摘　　要：根据煤矿用钻杆在使用过程中频繁出现拆卸困难的问题,从理论和试验分析了煤矿用钻杆圆锥螺纹紧密距对钻杆拆卸的影响,推导了钻杆紧密距的相关计算公式,并通过试验分析,得出一个最优的紧密距范围。In view of frequent difficulty in disassembly of the drill pipe used in collieries during service course, the influences of the stand-off thread of the taper screw of the drill pipe used in colliery on the disassembly of the drill pipe by theory and tests. In addition, the formulae of calculating the stand-off thread of the taper screw were deduced, and optimal range of the stand-offthread was obtained by test and analysis.
