摘　　要：为研究松软煤层螺旋钻杆对输煤效率的影响规律,以螺旋钻杆近水平钻孔应用为例,通过分析螺旋排渣机理,确定了影响排粉效率的4个参数,利用MATLAB优化工具箱对螺旋钻杆参数进行优化。在此基础上,采用EDEM软件对输煤过程进行了仿真分析。针对煤粒沿钻具轴向移动速度和质量流率2个指标对钻杆排粉效率进行了评价。In order to study the effect of spiral drill pipe on the conveying efficiency in the soft coal seam, the application of horizontal drilling was used as an example, the four parameters were determined by analyzing the slagging mechanism, subsequently the MATLAB optimization toolbox was applied to optimize the parameters of spiral drill pipe. Based on the results of the optimization, furthermore the conveying process was simulated and analyzed by EDEM, and the conveying efficiency was evaluated by axial velocity and mass flow rate.
