Experimental Research On High Temperature In Deep Roadway Thermal Resistance Properties Of Concrete

Deep well mining is the trend of underground coal mining in China, the high temperature environment of the deep mine brings a very negative impact on mine production. To improve the high temperature environment of the deep mine is a major technical problem that needs to be solved urgently in the current coal mine production and construction.High-temperature thermal paper appears safe for excavation and Huainan coal mine roadway in deep areas of injury problems, according to the mechanism of heat transfer analysis of deep roadway in this paper uses a new type of insulation material to inhibit high temperature dangerous roadway. By ordinary concrete material is replaced by a new type of insulation material and then the ratio of theoretical calculations, and then measured the thermal conductivity of the new material, the test instead of using a certain amount of ceramic stones, glass beads instead of the sand with a certain amount of to achieve thermal insulation effect, by comparing experimental results obtained both physical mechanical properties of concrete in general, but also has insulation performance, energy saving, green, environmental protection, high efficiency ecological materials. Paper orthogonal experimental method to ceramic particle size, the amount of ceramic, the type of glass beads, the beads breaking amount, the amount of fly ash, sand, etc., as the amount of Factor using range analysis method, the extent the influence of various physical and mechanical properties and thermal properties of concrete research, by screening efficacy coefficient method to elect the best basis insulated concrete mix. According to the actual construction process requirements and economic analysis, deep thermal heat resistant concrete roadway optimum proportion.New insulation materials made of paper is an active heating technology, complement to traditional air cooling and artificial enlargement of cooling technology for deep mine roadway to provide a safe and reliable basis, has a more significant economic and social benefit.
