摘要: 针对综放工作面液压支架回撤速度慢、转向过程液压支架底板下陷和易侧倾倒架等控制难题,综合采用现场调研、数值模拟和理论分析方法,开发了综放工作面液压支架安全回撤平台,分析了该回撤平台的主要结构和运行流程,模拟研究了液压支架和回撤平台作用过程中的应力和位移特征,并在水峪煤业典型综放面进行了现场工业性试验,综合应用效果良好,对类似综放面液压支架安全回撤提供一定参考。

Abstract: Aiming at control challenges such as slow retraction speed of hydraulic supports in fully-mechanized top-coal caving working face, sinking of hydraulic support base plate during steering process, and easy tilting frame, the comprehensive methods including on-site investigation, numerical simulation, and theoretical analysis methods were adopted to study the safety retraction platform of hydraulic supports in fully-mechanized top-coal caving (FMTC) working face. The main structure and operating process of the retraction platform were analyzed, and the stress and displacement characteristics during the interaction process between hydraulic supports and retraction platform were simulated and studied. Field industrial tests were conducted on a typical FMTC working face in Shuiyu coal mine, and the application effect was good, providing certain reference for the safe retraction of hydraulic supports in similar FMTC working face.
