| Coal gangue is produced in the process of coal production of solid waste, because of our province to major coal-producing province, abundant gangue lands, covers an area of big, releasing large amounts of toxic gas in the storage process, cause serious harm to the environment, coal gangue mountain management, recovery and rebuilding the damaged ecological environment has become a very urgent and realistic problem. Because of spontaneous combustion gangue mountain itself, weathering and leaching characteristics, combining the domestic and foreign research situation of comprehensive control of gangue hills, through on-the-spot of nanping mountain in west coal mine comprehensive governance of coal gangue piles and research analysis, test results are as follows:1:in the test concrete using solid mountain, a thorough fire, a natural succession process for the configuration principle of plant community landscape effect, eventually reach regulation effect.2:the tests showed that the comprehensive treatment of coal gangue mountain basis is to realize the stable of the mountain and fire extinguishing thoroughly. Fire extinguishing the combination of the following methods to:jet grouting fire construction, invisible extinguishing fire, furrowing grouting construction the construction technology, ring toe closed fire construction, the effect is remarkable.3:on the vegetation restoration, test the substrate improvement technology combined with remote spray seeding technique for the repair of coal gangue piles and combining with the physical environment in order to achieve the maintenance, stable ecological system. After field repair, evaluate found effective. |
