     The paper analyzes the formation characteristics in Ashele mining area of Xinjiang and sums up the deep drilling experiences in hole structure and drilling tool grading, drilling equipment selection, drilling technology, wall protection and shut-off technology as well as drilling deviation control technology in Ashele area. According to the complicated broken formations, hole circulation loss and serious deflection-promoting in strata, the relative technical measures are presented.
