Drilling rig sticking, which poses great danger for operators in coal mine production, occurs frequently owing to various factors during the process of drilling in underground coal mines. To solve the sticking problem, the hydraulic power of the drilling rig, which has a significant influence on sticking, is studied. The relation between the torque provided by the hydraulic power unit and the torque required is determined. A model of the hydraulic system based on the multi-way valve applied in a typical drilling rig is built using the hydraulic component design of AMESim; then, the hydraulic system model is simulated under similar working condition with actual condition. Subsequently, a theoretical expression is deduced according to hydraulic and mechanical theorems, and a control method based on dynamic performance curves and relation expression (MDPRE) combining system simulation with theoretical expression is proposed. Finally, experiments are conducted 10 times/shifts to validate the MDPRE. The ultimate results show that the solution is viable and effective.
