摘要

    摘要
  • 摘要: 为研制用于动压巷道支护技术相似模拟研究的试验装置,从采动压力出发分析归纳了采动的静压效应和动压效应,以此为设计思想,设计制造了新型的动压巷道支护相似模拟试验装置,给出了相应试验过程的设计,并进行了测试试验。研究表明：具有内、外框架嵌套式结构的新型试验装置可通过静载油缸模拟超前支承压力及侧向支承压力,并通过动载油缸模拟由采区顶板断裂、垮落等因素产生的振动荷载。测试结果表明新型装置可实现静、动荷载的同时加载,互不干扰;新型试验装置模拟的巷道模型破坏规律符合巷道破坏的一般规律,试验结果真实可靠。
    Abstract: For developing similar simulation equipment for roadway support subjected to dynamic pressure, the dynamic and static pressure effects related to mining are analyzed and summarized, which becomes the design idea for manufacturing the new similar simulation equipment to study the support technology of dynamic pressure roadway. Then the design of test processes is given, and the relevant experiments are performed. The results show that the inner-frame and outer-frame are the designed nested structure in the new equipment. The pressures on lead abutment and side abutment can be simulated by using the static load cylinder, and the vibration caused by mining such as roof breaking and roof caving can be simulated by using the vibrating cylinder. The new equipment makes reliable static and dynamic loads and is applied synchronously without interference. The failure laws of the roadway in the tests accord with the general ones of roadway damage, and the test results are reliable.
