Abstract
The wellbore rupture has a significant influence on the mine safety production.In view of the wellbore rupture and water seepage phenomena that occurred in the auxiliary shaft of Chenmanzhuang Mine at depths of 126 m and 262 m,it is analyzed and found that the cause of the rupture is that the vertical additional force exceeded the well wall bearing capacity.Due to the lack of inter wall grouting after the wellbore is put into use,it is decided to adopt a governance scheme that combines inter wall grouting with steel plate cylinder reinforcement in ruptured sections:6 holes per row,spaced 30 m apart,with a total of 186 grouting holes constructed,and 9 water blocking holes in the-162 m damaged section;To meet the safety gap of the damaged section,the reinforcement method selects thick steel plates with high-strength filling materials,broken gangue excavation and steel plate grooves treatment are conducted on the well wall at the cage angle.The engineering practice shows that after grouting,the water inflow of the wellbore is reduced from 7 m3/h to below 2 m3/h,effectively solving the problems of wellbore rupture and water leakage during freezing method construction,providing technical reference and practical basis for the governance of wellbore rupture under similar conditions.关键词
