Problems solved by technology
[0003] The object of the present invention is to provide an environment-friendly coal gangue brick to solve the problem of inconvenient alignment of two coal gangue bricks when laying most of the prior art with sound insulation coal gangue sintered bricks proposed in the above-mentioned background technology. It is necessary for the staff to use auxiliary measuring equipment, or to lay in a straight line based on their own rich experience, which is difficult to lay and low in laying efficiency.

The invention discloses an environment-friendly coal gangue brick, and relates to the field of coal gangue. The environment-friendly coal gangue brick comprises a brick body which is a cube on the whole, a locking piece which is fixed on one side of the brick body, a fixing piece which is fixed to the other side of the brick body, and is connected with the locking piece of another brick body in a matched mode, a limiting block which is fixed on the upper surface of the brick body, and a matching piece which is fixed on the lower surface of the brick body and is connected with the limiting block in a matched manner. In the prior art, when most sound-proof coal gangue sintered bricks are laid, two coal gangue bricks are not convenient to align, workers need to use auxiliary measuring equipment or lay the bricks into a straight line according to rich experience of the workers, as a result, the laying efficiency is low.With the environment-friendly coal gangue brick of the invention adopted, the above problem can be solved.
Description
technical field [0001] The invention relates to the field of coal gangue, in particular to an environment-friendly coal gangue brick. Background technique [0002] Coal gangue is a kind of rock associated and symbiotic with coal in the process of coal formation. It is a solid waste produced in the process of coal mining and cleaning processing. The amount of gangue discharged from coal mines accounts for about 10%-25% of the total coal mining. %, coal gangue has become the industrial solid waste with the largest accumulation volume and the most land occupation in my country. At present, the total stock of coal gangue in the country is about 4.5 billion tons, and it is still increasing year by year. Coal gangue contains residual coal, carbonaceous mudstone, and other combustible substances. After long-term accumulation in the open air, spontaneous combustion often occurs and emits a large amount of CO, CO2, SO2 and other organic harmful gases. Pollution of water resources is...
