-
Abstract
Combining the bolting practice in drifting along the goaf at Xiezhuang Coal Mine,a new design method by field observation is introduced.The primary design is put forward by estimation of geological mechanic and industrial test,then according to the information from field observation,the design is revised.Industrial test is conducted again to verify,and the perfect design is formed at last.
