Safe mining method and safe mining structure for valley type domestic garbage landfill

Abstract

The invention discloses a safe mining method and a safe mining structure for a valley type domestic garbage landfill, and belongs to the field of solid waste resource utilization. The mining method comprises four main technical units of development transportation, drainage, slope stabilization and ventilation, wherein the development transportation technology is that independent ascending and descending roads which are built through a multilayer annular horizontal road and an ascending and descending connection ramp is adopted; the drainage technology is that rainwater is drained by self flowing in an external intercepting ditch, a pump station inside is divided by areas, the drained sewage is lifted in a grading way to the top for treatment and then is drained after reaching the standard;the slope stabilization technology is that a double slope protection technology of geogrids and ecological bags is adopted; and the ventilation technology is a technology of combining natural guide and artificial forced ventilation. A safe and efficient reservoir area constructed by the safe mining method is used for developing a transportation road, and the stored garbage is timely transported out from the mining position; and moreover, the safety of the mining operation of the landfill is fully guaranteed through improvement on drainage, slope stability and ventilation.

Description

technical field [0001] The invention relates to the field of resource utilization of solid waste, in particular to a safe mining method and mining structure of a valley-type domestic garbage landfill. Background technique [0002] my country's cities and towns produce about 200 million tons of domestic waste every year, of which more than 60% are disposed of by landfill technology. In addition, more than 8 billion tons of domestic waste have been landfilled over the years. The pollution situation is severe, a large amount of land is occupied, and the resource potential is huge. It is of great practical significance to solve the problem of domestic waste to use the "urban mine" technology to safely mine, effectively sort and classify the existing domestic waste. According to the different natural terrain conditions used in the landfill area, domestic waste landfills are roughly divided into three types: valley-type landfills, plain-type landfills, and tidal flat-type landfil...
