Abstract: In order to solve the problem that ground freezing method for inclined shaft was the vertical shaft hole freezing technology in Western China,and adopt to th e requirements of the inclined axis freezing process,it was necessary to study the key equipment for directional drilling in freezing method for inclined shaft. The drilling rig of small inclination angle nearly horizontal surface and installation device of freezing tub had been developed. We had finished the field test of directional technology by wir eless measure while drilling and the laboratory test of magnetic guide technology. The inclinometer accuracy could meet the requirements. The research results were poten tial ways to solve the problem of inclined holes dillig,freezing tub installation and drilling accuracy.
