Abstract
In view of the problems caused by the current solid pipe technology of large diameter drilling,such as non-dense pipe and hole behind the pipe wall,the drainage pipe was installed and fixed through the developed check valve during the construction of drainage drilling in a mine,which solved the problems of non-dense pipe and more residue after the solid pipe.关键词
