- W2348045314 abstract "Analogue simulation is an important method for researching water burst mechanism of mine and high water-resistance property of fluid-solid coupling simulation material is the key. For mining face with roof water burst danger in Shigetai Colliery,matching experiment of fluid-solid coupling analogue simulation material was made. Applying medium-coarse sand,plaster,calcium carbonate,paraffin and vaseline to stirring evenly with some proportion and simulating actual rock strata( medium sandstone,sandy mudstone,siltstone,coal-seam,fine sandstone),permeability ratio of every group specimen was tested and permeability coefficient was calculated. According to classification criterion of permeability parameters,using the permeability coefficient which was smaller than 10-5cm / s as indication value of high water-resistance property,48 groups experiment was finished. Results showed that with paraffin content increasing,specimen's strength rose and flexibility reduced,when paraffin content was larger than 8%,water-resistance property was excellent,on the basis of this,8% of vaseline mixture could reduce specimen's elastic module and improve deformation ability. Rational mixture of vaseline and paraffin could make fluid-solid coupling material with high water-resistance property." @default.
