Abstract: According to the status on no driing measuring means during the borehole constructon perod of the spiral drllig technicue,based on the analysis on the spiraldriing technique and the specialrequirements of the drlling measurement equipment.the paper systematcal studied the driing rack measuing method underground constiuction method and the drling rack caculaton method and completed set of the drling measurement equipment was researched and developed. in ofderto solve a poor borehole completed rate of the gas drainage boreholein the sof seam and the dificult cuttng discharging problem,an integrated wide blade nonmagnet c spiral diling rot was designe . The practices and application resuhts in the mining area showed that the rllig rack measuring technology and the equiment could meet the technical requrements of the spiral driling technique. n comparison with the conventional iling neasurement metiod,the driing track measuring teachnology and the equipment could improve the construction eficiency by 40% and could provide new technical acess to the gas control of sof seam
