The invention relates to a plugging material for underworkings. The plugging material for underworkings comprises the following components in parts by weight: 1.0 part of cement, 1.5-2.5 parts of soil and 0.03-0.08 part of concrete accelerator. The plugging material for underworkings is available in raw materials and low in cost, is easy to prepare and can be largely used; the material is good in wall attachment property, high in work efficiency and good in plugging and air leakage effect; the material has good stripping property; and in the working face stopping process, the roadway support material can be easily recycled, thus the support material can be reused and the cost can be reduced.
