【摘要】 在我国煤炭行业，采煤与掘进之间的关系一直处于紧张状态，并且绝大多数煤矿的巷道支护还在采用人工方式。针对巷道支护作业中的铺设锚网环节设计了一种与现有的掘进机配套的门式支架进行配合的自动铺网装置，旨在取代人工作业，以提高掘进效率和增强巷道顶板的安全性。通过对自动铺网装置的支护工况展开数值模拟，对其进行静应力分析，重点研究不带网与带网2种工况下的力学行为与支护效果。通过对比2种工况的模拟结果，得出自动铺网装置对支护性能的显著影响，为自动铺网装置的结构优化与工况适应性设计提供了理论依据。更多还原

【Abstract】 In China′ s coal industry, the relationship between coal mining and excavation has always been tense, and the majority of coal mines still use manual methods for roadway support. Designed an automatic mesh laying device for the anchor mesh laying process in roadway support operations, which is matched with the existing portal support of the roadheader, so as to replace manual operations,improve excavation efficiency, and enhance the safety of the roadway roof. Numerical simulations of the support conditions of the automatic mesh laying device was conducted to perform static stress analysis,and focused on the mechanical behavior and support effect under two working conditions: without mesh and with mesh. By comparing the simulation results of two working conditions, it was concluded that the automatic mesh laying device has a significant impact on the support performance, providing a theoretical basis for the structural optimization and adaptability design of the automatic mesh laying device.更多还原
