通过设定恒定活塞下压力,测试不同Talbol幂指数n级配下的破碎砂岩受压位移,换算破碎砂岩的密实度,采用轴向力连续加载方式,研究破碎砂岩的渗流规律与Talbol幂指数n的关系,为预防突水、煤与瓦斯突出等灾害提供指导。
By setting the pressure of constant piston, test compression displacement of different Talbol exponent n graded crushed sandstone, conversions crushing density of sandstone, adopting continuous loading of axial force, to study the seepage law of fractured sandstone and Talbol power exponent n. For preventing water inrush, such as coal and gas outburst disaster has important engineering significance.
