产品介绍：
</p>
<p class="MsoNormal">
<span>摩擦支柱利用摩擦力产生支护力的可缩性支柱。它与金属铰接顶梁配合构成单体支架</span>,用于维护工作面控顶区顶板。摩擦支柱适用于底板较硬,无明显冲击地压,煤层倾角小于25°的缓倾斜薄及中厚煤层工作面,采取一定的安全措施,也可用于25°～35°的采煤工作面。
</p>
<p class="MsoNormal">
<span>摩擦支柱由柱锁、活柱和柱筒三部分组成。</span> <br>
<span>摩擦支柱具有初工作阻力高和可缩量大等特点</span>,支柱设后能很快达到初工作阻力,及早发挥对顶板的支撑作用,而且还能用于顶板下沉量较大,有周期性来压工作面。
