增强井下混凝土强度的可行性研究

Research on Feasibility of Enhance the Concrete Strength Under-mine

现在煤矿企业井下矿务工程大多是混凝土工程。这不仅为矿井的安全、高效生产奠定了基础，同时也为提高矿井的质量标准化起到了不可替代的作用。但由于混凝土的井下施工，受到例如顶板淋水、井下潮湿、底鼓等因素的不利影响，采用真空吸水技术和改变混凝土原料配比，增强混凝土强度和防渗能力，保证了工程质量，取得了良好的经济效果。

Concrete is widely used on under-mine project. It＇s not only for safe and efficient production, but also takes part in improving quality standardization of the mine. Affected by bottom swelling and wet under-mine, people always take some solutions such as vacuum suction and change the material＇ s formulation to enhance the concrete strength and ability of anti-infiltrate. This way ensures the project quality and has achieved good economic results.
