Description

Goaf collaborative disposal solid waste and associated resource exploitation method and system Technical Field The invention belongs to the technical field of goaf treatment and resource utilization, and relates to a method and a system for cooperatively disposing solid waste and associated resource exploitation in a goaf. Background During mining of mineral resources, a large number of underground cavities, i.e., goafs, are formed. If the goaf is not effectively treated, geological environment problems such as surface subsidence, groundwater pollution and the like can be caused, and mine safety production is seriously threatened. At the same time, various industrial production activities produce huge amounts of solid waste, and disposal problems are also serious environmental challenges. In addition, the goaf and the surrounding rock mass often have associated resources such as residual mineral products or coalbed methane which are not completely extracted, and have considerable recycling value. Currently, prior art solutions to the above problems are often conducted in isolation. For goaf management, a filling method is generally adopted, namely solid wastes such as tailings and fly ash or special filling materials are prepared into slurry and pumped into the goaf, so that the ground pressure is controlled, and the stability of surrounding rock is maintained. For exploitation of associated resources, independent drilling extraction and other technologies are adopted, and the two operations are separated from each other in terms of technological process, equipment system and time planning before or after filling operation. In the prior art, goaf disposal and associated resource exploitation are regarded as two independent and independent engineering links, and obvious defects exist. The filling operation often takes the compactness of filling and the stability guarantee as the primary targets, and the associated resources can be permanently stored in the filling body in the injection process, so that the resources can not be extracted to cause waste. Otherwise, if the resource exploitation is performed first, the stress state of the goaf may be changed to affect the safety and effect of the subsequent filling operation. Such technical fracturing results in lengthy procedures, high costs, low resource recovery and potential safety risks, failing to achieve synergistic optimization of multiple objectives.
