凝胶液具有增加采空区空气阻力,增加空气、煤和岩石中的含水量,能长时间降低煤对氧的吸收作用,是防止煤自燃最有效的方法。 凝胶液由水玻璃、硫酸铵和92～95％的水组成。这些混合料随着比例和浓度的调整,固化时间可以从几秒钟到一个月或更长的时间,形成稳定的凝胶体。凝胶液有近似水的粘性,它能有效地渗透到岩石和煤块的小缝里面。固化时,形成粘塑性的块状,其粘性超过水粘性的1500倍。凝胶液及其组成试剂都是无毒的。形成凝胶体时所排放的气体不影响矿井气体分析仪检查矿井气体成份的精确度。 凝胶液具有隔离性能,在矿井的陷落区中 The gel solution has the advantages of increasing the air resistance of the goaf, increasing the water content in the air, coal and rocks, and reducing the absorption of oxygen by the coal for a long time. It is the most effective way to prevent spontaneous combustion of coal. The gel consists of water glass, ammonium sulfate and 92-95% water. With these proportions and concentrations of these compounds, curing times can range from a few seconds to a month or more to form a stable gel. The gel has an approximately water-like viscosity that effectively penetrates into the small pores of rock and coal lumps. Curing, the formation of viscoplastic block, the viscosity of more than 1500 times the viscosity of water. Gel fluid and its components are non-toxic reagents. The gas emitted when forming the gel does not affect the accuracy of the mine gas analyzer to check the gas composition of the mine. Gel fluid with isolation performance, in the pit of the mine area
