Study Of The Gangue Characteristic And Comprehensive Utilization Of Xin-Wen Mining Area

Gangue to discharge and pile stock the heaviest one. If does not utilize, pile up it in the earth's surface for a long time, not only takes a large amount of land, influence the natural landscape, destroying the living environment in the district, and will also cause the emergence of the atmosphere, land, the water pollution and geological calamity. The comprehensive utilization of strengthening the gangue energetically is to protect the environment and implement the requiring doubly of sustainable development strategy. The physics and chemistry performance, the composition characteristic and main rock of each mining area gangue form under the key research Xinwen mining area of this text, utilize the way to be been appraised to the studying area gangue synthetically. Point out that the present main use way of gangue in the area is: make cement, building materials, use for and build the road, used as the fuel and generated electricity, quarry and select the associated mineral, produce organic fertilizer, etc. All these good gangue utilize way very, it is all right for a large amount of consumption to the gangue has shed, and accord with the request for developing recycle economy of mining area of coal, realize the sustainable development of production of mining industry. Make bricks to fill a prescription newly while testing in the waste rock, Have considered the waste rock and the main materialization nature of the fly ash, main factor of adding the proportion, roast temperature etc of the fly ash as the raw materials, have drawn gangue of making -The best batching proportion of the fly ash brick. Through to regard as power fuel used for generating electricity gangue go on firm sulfur experiment study, feasibility of proving the sulfur-fixing agent of using limestone and dolomite as and carrying on the firm sulfur, draw the best experiment condition of the firm sulfur. A new method of toxicity removal of chromium residual was introduced in this paper, which was to use gangue, chromium residual and other materials. The method could remove the toxicity chromium residual completely and stable, it would be an effective way to treat chromium residual. Develop and utilize opening up a new direction for the gangue in the study area.
