E型推移与磨架装置在煤矿液压支架拆除中的应用研究

为了保证煤矿液压支架安全高效快速拆除，对陈四楼煤矿综采工作面液压支架回撤过程中的E型推移与磨架装置进行了研究。分析了新型E型推移与磨架装置的基本参数、机构原理、实施过程等性能特点，并重点研究了推移框架在受较大冲击载荷时的防夹斜问题。结果表明，新型E型推移与磨架装置可实现“交叉、迈步”直线自移功能，同时指出了此装置技术在现代化矿井综采工作面液压支架拆除回撤应用中的重要性。

Application of E-type Passage and Grinding Device in Hydraulic Support Removing of Coal Mine

To ensure the smooth and high efficient removing of hydraulic support in coal mine，the new E-type frame and grinding apparatus was studied during hydraulic support removing on fully-mechanized coal mining face in Chensilou Coal Mine. Analysed the basic parameters，features principle mechanism，the implementation process of the apparatus，the anti-oblique problems of supports were analysed when they are encountering large impact load. Results have shown that，the E-type frame and grinding apparatus can realize the function of "cross and stride". In the end，the importance of this apparatus was proposed in the application of hydraulic support removing on fully-mechanized coal mining face in modern coal mine.
