| 摘 要： | 铁法矿务局晓南矿西三４０６工作面所用经改造的Ｇ３２０掩护式支架常被压坏压死，根据现有的矿压观测条件采用０－６０ＭＰａ压力表跟班测试Ｐｏ，Ｐｔ，Ｐｍ值，并对所得大量数据进行了详细分析，证明本套支架不适应晓南矿西三四层顶板管理的需要，并根据数据分析为本层煤液压支架工作阻力的确定提供了依据。

| Abstract: | The hydraulic prop that had been reformed before didn't work properly because of the roof pressure in W3406 coalface of Xiaonan Mine,Tiefa Mining Bureau.In available condition,the value of P0, Pt, Pm were assured with the 0-60 Mpa pressure barometer.The detailed analysis of many measured data showed that this kind of prop is not suitable for the third and the forth coalseam in Xiaonan Mine.The analysis also provided the basis to determine the hydraulic prop resistance. |
