The drilling operation in the roof bolting process, especially in hard rock, generates excessive respirable coal and quartz dusts, which could expose the roof bolting operator to continued health risks. Previous research has shown that the amount of respirable dust produced is dependent on the main drilling parameters, specifically the drilling rotational and penetration rate. In this paper, a roof bolter drilling control process was proposed to reduce the generation of respirable dust. Based on the analysis of laboratory drilling test results, a rational drilling control process (adjusting rotational and penetration rates) to achieve the optimal drilling parameter for different rock types was proposed. In this process, the ratio between specific energy and rock uniaxial compressive strength was used as the index to determine the optimal operation point. The recommended drilling operation range for the rock type used in the experiment was provided, and the reduction in respirable dust generation was demonstrated. By following this control process, the drilling efficiency can be monitored in real time, so the system can stay in a relatively high-energy efficiency with less respirable dust production from the drilling source. This algorithm is targeted to be incorporated into the current roof bolter drilling control system for drilling automation so that a safe and productive drilling operation can be conducted in a healthy working environment.

顶板锚固过程中的钻孔操作，尤其是在坚硬的岩石中，会产生大量可吸入的煤和石英粉尘，这可能会使顶板锚固操作员面临持续的健康风险。先前的研究表明，产生的可吸入粉尘量取决于主要的钻探参数，特别是钻探旋转速度和穿透速度。本文提出了一种屋顶锚杆钻进控制方法，以减少可吸入粉尘的产生。在分析实验室钻探测试结果的基础上，提出了一种合理的钻探控制过程（调整旋转速率和穿透速率），以实现针对不同岩石类型的最佳钻探参数。在这个过程中 用比能与岩石单轴抗压强度之比作为确定最佳工作点的指标。提供了实验中使用的岩石类型的推荐钻孔操作范围，并证明了减少了可吸入粉尘的产生。通过遵循此控制过程，可以实时监控钻探效率，因此系统可以保持较高的能源效率，而钻探源产生的可吸入粉尘较少。该算法的目标是将其合并到当前的屋面锚杆钻探控制系统中，以实现钻探自动化，从而可以在健康的工作环境中进行安全而高效的钻探操作。并证明减少了可吸入粉尘的产生。通过遵循此控制过程，可以实时监控钻探效率，因此系统可以保持较高的能源效率，而钻探源产生的可吸入粉尘较少。该算法的目标是将其合并到当前的屋面锚杆钻进控制系统中，以实现钻进自动化，从而可以在健康的工作环境中进行安全高效的钻进操作。并证明减少了可吸入粉尘的产生。通过遵循此控制过程，可以实时监控钻探效率，因此系统可以保持较高的能源效率，而钻探源产生的可吸入粉尘较少。该算法的目标是将其合并到当前的屋面锚杆钻进控制系统中，以实现钻进自动化，从而可以在健康的工作环境中进行安全高效的钻进操作。
