摘要:
基于对上保护层的开采及其渗透性影响因素的分析,自行研制了上保护层开采时被保护层渗透性测试相似模拟实验台。本实验台解决了对两煤层处于不同间距及不同采高条件下的开采过程中,被保护层渗透性变化的问题。实验结果表明,被保护层随工作面的推进,瓦斯渗流速度的变化趋势,经历了由原始渗透性先降低、后升高、再降低、再升高、最后保持不变的过程。
Abstract:
By the analysis of the effective factors on upper protective layer mining and its permeability, a simulation experimental platform on upper protective layer mining was developed.The experimental platform solved the question of testing the permeability when two coal seams in different conditions of gaps and mining height. The experiment results showed that the change trend of seepage velocity with the face advancing decreased first, then increased, later, decreased, increased again and finally kept unchanged.
