| Abstract: | Because of the large diameter of mine feeding well, grading reaming is adopted. The wear resistant pipe of feeding well has high stiffness and heavy weight, which has high requirements on borehole verticality, lifting equipments and appliances, serious safety or quality accidents often occur in the construction. Based on a series of engineering practices, with the case of a feeding well in Inner Mongolia, this paper summarizes the drilling completion construction technology of feeding well and the key points of control. |
