Goaf solid waste and ultrahigh water paste alternate filling method
The invention discloses a goaf solid waste and ultrahigh water paste alternate filling method. The method involves solid waste paste filling and ultrahigh water paste filling in a goaf behind the samestope face, and staggered filling and grouting of the two materials is achieved. The method comprises the following specific filling steps that solid waste filling paste and ultrahigh water filling paste are prepared on the ground; the stoping working face is pushed forwards, after a hydraulic support moves, air bags are slightly deflated to release the filling space, and filling bags are hung and inflated; a working face pump station selects filling paste for grouting and filling according to the pressure of a top plate masonry beam; and along with the proceeding of the filling work, the airbags contract synchronously. According to the goaf solid waste and ultrahigh water paste alternate filling method, the problems that in the prior art, a single material is adopted, and the advantagesof different filling modes cannot be brought into full play are solved, the advantages of solid waste paste filling and ultrahigh water material filling are integrated, the filling cost is reduced onthe basis that the ground filling effect is guaranteed to the maximum extent, and the filling efficiency is improved.
本发明公开采空区固废‑超高水膏体交替充填方法，同一回采工作面后方采空区内包含固废膏体充填和超高水膏体充填，两种材料交错式充填注浆，具体充填步骤包括：地面制备固废充填膏体及超高水充填膏体；回采工作面向前推进，液压支架移动完成后，气囊轻微泄气释放充填空间，悬挂充填袋并进行充气；工作面泵站根据顶板砌体梁压力大小选择充填膏体进行注浆充填；随充填工作的进行，气囊进行同步收缩。本发明采空区固废‑超高水膏体交替充填方法，解决现有技术中采用单一材料，不能充分发挥不同充填方式自身优势的问题，综合固废膏体充填和超高水材料充填的优点，在最大限度的保证地面充填效果的基础上，实现降低充填成本，提高充填效率。
