新型矿用充填钢模板研制及应用

Development and application of a new type of mine-used filling steel formwork

介绍了一种可伸缩式的新型充填钢模板装备和技术,其可代替现有柔模支护技术。采用钢模板支护技术可沿采空区留巷位置连续形成一个混凝土墙式支护结构,使巷道能够及时支护,降低了沿空留巷的费用和劳动强度,提高了生产效率及施工速度,保证施工安全。

The author introduced a new extension type of filling steel formwork equipment and technology, which could replace existing flexible support technology. With the new technolo- gy, a continuous concrete wall type support structure would be formed in the location of gob-side entry retaining to provide timely support. It could decrease the maintenance cost and the labor in- tensity of gob-side entry retaining and improve the production efficiency and construction speed, at the same time, it could ensure the safety in construction.
