Study on the Technique of Filling Paste into Mine Goaf with Building Waste

Abstract:

Some hot environmental issues existed at present such as building waste dump, mine subsidence and unexploited coal under buildings, railways, and water were analyzed, discussing the research status of building waste, as recycled aggregate, and technology of paste filling into mine goaf, then, the feasibility of filling the building waste into goaf was proposed. Finally, the paste filling orientation, strength, pumpability, stability, filling process design of recycled aggregate and benefit evaluation were analyzed.
