为研究综掘巷道超前支护装备与巷道围岩耦合动力问题,基于薄板理论的顶板动力学模型,建立巷道顶板力学模型。简化超前支护装备,通过各部件的运动微分方程建立整机动力学模型;最后建立考虑多点支护条件下的超前支护-顶板体系耦合动力学模型。用多体系统动力学仿真软件Recur Dyn研究多种工况下耦合动力模型的动态响应过程。结果表明,在支护的压力冲击、振动以及综掘截割扰动等因素影响下,侧帮和顶板位移变形较剧烈。在有效支撑区段,变形小于未支护顶板的位移最大值;非有效支撑区段的位移极值小于未支护顶板的位移极值,表明超前支护对顶板变形有一定的控制作用。 In order to study the coupling motive force between advance supporting equipment and surrounding rock of fully mechanized mining roadway, the mechanics model of roadway roof is established based on the dynamic model of roof. The advanced support equipment is simplified, and the dynamic model of the complete machine is established through the differential equations of motion of each component. Finally, the coupled dynamic model of the advanced support-roof system considering multi-point support is established. The multi-body system dynamics simulation software Recur Dyn is used to study the dynamic response of coupled dynamic model under various working conditions. The results show that under the influence of pressure impact and vibration of support, and the perturbation of fully excavated cutting, the displacement of the side bog and roof is more severe. In the effective support section, the deformation is less than the maximum displacement of the unsupported roof. The displacement extremum of the unsupported support section is smaller than that of the unsupported roof, which shows that the advance support has a certain control effect on roof deformation.
