摘要随着工业的出现，大型机械也随之出现，大型机械也必定消耗大量的能源，因此与之相应的能源产业也在不断成长，煤作为一种最原始的能源被人类大量开采。我国是最早发现并使用煤炭能源的国家之一，在这一领域已经探索了数个世纪。在中华人民共和国成立以后,我国政府大力发展重工业，开设了数量众多的新矿井,改建了许多原有的旧矿井，仅仅几十年的时间，我国煤炭产量已经达到了一个很高的水平。虽然煤矿资源用途广泛经济效益巨大。但是在开采煤层矿层的时候往往会发生重大的灾害！埋在地底的岩石经过水的侵蚀作用之后，岩石内部的孔隙度和渗透量会随时间的改变而变化，岩石常常发生水流形态的转变，由此引发突水灾害。在发生陷落柱突水之前，岩石经历了长时间的质量流失，所以通过加速渗透试验来模拟陷落柱质量迁移和流失是科学的选择。

    经过理论的推导，我们研制了一套可以模拟地底破碎岩石受水侵蚀的渗透试验系统，这套系统由数个独立的系统构成，实现两种方式渗透试验可以自由切换73899

Design of Seepage test Bed for Fractured Rock mass

Abstract   With the emergence of the industrial revolution, large machinery has emerged, large machinery also will consume a lot of energy, so energy industry and the corresponding also growing in coal as a kind of the most primitive energy is a large number of human exploitation。 China was one of the earliest countries to discover and use coal energy, and it has been explored for several centuries in this field。 After the founding of the people's Republic of China, the Chinese government vigorously develop heavy industry, opened a large number of new mine, rebuilt many of the old mine, just a few years time, China's coal production has reached a very high level。 Although the use of coal resources in a wide range of economic benefits。 But when the coal seam often occur in major disasters! The porosity and permeability of the rock will change with time, and the change of the water flow pattern will occur when the rock is buried in the ground。 Before the occurrence of water inrush from collapse column, the rocks experienced a long time of quality loss, so the accelerated penetration test to simulate the collapse column mass transfer and loss is scientific choice。

    Through theoretical derivation, we have developed a can simulate the bottom rock breaking by water erosion of penetrant testing system, this system consists of a number of independent system, two ways to achieve penetration test can freely switch
