大倾角综放工作面液压支架优化设计技术研究
|
摘要
大倾角综放工作面液压支架的设计及技术研究,由于其工作面矿压显现和围岩破断活动的复杂性而进展缓慢,较少见到国外主要产煤国家此方面的专门文献。我国目前的液压支架研究、试验与使用水平处于国际该领域的前沿。分析表明,大倾角综放工作面安全、高效开采的关键是对围岩的有效控制,而围岩控制的难点在于支架围岩系统的稳定性,液压支架作为支架围岩系统中的人为可控因素,对其稳定性起着关键性的作用。
本课题对大倾角综放工作面液压支架的优化设计技术进行了研究。通过研究大倾角综放工作面支架与围岩相互作用关系与作用机理,提出了影响支架稳定性的关键因素——支架工作阻力及其分析计算方法。构建并分析了支架围岩关系模型和工作面支架组整体分析模型,验证了支架与围岩关系理论研究的正确性。设计了ZF5600/16.5/26型大倾角综放工作面液压支架,总结了支架的多种不同受力情况,并对支架模型进行了ANSYS结构有限元分析,验证了该型支架可靠性,阐述了不同载荷情况下支架的优化设计方法。同时研究了大倾角液压支架稳定性,构建并分析了支架的防滑防倒模型,使支架的稳定性防护结构最大程度地满足实际要求。在此基础上提出了适应于大倾角综放工作面的液压支架优化设计技术。
本课题的研究丰富和发展了大倾角综放工作面液压支架设计理论和方法,为实现支架的优化设计提供了一定的理论和方法借鉴。
The hydraulic support design technology of the fully-mechanized top coal caving face with heavy dip angle has making a slow progress because of the complexity of strata behaviors and rock fracture. There is less special literature in the main producing coal country abroad, the current research and using level of our country is in the lead level in the world. Analysis and research show that the key of the secure and efficient coal mining in the fully-mechanized top coal caving face with heavy dip angle is effective control measures for surrounding rock. But the stability of support and surrounding rock system is the difficulty for surrounding rock control. Hydraulic support is the key active factor of the surrounding rock control. The effect of the hydraulic support is a decisive function, so it is very important to optimize design techniques and methods of hydraulic support according to the interaction relationship between the hydraulic support and the surrounding rock.
The dissertation studied the optimization design technology of hydraulic support in the fully-mechanized top coal caving face with heavy dip angle based on the interaction relationship between support and surrounding rock. The interaction relationship and mechanism between support and surrounding rock has been studied, the key factor is proposed - Determination of working resistance of support under different top coal conditions which influences the stability of hydraulic support. The analysis of the interaction relationship model between support and rock has been realized. The theory of relationship between support and surrounding rock was verified. The ZF5600/16.5/26 type hydraulic support in the fully-mechanized top coal caving face with heavy dip angle was designed, the different force conditions of hydraulic support has been summarized. The model finite element analysis was realized by using the software ANSYS. The structural reliability of support was verified. The optimum design methods of hydraulic support was discussed under the different load condition. The anti-slipping and anti-falling stability of the hydraulic support in the heavy dip angle caving face has been studied. The analysis of anti-slipping and anti-falling stability model has been realized. So the support structure design meets the need of actual requirements for controlling the rock effectively. The optimization design technology of hydraulic support in the fully-mechanized top coal caving face with heavy dip angle under complicated conditions has been put forward.
The design theory and methods of hydraulic support in the fully-mechanized top coal caving face with heavy dip angle were enriched and developed through the study. The dissertation provided the theory and method reference for the optimum design of hydraulic support.
