Material for building temporary airtight wall in coal mine well and airtight wall building method
The invention discloses a material for building a temporary airtight wall in a coal mine well and an airtight wall building method. The material comprises following components in percentage by weight:95 to 98.6% of silicate cement, 0.8 to 2.2% of sodium dodecyl sulfonate, 0.2 to 0.8% of building rubber powder, 0.2 to 1.2% of calcium formate, and 0.1 to 0.8% of polypropylene fiber filaments. The components mentioned above are evenly mixed, added into 36 to 40% of water, and evenly mixed. The mixture is injected into an isolation space by a special facility. The isolation space is arranged on the cross section of a tunnel; is enclosed by a metal screen, whose pore size is not less than 100 meshes, and has a width of 0.5 to 2 meters. The provided method has the advantages that the using amount of materials is low, the cost is low, the heat generated during the curing process is small, the high temperature resistant performance is good, and the construction period for building a temporaryairtight wall is short.
本发明公开了一种煤矿井下临时密闭墙用材料及其密闭墙建立方法，包括硅酸盐水泥95％～98.6％、十二烷基磺酸钠0.8％～2.2％、建筑胶粉0.2％～0.8％、甲酸钙0.2％～1.2％、聚丙烯纤维丝0.1％～0.8％混合均匀，加入材料质量36％～40％的水中搅拌均匀，用专用设备注入在巷道内断面处布设的孔径不小于100目金属网宽度为0.5～2m的隔离空间内。通过本发明方法能够实现材料用量少、成本低、固化过程产生热量小、耐高温性能好、施工周期短的临时密闭墙建立的目的。
