摘要
通过建立牙轮钻机单位钻孔深度成本模型，对钻孔的经济性进行了分析，合理地选择钻孔过程中的物压力和钻具的回转速度两个重要参数，可使钻孔成本降低，提高经济效益，同时又减轻了工人的劳动强度。
Establishing a cost model of drill hole, an economical analysis of drill hole is carried out It is enable to reduce cost of drill hole and to increase benefit by means of appropriately optimizing two important parameters at drilling process that are axial load and rota tional speed of drill bit .
