Municipal solid waste deep well sealing and filling mining method

Abstract

The invention provides a municipal solid waste deep well sealing and filling mining method and belongs to the technical field of mining engineering and environmental engineering. The municipal solid wastes are processed to form cubes or balls through a waste formation machine, the cubes or balls are transmitted to a mine enterprise from a treatment plant in peri-urban areas and then are conveyed to position under a well through a drilling pipe or an auxiliary shaft on the mine ground, then the cubes or balls are conveyed to a waste tunnel and a work surface through a flat car or a belt, closedtreatment on the municipal solid waste in a deep well waste tunnel is carried out through a volume filling technology according to different cases, and filling treatment on a replaced mine resource on a coalface through a strength filling process is carried out. The method solves the problem that the municipal waste treatment resource is limited and a mining waste space has a large space amount and a wide range, is a novel method for treatment on wastes with wastes and harm and disaster reduction for the city government and mine enterprise and is economic, environmentally friendly, safe and efficient.

Description

technical field [0001] The invention relates to the technical fields of mining engineering and environmental engineering, in particular to a deep well sealing and filling mining method for municipal solid waste. Background technique [0002] With the rapid growth of urbanization scale and population, the problem of urban waste disposal has become more and more prominent and acute. The waste disposal in my country started late, the overall disposal capacity of urban domestic waste is small, the technical level is still low, and the pollution is still serious. At present, my country's garbage disposal methods still have serious adverse effects on the health of residents around the garbage dump, resulting in opposition between the public and the government, and affecting the harmony and stability of the society. It is urgent to innovate a harmless treatment that is in line with the status quo of "under-classified" garbage in our country. Approach. [0003] On the other hand, th...

At present, my country's garbage disposal methods still have serious adverse effects on the health of residents around the garbage dump, resulting in opposition between the public and the government, and affecting the harmony and stability of the society. It is urgent to innovate a harmless treatment that is in line with the status quo of "under-classified" garbage in our country. Approach

[0003] On the other hand, there are a large number of abandoned mine roadways and goafs in my country, as well as roads and urban buildings on the surface that need to be protected but not exploited. Due to the lack of cheap filling materials, they cannot be filled in time, resulting in land subsidence and groundwater loss. , environmental pollution, waste of a large amount of valuable mineral resources and other issues have seriously affected the ecological environment and economic development of the mining area
