Embodiment Construction

[0036] The present invention is further illustrated by the following examples, but not limited to the following examples.

[0037] For example, the 1070 auxiliary transportation lane of Tashan Coal Mine can be used as the main place for filling and producing energy if the coal mine is abandoned due to mining of deeper coal seams in the future. The roadway is 2403m long, 6.6m wide and 3.97m high.

[0038] The method for filling the abandoned coal mine with garbage and producing biomass energy comprises the following steps:

[0039] (1) Screening urban waste:

[0040] The urban waste is firstly sorted by manual roughing to sort out the large objects, and then put the remaining materials into the simple screening machine (see figure 1 shown) to filter.

[0041] The working process of the simple screening machine is as follows: a small amount of garbage is slowly poured into the belt of the conveyor 2 from the feed port 1, the running speed of the belt is controlled to be 0.2m / ...

Abstract

The invention discloses a method for filling an abandoned roadway and preparing biomass energy sources by using garbage, and belongs to the field of comprehensive utilization of biotechnology and coal resources. The invention relates to a method for producing methane by combining the biotechnology and two resources of biomass garbage and the abandoned roadway. The method comprises the following steps of firstly, screening urban garbage and agriculture and forestry garbage; secondly, respectively culturing a bacterial colony for producing hydrogen and acetic acid bacteria and a bacterial colony for producing methane bacteria by using the biotechnology; selecting the abandoned roadway in which a coal mass is completely preserved, placing classified garbage and bacterial colony in the abandoned roadway, then injecting garbage slurry and water in the roadway, closing for enabling the filled roadway to form a sealing device, and producing methane by using biological fermentation. According to the method disclosed by the invention, the biomass garbage is used for filling the abandoned roadway, so that the waste of abandoned mine space and land resources can be solved, a microbiological method can be used for reducing macromolecular organic compounds in coal to produce the methane, further new energy sources are acquired, and the environment stress is alleviated.

Description

technical field [0001] The invention relates to a method for using garbage to fill abandoned shafts and produce biomass energy, specifically a method for producing methane by combining biotechnology with two major resources of biomass garbage and abandoned shafts, belonging to the field of comprehensive utilization of biotechnology and coal resources . Background technique [0002] With the development of modern human production, a lot of biomass waste is produced, which can be divided into urban waste, crop waste, forestry waste and so on. These wastes contain a large amount of organic matter and have great utilization value. Fully recycling and utilizing biomass waste not only reduces the city's damage to the environment, but also creates valuable resources. In recent years, the effective use of biomass waste has gradually emerged, but most of them are still landfilled on the surface. This treatment method will not only waste precious land resources, but also cause serio...
