注浆水泥代用材料在丁集矿井巷道充填加固中研究与应用

丁集煤矿煤层埋藏深,巷道地压大,显现快。为提高巷道的抗压性,巷道进行注水泥浆作为充填和加固材料,效果显著,但成本大。为降低成本,合理选用材料,使用多种材料进行试验。试验证明,黄石粉与水泥配比代替纯水泥作为注浆加固、充填材料,效果显著,工程费用降低。

DingJi coal mines buried deep tunnel pressure, quickly emerged. To enhance the resistance of the roadway and tunnel to carry out water and mud filled as a reinforcement material, the results are obvious, but the big cost. In order to reduce costs and a reasonable selection of material, the use of a variety of materials to test. The results showed that Yellowstone and cement powder in place of the ratio of pure cement grouting as a reinforcement, filling materials, a significant effect, lower the cost of the project.
