考虑到综掘巷道液压迈步式超前支护装备的工作原理，以及超前支护在过渡阶段中的降架过程的实际工作特点，以减小超前支护装备降架过程对顶板扰动影响为控制目标，基于体积平均释放规律，研究比例节流阀阀芯位移与降架过程时间的关系，从而确定适合超前支护降架过程的阀芯位移控制曲线。为验证控制方法的性能，将其与以直线、指数、对数曲线控制阀芯开度的方法相比较，对其作用效果进行理论分析和试验研究。分析与实验结果表明，基于体积平均释放规律曲线的降架控制方法能够将超前支护装备降架过程的支撑力平稳地卸载，比较其他控制方法，在相同降架时间内控制效果最优，对顶板扰动影响最小。该种控制方法为综掘巷道液压迈步式超前支护装备的研发及控制策略的研究提供了理论依据。

Considering the working principle of hydraulic‐walking advanced support equipment , and advanced support during the transition phase in the falling process of actual work ,in order to reduce the disturbance w hen forepoling equipment falling on roof ,based on volume average re‐lease rule ,the relationship between displacement of proportional throttle and time of frame de‐scending process w as studied ,so as to determine the suitable spool displacement control curve of advanced supported frame descending process .In order to verify the performance of the control methods ,it was compared with the straight line ,exponential and logarithm curve control meth‐ods ,and made theoretical analysis and experimental study on its effect .Analysis and experimen‐tal results showed that ,the control method which was based on volume average release rule could effectively and smoothly unload the support force during the advanced supported frame descend‐ing process ,achieve the best control effect during the same period of decending ,with minimal im‐pact on the roof disturbance ,compared with other control methods .This control method provid‐ed the theoretical basis for advanced supporting equipments'development and its control strategy research .
