基于煤矿井下施工钻孔间距大、钻机需频繁长距离搬迁的实际需求，以及遥控操控功能需要，采用胶轮式定向钻机整体紧凑布局及各单元模块化设计的研究思路，解决独立行走的胶轮底盘、多动力配套输出单元、液压系统及电控系统等关键技术开发难题，整机加工、装调后在国家安全生产检测检验中心钻机性能试验台上模拟负载测试。试验表明钻机的各项功能参数均达到设计要求。研制的ZDY3500JDK型煤矿用胶轮式定向钻机，满足井下长距离自主搬迁需求，极大提高了矿井生产运输效率，为具备无轨胶轮化运输的大中型矿井钻孔施工作业提供了可靠的装备保障。

Based on the actual needs of large drilling spacing, and frequent long-distance relocation of drilling rigs in coal mine underground construction, as well as the need for remote control function, a research idea of compact layout and modular design of each unit of rubber wheel directional drilling rig was adopted to solve key technical development problems, such as independent walking rubber wheel chassis, multi power output units, hydraulic system, and electrical control system. After whole machine was processed and assembled, load testing was simulated on the drilling performance test bench of the National Safety Production Inspection Center. The experiment shows that all functional parameters of the drilling rig meet the design requirements. The ZDY3500JDK rubber tyre directional drilling rig developed for coal mine meets demand for long-distance autonomous relocation underground, greatly improving the production and transportation efficiency of mine, and providing reliable equipment support for drilling construction operations in large and medium-sized mines with trackless rubber tyre transportation.
