manual work of roadway forming and blasting.
