Embodiment 1

[0019] Example 1. As figure 1 Shown, a kind of method that utilizes coal gangue to prepare planting brick and the structure of planting brick,

Embodiment 1

[0021] The preparation method of described planting brick comprises:

[0022] S1, putting coal gangue into stone crushing equipment for processing to obtain stone powder;

[0023] S2. Add 50 parts by weight of kitchen waste, 15 parts by weight of potassium nitrate, 15 parts by weight of calcium chloride, 20 parts by weight of magnesium sulfate and 18 parts by weight of iron salt to 150 parts by weight of the stone powder. After uniformity, the mixture is obtained;

[0024] S3. Spread the mixed material indoors into a stone pile with a height of 15 cm, and irradiate it with an ultraviolet lamp with a frequency of 200 nm for 20 min;

[0025] S4. Spray 25 parts by weight of mixed bacteria liquid and 55 parts by weight of water into the stone pile after ultraviolet lamp irradiation to obtain a mixture. After placing the mixture at 50°C for 4 days, add 30 parts by weight of a mass fraction of 10 % lemonade, then placed at 65°C for 2 days, and finally at 35°C for 5 days to obtain ...

Embodiment 2

[0028] The preparation method of planting brick comprises:

[0029] S1, putting coal gangue into stone crushing equipment for processing to obtain stone powder;

Abstract

The invention discloses a method for preparing a planting brick by coal gangues and a planting brick structure. According to the method, the coal gangues can be effectively combined with the plantingbrick, so that resources are comprehensively used. According to the planting brick structure, brick bodies are conveniently connected by the aid of bumps and grooves, construction efficiency can be improved, and the planting brick has good air permeability and hygroscopicity by the aid of circular through holes.

Description

technical field [0001] The invention relates to a method for preparing planting bricks by using coal gangue and a structure of the planting bricks, belonging to the field of comprehensive utilization of waste solids in coal mining. Background technique [0002] Coal gangue is a kind of coal-containing kaolin associated with coal, and the comprehensive discharge of coal gangue accounts for 10% to 15% of the raw coal output. A large amount of coal gangue generated during coal mining has been piled up around coal mines as bulk solid waste in the past. my country has accumulatively stockpiled 4.5 billion tons of coal gangue, occupying about 15,000 m2 of land, and generating 300 to 350 million tons of coal gangue every year. It is currently one of the largest industrial and mining solid wastes in China. The stacking of coal gangue not only takes up a lot of land, but also produces dust when the surface water evaporates in windy weather. Long-term exposure to the air is suscepti...
