摘要
超高水材料是一种水体积可达95%～97%,水灰比接近11∶1的采空区充填材料。结合超高水材料的基本性能,针对近水平煤层充填开采的难点,提出了阻隔式充填方法,通过对地表移动变形的观测表明,充填对控制地表下沉产生了决定性作用。该充填方式成功实施说明:超高水材料是性能良好的采空区充填材料;超高水材料阻隔式填开采技术是一种适合于近水平煤层的充填方法。
Superhigh - water material is a kind of filling material in goal, whose water volume and water cement ratio can respectively reach 95% -97% and 11：1. Aiming at the shortcomings of goaf filling mining for nearly flat seam, partition filling mining with super high -water material is proposed. By analyzing the surface deformation, the results show that filling plays a decisive role in slowing down the land subsidence effectively. The success application in the Tianzhuang Coal Mine shows that super high -water material is a filling material with good performance in goal filling and the technology of partition filling mining with super high - water material is an advanced filling mining method for nearly flat seam.
