Abstract：As the drilling cost of the external drilling team was relatively high due to weak stratum, long distance material supply, quick corrosion of drilling pipe and tools, water shortage for production and living and other factors in Xinjiang Zhundong Coalfield. This paper successfully introduced the ABC classification for warehouse management to the drilling project. According to the method, primary influencing factors for drilling cost included diesel oil, slurry material, drilling pipe and tools, and water for production and living. The secondary factors was accessories and the general factors were others, drill bits and tools. According to the degree of importance, the main factors management were specially strengthened and cost management measures were formulated in detail. The secondary factor management was strengthened by the measure of ration supply and turning old for new. The general factors management was properly strengthened by carrying out the daily management system strictly. Through these measures, the mine drilling cost in Zhundong Coalfield Kulankazgan was reduced by 21. 59%.
