摘　　要：露天采矿随钻测量技术研究目前尚处于初期阶段,研发随钻参数测量系统是实现随钻测量技术服务于采矿工程行业的首要任务。基于TAIYE-390-Ⅱ潜孔钻机工作原理,确定了随钻参数,提出了一套通用的测量方法,并研发了测量装置。装置主要由数据采集系统、数据转换系统和数据处理系统组成,可实现对钻进时间、钻进深度、钻进速度、钻杆轴压、回转力矩、回转速度、冲击风压和冲击风量等参数的实时准确测量、采集、计算、存储、显示和远程传输。结合某石灰岩矿钻孔数据,提出了一种反映岩性变化的数据整合方法,并借助钻孔成像试验分析了随钻测量技术在岩体结构面识别中的可行性。结果表明钻进速度和回转力矩对岩体结构响应最为灵敏,冲击风量和冲击风压在钻凿含孔洞的破碎岩体时表现突出,而钻杆轴压和回转速度在岩体结构识别中作用较小。研究成果在潜孔钻机随钻测量系统研发和随钻岩性识别等方面具有重要的理论意义和应用价值。The researches on the measurement while drilling(MWD)technology in the field of open-pit mining are still in the early stage,and the development of MWD systems is the primary task to realize the application of MWD technology in the mining engineering industry.Based on the working principles of the TAIYE-390-Ⅱhydraulic DTH drilling rig,the MWD parameters and a universal measurement method are respectively determined,and the corresponding measurement devices are developed.The devices mainly include a data acquisition system,a data conversion system,and a data processing system,which can realize the real-time and accurate measurement,acquisition,calculation,storage,display and remote transmission of parameters such as drilling time,depth,penetration rate,axial force,rotation torque,rotation speed,percussive air pressure and air quantity.With the MWD data from a limestone mine,a data integration method that can reflect lithological variations is proposed,and the feasibility of MWD in the structural identification of rock mass is analyzed through the borehole imaging experiments.The results indicate that the penetration rate and rotation torque exhibit the highest sensitivity to rock mass structures.The air quantity and air pressure are more sensitive only when drilling fragmented rock masses with cavities,while the axial force and rotation speed have limited influences on the structural identification of rock mass.The research findings are of important theoretical significance and practical value in the development of MWD systems for DTH drilling rigs and lithological identification.
