在井下开采中,液压支柱是要求具有较高安全性和可靠性的一种构件。即要求它在活柱伸出的任何位置都具有较大的支撑力,以及当围岩移近量很大时能均衡地可缩。掩护式液压支架中液压支柱的两个重要参数是其伸缩范围和缸体直径。通过调节掩护梁和运输机之间立柱高度来改变工作面通道面积。对于掩护式支架液压立柱的发展进行长远的考虑,因而得出下列主导思想,这种思想可以通过解析计算得到征明。
In underground mining, hydraulic props are components requiring high safety and reliability. That is, it requires greater support at any position where the column is extended and when the surrounding rock is moving in close proximity, it can be deflected. Two important parameters of the hydraulic props in the shield type hydraulic support are their telescopic range and cylinder diameter. Change the channel area of the face by adjusting the column height between the shield beam and the transport plane. For the long-term consideration of the development of the shield type hydraulic column, the following dominant ideology is derived, which can be obtained through analytic calculation.
