城市垃圾充填煤矿采空区控制地表沉陷技术研究

Research on Control Techniques of Surface Subsidence by Stowing Municipal Solid Wastes in Coalmine Gobs

对当前两大环境问题(矿山地表沉陷和城市垃圾)所造成的危害进行了分析研究,根据城市垃圾处理和矿山充填开采研究现状,对当前利用城市垃圾充填煤矿采空区控制地表沉陷技术进行分析,提出其今后的研究重点:城市垃圾压缩及其固化性能关键技术,利用城市垃圾充填煤矿采空区的充填工艺设计,充填设备研究与开发,以及如何采取科学有效的手段防止垃圾充填可能造成的各种危害。

Two current major environmental problems,i.e.,the harms induced by the surface subsidence in mines and the solid waste in cities were analyzed and according to the research status of municipal waste treatment and mining technology with stowing in mines,the paper proposed the future research thrusts of key technologies including the compression and solidification of municipal solid wastes,the design of stowing technology by using the city rubbish to fill gobs in coalmines,the research and development of stowing equipment and the adoption of effective scientific means to control all hazards induced by waste stowing.
