Rui Nuo support material —— Deformation control and support technology of underground roadway and airway in coal mine
Product Description
This product is a fully inorganic mineral powder material. During application, it should be directly mixed with water at appropriate ratios using a dedicated construction pump, combined with RuiNuo Pillar filling bags for installation. RuiNuo Pillar features rapid and stable filling capability, high structural strength, and easy cutting adaptability for coal cutters. It also demonstrates advantages such as minimal deformation under pressure, high residual support strength, large coverage area, and long-distance pumping capabilities.
